Exact same as above except that the side plates are all regular thickness. The strength with the CS Kind chains is less than the PT Variety but higher than the SL kind. Attachments with typical dimen-sions can be utilized for this series and so they are really typically utilized on smaller materials dealing with conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to help keep lubricating grease in although preventing the penetration of dirt together with other contaminants to the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to maintain lubricating grease in while stopping the penetration of filth along with other contaminants in to the pin/bushing bearing region.
