Precision Bearing

Product Details:

Egis Precision Flat Cage Guidance Systems, a medium-sized Swiss company, has specialized in making precision linear guidance systems for 50 years. Egis systems are essential in fields such as machine tool construction, printing machines, measurement technology, automation, robotics, optics, productronics, and medical technology.

In addition to standard high-precision guideways, EGIS also produces them in made-to-measure lengths, the associated flat and angled flat cage assemblies, and offers manufacturing possibilities for special parts to suit customer requirements.

Egis M and V Guideways with Needle or Cylindrical Roller Flat Cage Assembly

M and V guideways are combined with angled flat cage assemblies and are particularly suitable for high load carrying capacities, rigidity, minimal friction and a high level of accuracy. They are used as linear locating bearings. They are manufactured in standard lengths up to a maximum of 1,000 mm which allows for rapid delivery.

In order to respond to specific customer requirements, the guideways in this range can also be supplied in made-to-measure lengths, i.e. in any required length up to the maximum length specified in the dimension table.

The guidance systems can be set to be free of clearance or can be preloaded to enhance rigidity using pressure screws.

 

Egis ML Guideways with Adjusting GIB for Needle Roller Flat Cage Assemblies

This series combines an M guideway with an adjusting gib which distributes the preload equally over the entire length of the guidance system.

The pitch of the gib surface is 1.5%. ML guideways fulfill optimum requirements in terms of rigidity and precision.

Egis MVZ (M/V/ML) Guideways with Integrated Toothed Rack for Positive Control of the Needle Roller Flat Cage Assembly

In this series, the angled flat cage assembly is subjected to positive control by an integrated toothed wheel/toothed rack unit. This guarantees perfect movement for the flat cage assembly even under difficult operating conditions.

Egis M and ML Guideways with Sliding Layer Product Quick Despcription

The guideways in this series consist of an unhardened guideway with a layer fixed by adhesive. They are combined with V guideways and possess the same mounting dimensions as the M/ML and V guideways with flat cage assemblies. They are used in particular when an increased level of friction is required to provide damping or when static or pulsating loads are involved.

Egis S and J Guideways with Needle Roller Flat Cage Assembly

These guideways are used in combination with needle roller flat cage assemblies as linear non-locating bearings. They are supplied in two versions, one of which possesses a flat structure and is therefore space-saving whilst the other has the same dimensions as the corresponding M and V guideways.

Egis LUE Counterstay Systems with Needle Roller and Cylindrical Roller Flat Cage Assemblies

 These units consist of a locating guidance system, a non-locating guidance system and an L counterstay which preloads the two guidance systems. This arrangement prevents the system from becoming distorted by thermal expansion.

Egis Flat Cage Assemblies

Flat cage assemblies consist of a basic cage made from plastic or metal and a large number of precisely guided rolling elements. Needle rollers provide a minimal construction height and optimum load carrying capacity and rigidity whilst cylindrical rollers are less demanding with regard to the connecting structure and have a slightly less rigidity. Balls create the lowest level of friction of all rolling bearings.

Flat cage assemblies are designed for use with precision guideways but can also be used directly with customer-specific elements with appropriate raceways.

Angular Contact Bearings:
Fafnir angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions.

The special geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads. Different designs offer contact angles ranging from 20° to 40°. Higher angles provide more axial load capacity for longer service life operating under axial and radial loads.

Typical Applications:

• General industrial
• Chemical
• Utilities
• Agricultural
• Expanded Options
• Special lubricants
• Special cage materials
• Special preloads
• Special coatings for corrosion resistance

2MM-WI types with 15° initial contact angle are designed to meet the needs of machine builders for precision bearings which will operate at as low a temperature as possible for a wide range of speeds and operating loads. In order for machines to produce more accurate work at a higher production rate, the bearings must provide a high degree of rigidity in both axial and radial directions while operating a minimum temperatures. For example, precision machining or cutting tools impose heavier loads on bearings than those encountered in precision grinding. In the former, speeds are slower and loads heavier than the latter, where speeds are high and loads light.

3MM-WI types, manufactured with 25° contact angle, are for use on applications where the loading on the bearings is predominately thrust — and a high degree of axial rigidity is a definite requirement. Typical applications for these are large vertical rotary surface grinders, horizontal and vertical disc grinders, and thrust bearing applications for heavy duty lathes where the bearings must directly carry extremely high tail stock or chucking pressure.

2MM-WO types with 15°-18° initial contact angle are designed for extremely high-speed applications where centrifugal force of the balls is the principal load on the bearing. Unlike the MM-WI type which has a low shoulder outer ring, the 2MM-WO type has full shoulders on both sides of the outer race and a low shoulder on one side of the inner ring.

2MM-WN types with 15° initial contact angle are designed to meet the needs of machine manufacturers who require optimum oil flow through the bearings.This design incorporates a low shoulder on the non-thrust side of both the inner and outer rings.

2MMV and 3MMV 99100WN types are available with 15° or 25° contact angle variations and have been developed to operate under the demanding requirements of high speed machine tools. They incorporate design features which permit operation at higher speed than standard angular contact ball bearings. The bore, outside diameter, and width are the same as the MM9100 series.

