Welker CIP Composite, Rulon, Bronze Bearings and Friction Rollers

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.
