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.

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.

Steinmeyer Precision Ball Screws has been dedicated to precision since 1920. In those early days, as well as today, it was close collaboration with our customers, and continued improvement of our products and services, that enabled them to rely on us with confidence. But, we invite you to experience this yourself!

Steinmeyer manufactures ball screws from 3 mm to 160 mm in diameter. For ball screws from 3 to 16 mm diameter we offer several standard shafts for various strokes, with choice of ball nut and one of two types of bearing journals. Custom versions of both nut and shaft are also available.

Precision Ball Screws 3 - 16 mm Diameter, Ground ThreadStandard or Custom.

Whether you select a standard item from our extensive product range, or are looking for something specifically tailored to your needs: you just came to the right place! It's not a far-fetched guess that the smaller screw in the photo above is not a standard item. Nevertheless our list of standard screws is the right place to start collecting information.

Steinmeyer produces ball screws for machine tool and similar use with custom shafts only. For a quote, we just need a drawing or sketch that sufficiently defines the shaft.

The nut can be a standard one shown on the following pages, or custom. Even for the custom version, you may obtain useful information from the listing of technical data, since load capacities, rigidity or friction torque will be the same as in the corresponding standard version. Of course we are also prepared to assist you in selecting a nut that best meets your needs, recommend the right preload setting or provide minimum nut dimensions to yield a given life expectancy of the unit.

Rotating Nuts

Steinmeyer ball nuts are ideal for rotating nut designs because they are inherently mass balanced due to the symmetrical orientation of the ball deflectors. Driven (rotating) nuts and stationary shafts offer a number of advantages over conventional layouts (and some disadvantages):

• Resonance of the shaft is not as critical. Higher speeds may be reached when the shaft is not rotating.
• Pre-tensioning of the shaft is simplified, since the necessary forces do not need to be transmitted through bearings. Heating is reduced significantly.
• Stationary shafts allow easy internal cooling of the screw.

UltraThrust ball screws from Steinmeyer are not merely larger sizes of conventional ball screws. They have been specifically designed for the purpose of transmitting very high loads. The ball returns for example have been optimized for large ball sizes and for the specific use of such large screws. Also the robust nut body and the flange differ from conventional designs. Material selection and heat treatment take into account the special application requirements.

Ball Screws for Aerospace ApplicationsSteinmeyer produces ball screws for aerospace applications to existing customer designs, or we design and develop our own solution in accordance with customer specifications. With a proven variety of products, 40+ years of experience in ball screw production, and EN 9100 (AS 9100) approved quality system, our expertise is second to none in the global market.

These Ultra miniature ball screws are manufactured from standard tool steel, hardened and then precision ground to meet ISO tolerances from P0 to P5. Stainless steel material is available as an option.

Steinmeyer’s miniature ball screws are ideal for applications in:
