Bearings

Welker helps customers explore new bearing options and technologies that offer lubrication free, high-performance products along with traditional bronze bearings.
Our selection guide will help people select the right bearing alternative for their product or equipment.  Traditional SAE660 bronze bearings are offered in standard sizes or machined to customer specifications.
Alternative bearings such as CIP and reinforced PTFE offer built in lubrication, high load/low friction performance and the ability to operate in hostile environments
