• Metric or inch series

• Open or closed end

• Open, single seal (U) or double sealed design (UU)

• Relubrication holes are available on larger sizes (above 10 mm bore)

• Full complement of rollers 

• Special internal clearance and special heat treatments

• A limited range is offered in AISI 440C Stainless Steel


The power of having options means that you can pick and choose what you need. So what should you consider using needle roller bearings for? Common applications include:
