Full complement cylindrical roller bearings

Full complement cylindrical roller bearings are cage-free, meaning that a maximum number of rolling elements can be accommodated. For this reason, full complement bearings can be subjected to particularly high radial loads, while the limiting speed is significantly lower than that of cylindrical roller bearings. Thanks to shoulders that are appropriately situated at the bearing rings, the bearings also carry axial forces in one direction. For axial counterstay, place a second bearing mirror-inverted to the first. Single row full complement cylindrical roller bearings are — except for NJG VH series — not detachable. In single row full complement cylindrical roller bearings, the main dimensions are standardized according to ISO 15 Radial bearings — boundary dimensions , DIN Roller bearings — boundary dimensions or DIN Roller bearings — cylindrical roller bearings — single row. As the default, we manufacture single-row full complement cylindrical roller bearings at SLF with standard tolerances PN according to DIN Roller bearing tolerances — tolerances for radial bearings and ISO Radial bearings — dimensions and tolerances. We also deliver the bearings with other tolerances. Bearings in the NCF V, NCF V and NCF V series are equipped with two fixed shoulders at the inner ring and one fixed shoulder at the outer ring. Axial forces are only transmitted in the direction of the fixed outer ring shoulder.

As a result, axial displacements of the shaft relative to the housing can be compensated within certain limits.

These bearings use cylindrical rollers as the rolling elements and have a high load capacity. The rollers are guided by the ribs of the inner or outer ring. The inner and outer rings can be separated to facilitate assembly, since both inner and outer ring are normally press fitted to the shaft and housing, respectively. The rings can move freely in the axial direction on those with no inner or outer ring ribs, making cylindrical roller bearings ideal for applications that experience thermal expansion of the shaft, such as electric motors. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. By chemically altering the surface chemistry of the roller, NTN is able to create a thin layer of retained austenite that results in compressive stresses that increase bearing life. AS Treatment results in a material life multiplier of 1.

Full complement cylindrical roller bearings

A full complement cylindrical roller bearing is a further enhanced variant of the cylindrical roller bearing which incorporates as many multiple rollers as possible, but these are not equipped with a cage like the other row variants with multiple rollers. These variants are categorised under radial roller bearings. There are solid outer rings, inner rings and rolling element sets that are assembled to form this bearing.

The specific suitability of a bearing for an application in terms of installation space, load carrying capacity or speed limit for example, must be checked independently of this. In addition to the bearings described here, Schaeffler supplies single row full complement cylindrical roller bearings in other types, series and dimensions. The permissible guide values at which, based on experience, there is no significant reduction in operating life are as follows:. The bearing temperature during operation is therefore significantly lower. In the event of anticipated temperatures which lie outside the stated values, please contact Schaeffler. Rolling bearings are well-proven precision machine elements for the design of economical and reliable bearing arrangements, which offer high operational security. Slots in outer ring. Schaeffler Noise Index The SGI value is based on the maximum permissible noise level of a bearing in accordance with internal standards, which is calculated on the basis of ISO Influencing factors, such as the conditions of rotation, magnitude of the load, internal clearance, temperature conditions, design of the mating parts and the mounting and dismounting options must be taken into consideration in the selection of fits. Seal on both sides 40 Without Full complement cylindrical roller bearings are cageless.

Easy grease replenishment Lubrication holes supplied in the inner ring allow for grease in sealed types to be easily refilled and replaced. The better the lubrication and in particular the heat dissipation, the higher the permissible axial load. Brand protection. If shock type loads occur, tight fits transition fit or interference fit are required to prevent the rings from coming loose at any point. Global Global Website English.
