Spacer bearing assemblies speed up bearing installation time because there is no need for bearing adjustment. Spacer bearing assemblies are suitable for use with two-row and four-row Timken® tapered roller bearings to preset the bench lateral (bench end play). Most matched bearing assemblies have serial numbers to ensure correct installation sequence.

Timken spacer bearings are precisely ground to provide the exact bench lateral required for the particular bearing application.Since each spacer is custom-fitted to a particular set of components, a spacer cannot be used with any other bearing components – even if they carry the same part numbers.Bearings of this type use conical rollers guided by a back-face rib on the cone. These bearings are capable of taking high radial loads and axial loads in one direction.

In the HR series, the rollers are increased in both size and number giving it an even higher load capacity. They are generally mounted in pairs in a manner similar to single-row angular contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting the axial distance between the cones or cups of the two opposed bearings. Since they are separable, the cone assemblies and cups can be mounted independently.Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle.Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.
