Deep-Channel Roller Chain Guides

Guide

Guide with Flanged Frame

Also known as captured guides, deep-channel guides prevent chain from slipping off track. Use them to minimize friction, reduce noise, and prolong the life of your roller chain. They can be cut to the exact length you need.

Guides with flanged frame allow easy mounting. Stainless steel frames are more corrosion resistant than steel frames.

Made-to-Order Guards for Chain and Belt Drives

If none of our standard guards fit your chain or belt system, we'll create one to suit your needs. Guards prevent chain and belt slippage and protect your drive mechanism from interference. To mount, punch screw holes or weld.

Select the sprocket center-to-center size range that matches your system. Then specify the following dimensions: sprocket center-to-center; large sprocket OD; small sprocket OD; clearance between sprocket and side of guard (2" of clearance is recommended); and guard depth (1" of clearance is recommended).
