Keyway Rollers

Keyway Rollers are a unique way of providing a guidance system to a Hilman Rollers. Whereas an Accu-Roll Guidance System is external of the standard size roller frame, a Keyway Roller has what we call an internal Guidance System. The keyway style chain is designed to remain centered to the frame (straight or radius). This type of chain should be used on high cycle life applications or applications where the roller may be used in a vertical manner. Keyway Chains have a groove machined into the rolls that mates with a track that is machined into the roller frame’s load plate
