1.1 Bush chain (Rollerless chain) catalogue sections
1.2 Roller conveyor chain Catalogue sections
1.3 Drag Link Chain Catalogue sections
1.1 and 1.3 with chain sliding are simple in construction and often therefore more economic, and are more effective in dirty and/or unlubricated environments. A greater Horsepower is required.
1.2 Chain Rolling encourages smoother operation with less surging. Lower friction allows for longer centre distances. Not suited to dirty enviroments as ingress of materials between bush and roller and roller and linkplate will encourage seizure. Less horse power is required so smaller motors and reduced operational cost will be available.
