Welker Bearings & Friction Rollers
- 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.

Friction Rollers
The 3-piece design eliminates the roller riding directly on the shaft, allowing the use of soft shafting - positioned by pinning the flange and collar to the shaft, thereby providing greater driving force. 3-piece rollers are specifically recommended for inclined sections and areas where pallet acceleration from stops is critical.Catalog
