TIMKEN tapered roller bearings spacer assemblies

TIMKEN tapered roller bearings spacer assemblies
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.

When ordering replacement bearing assemblies, specify:

  • cone number
  • assembly number.

If you do not have the assembly number, specify the component part numbers including:

  • cone number
  • cup number
  • spacer number
  • bench end play, which is etched on the spacer.

If you do not have any part numbers for the spacer assembly, specify:

  • Name of equipment
  • Model number
  • Year
  • Application position of the bearing.