HX Types are dimensionally interchangeable with equivalent 9100, 99100 and ISO Series-10 bearings. These designs enable spindle heads to remove more material in less time while maintaining superior machining tolerances. HX bearings come with steel or ceramic ball complements with a 15 degree standard contact angle in a WN construction design.

• Ball bearings

Ball bearings are a sub-category of roller bearings. In ball bearings, rolling elements between a inner ring and an outer ring reduce frictional resistance, in contrast to lubrication in the case of plain bearings. The rings secure axles and shafts by absorbing radial and/or axial forces, depending on the structural form, while allowing the rotation of the shaft or components mounted on an axle (for example, a wheel). Rolling friction mostly occurs between the three main components of inner ring, outer ring and rolling element. Since the rolling elements in the inner and outer ring roll on hardened steel surfaces with optimised lubrication, the rolling friction of these bearings is relatively low.

• Deep-groove ball bearings

Deep-groove ball bearings are particularly versatile. In addition to allowing the absorption of radial loads, they simultaneously enable the absorption of axial loads in both directions. They are of simple construction, durable in operation and maintenance and suitable for high to very high rotational speeds.

 

• Axial deep-groove ball bearings

Axial deep-groove ball bearings are suitable for supporting axial loads but must not be subjected to radial loads. Axial deep-groove ball bearings are not self-retaining and consist of the shaft washer, housing washer and ball set retained by a cage. Depending on the application, they are manufactured as single or double-direction bearings. Single-direction axial deep-groove ball bearings are suitable for absorbing axial forces in one direction and can thus support the shaft to one side. Double-direction axial deep-groove ball bearings, by contrast, can absorb axial forces in both directions and thus, as locating bearings, they support the guidance of the shaft to both sides.

• Angular contact ball bearings

Single-row angular contact ball bearings are non-separable bearings with solid inner and outer and rings whose raceways are offset against each other in the direction of the bearing shaft. This allows angular contact ball bearings to be subjected to radial and axial loads. They only absorb axial forces in one direction and thus need to be adjusted against a second bearing. Single-row angular contact ball bearings are designed for high rotational speeds.

Series L Ball screw support bearings are specially designed for high performance machine tools, where extreme rigidity requirements preclude the use of standard angular contact bearings. The internal configuration has been designed to provide an optimum combination of high rigidity, low drag and exceptional control of lateral runout and long life. Contact angle is high at 65° to provide axial rigidity and the very high thrust capacity.

Also available are the 7602., 7603 and BSB (15 mm width) series.

Spindle Bearings

Barden offers both Angular Contact and Deep Groove Spindle Bearings that are made to exacting Abec 7 or Abec 9 specifications, standards that Barden routinely exceeds.

Angular Contact bearings support thrust loads or combinations of radial and thrust loads in one direction while a deep groove spindle bearing can accept radial loads thrust loads (limited) in either direction or a combination of loads.

Instrument Ball Bearings

Barden offers both Angular contact and Deep Groove Instrument Bearings.

Angular Contact Instrument Bearings

Angular contact bearings have one ring shoulder partially or totally removed. This allows a larger ball complement than found in comparable deep groove bearings, hence a greater load capacity. Speed capability is also greater.

Angular contact bearings are assembled to a contact angle by varying the radial clearance. Instrument angular contact bearings have nominal contact angles of either 10° or 15°.

Separable and non-separable types are available. In a separable bearing (B type), the cage holds the balls in place so that the outer ring assembly (with cage and balls) can be separated from the inner ring.

Separable bearings are useful where bearings must be installed in blind holes or where press fits are required, both on the shaft and in the housing. The separable feature also permits dynamic balancing of a rotating component with inner ring mounted in place, apart from the outer ring and housing.

Angular contact bearings support thrust loads or combinations of radial and thrust loading. They cannot accept radial loads only — a thrust load of sufficient magnitude must be present. An individual angular contact bearing can be thrust-loaded in only one direction; this load may be a working load or a preload.

Deep Groove Instrument Bearings

Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads.

Product Details:

GMN produces high precision spindle bearings with more than 95 years of manufacturing experience. Spindle bearings are also referred to as angular contact bearings, and they transmit and externally applied load from one ring to the other along a specific contact angle. GMN Angular Contact Ball Bearing also produces machining spindles, free-wheel clutches, non-contact seals and many unique products for special projects. GMN prides itself on being fast and agile to adapt products for special applications.

Bearing Series S:

GMN standard spindle bearing.

Bearing Series SM:

Geometry of inner ring modified for extremely high speeds. Reduced load rating and static rigidity compared to bearing series S.

Bearing Series SH:

A special design of series SM. Optimized oil feeding, one land on inner ring.

Bearing Series SMI:

A special design of series SM.

Optimized for total loss lubrication and extremely high speeds, it eliminates the need for the high oil feed, seal, and cooling system complexity of an oil injection system.

Separable Type:

Simple mounting due to separate installation of inner and outer ring (when necessary). Balancing of rotating parts with installed inner ring.

Bearing Series BHT:

The cage retains the balls in the outer ring, which means the balls do not fall out when the one-land inner ring is removed.

Bearing Series BNT:

Corresponds essentially to bearing series BHT. However the contact conditions are the same as for bearing series S.

Bearing Series: X And BHT.X

Non-separable type:

High precision ball bearings of extra wide design with shields on both sides for high speed and grease lubrication are used in drilling, milling or grinding spindles for special operating conditions.
