Restriction of dimension

Normally the space allowed to install SKF bearings is restricted. In most cases, SKF bearings inner ring diameter is restricted by the mechanical design or other designs. Thus, the SKF bearings type and dimension choice are subject to SKF bearings inner ring diameter.

There are several dimensions for SKF bearings and in the machinery designing we should have better knowledge of how to use SKF bearings dimension. The load rating in SKF bearings, its nature, size, and direction is changeable. Normally, the basic load ratings are displayed on the dimension table and the axial and radial loadings are also one of the important factors to choose suited SKF bearings.

The Rotation Speed

The rotation speed is confirmed by the SKF bearings type, dimension, precision, cage type, loading, and lubrication type and so on. Normally, the deep groove ball bearings, self-aligning ball bearings, and cylindrical roller bearings are suitable for high-speed application.

The Tolerance

SKF bearing’s dimensional accuracy and rotation accuracy is according to the ISO standard. For high-precision and high-speed machines, it is recommended to use SKF precision bearing, Class 5 or above class.

Installation and disassembling

In some working condition, we need to install and dismount the bearings frequently in order to maintain and inspect the local place. The bearings which can be installed by inner ring and outer ring separately are as follows: - cylindrical roller bearings, needle roller bearings, and tapered roller bearings
