Cylindrical Roller Bearing

Product Details:

INA Cylindrical Roller Bearing:

Single row INA Cylindrical Roller Bearing with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers coming into contact with each other during rolling.

The INA cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.

The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both Bearing rings can therefore have an interference fit.

Low-Friction INA Cylindrical Roller Bearings:

Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.

INA High Precision Cylindrical Roller Bearings:

Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.

The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

INA Full Complement Cylindrical Roller Bearings:

Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings and in single and double row designs.

INA Cylindrical Roller Bearings with SNAP Ring Grooves:

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.

The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place.

Locating Bearings:

Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are highly rigid and can support axial forces in both directions as well as high radial forces.

Due to the full complement design of these bearings, they have the largest possible number of rolling elements and thus extremely high basic dynamic and static load ratings.

Bearings For Cable Sheaves:

Due to the grooves in the outer ring, the bearing rings can be axially located with ease. The bearings are therefore very suitable in bearing arrangements for cable sheaves.

Product Details:

NTN Bower Cylindrical Roller Bearing have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

INA 

The company was founded in 1946, and achieved an industrial breakthrough in 1949 with the development of the needle roller and cage assembly by Georg Schaeffler. In 1952, an INA needle roller bearing replaced the previously used plain bearings in the transmission of the VW Beetle. Today, almost every modern passenger car contains INA engine and transmission components.

Variable cam timers and hydraulic bucket tappets ensure improved performance, reduced fuel consumption, lower emissions, and increased driving comfort in modern car engines. INA rolling bearings, engine components, and linear technology are characterized by a high level of quality and reliability.

INA CYLINDRICAL ROLLER BEARINGS 

Single-row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling. Cylindrical roller bearings can be supplied with or without a cage.

Full-complement INA cylindrical roller bearings + FAG cylindrical roller bearings with cages = Solutions for every application

There is nothing that cannot be improved. We developed the TB roller to significantly increase bearing operating life under an axial load. TB as in TorusBallig (torus shaped). The special curvature of the end faces of this roller enables loads to be distributed across a significantly greater surface area. The curved roller end face increases the size of the contact surface and thus significantly reduces the contact pressure.

INA PLAIN BEARINGS, MAINTENANCE AND MAINTENANCE FREE STEEL AND BRONZE PLAIN BEARINGS 

Plain bearing and rod end designs that require maintenance with steel/steel and steel/bronze material pairs are easy to maintain, cost effective, and excellently suited to alternating loads. Plain bushes, washers, and strips employ the low-maintenance metal-polymer composite E50. The sliding layer features lubricant pockets, which means that an initial lubrication is sufficient in most cases.

INA MAINTENANCE FREE PLAIN BEARINGS

Schaeffler offers a comprehensive catalog of maintenance-free plain bearings. Innovative plain bearing materials are used here, such as ELGOGLIDE, ELGOTEX, and the metal-polymer composite E40. These PTFE plain bearing materials enable ultra-low coefficients of friction for spherical plain bearings and rod ends as well as bushes, washers and strips while ensuring low wear and very long life cycles. Maintenance-free plain bearings considerably reduce lubricant and maintenance costs as they do not require any oil or grease while also being very environmentally friendly.

 

Product Details:

Rollway Cylindrical Roller Bearing are manufactured in a number of designs; the predominant type being the single row roller. The roller and cage assembly are guided axially by the integral flanges (ribs) on one of the bearing rings. This design facilitates ease of mounting and dismounting, particularly where both races are an interference fit on their seating. Roller bearings with flanges (ribs) on one race only do not provide any end location.

Various Roller Bearings with ribs on both races provide axial location, and are capable of carrying light or intermittent axial loading. These patterns are of the NJ, NUP, NJ and HJ types. If used for axial location and light axial loads the contact between the flanges (ribs) and the roller ends is that of a sliding bearing, not rolling bearing, therefore lubrication is of paramount importance. Double row and full complement Cylindrical Roller Bearings are also manufactured.

Product Details:

Four-row cylindrical roller bearings are suitable for very high radial loads due to the large number of rolling elements. They are used almost exclusively for back-up rolls in rolling mills.  Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

Product Details:

FAG tapered roller bearings can support high radial and axial loads. They have a broad range of speeds. They are efficient at supporting forces and ensure a precise and rigid shaft guidance system due to the large effective distance between the bearings. Tapered roller bearings can be adjusted and dismantled, which makes mounting easy.

Due to the inclined position of the rollers, tapered roller bearings can support both radial and axial forces. Four-row and double row tapered roller bearings are used in rolling mills.
Due to the inclined position of the rollers, tapered roller bearings can support both radial and axial forces. Four-row and double row tapered roller bearings are used in rolling mills.
Tapered roller bearings are separable; unlike cylindrical roller bearings, however, it is not possible to fit the inner rings on the neck first, mount the outer rings in the chock and then slide the chock onto the roll neck. The complete bearing must instead be mounted in the chock, after which the chock together with the bearing is slid onto the neck. This means that the bearing inner ring must have a loose fit on the neck, although it should technically have a tight fit due to the circumferential load. With a loose fit, the inner ring will inevitably creep on the neck. The neck will undergo heating and wear in this case. Wear can be restricted by good lubrication of the fit joint between the inner ring and roll neck.
