Top chain accessories - Set Collars

Set Collars are components designed for idlers and sprockets for Top Chains.
Set Collars can be used to prevent misalignment of idlers and sprockets for Top Chains in the shaft direction caused by operating temperature changes or chain snaking.
We offer a wide array of set collars stocked, so they can be readily used in designing conveyors.
Lighter than metallic products as they are made of plastic.
Split types for easy installation/removal with no disassembling of conveyors or shafts required.

・ Model numbers in parentheses have a set collar with an outer diameter larger than the hub. Check for interference with conveyor components such as rails around idlers and sprockets.

・ Idlers and sprockets that are not shown on this page can not be used, as set collars interfere with chains.
