FRICTION ROLLERS

Welker's friction rollers are powdered metal components designed for economy, long life, and maintenance-free performance. One-piece roller and 3-piece roller systems are available:

The one piece roller runs on a hardened shaft, generally positioned with set collars or spacers.

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.
