Buying Guide
Specifying Taper Roller Bearings
What to confirm before ordering.
Step 01
Match the exact designation
Cup and cone numbers are matched, always order or replace them as a set unless the housing bore is unchanged.
Step 02
Set correct preload or end play
Taper roller bearings need axial setting on installation, incorrect preload causes early failure.
Step 03
Confirm metric or inch
Metric and inch series are not interchangeable despite similar appearance, check the stamped designation.

FAQ
Frequently Asked Questions
Common questions about taper roller bearings, answered by our counter team.
Should I replace the cup and cone together?
Yes, always. They wear as a matched pair, replacing only one leads to uneven contact and early failure.
How do I set the correct end play?
Follow the equipment manufacturer's specified preload or end play procedure, usually measured with a dial indicator during installation, we can advise for common applications.
Can I identify a bearing from the stamped numbers?
Yes, send us a photo of the cup and cone stampings and we will confirm the exact designation and stock availability.
Need a cup and cone set priced?
Send the stamped numbers on WhatsApp and we will confirm stock the same working day.
