Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction designed concerning the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and therefore use thick sectioned powdered metal bushings which could hold a substantial volume of oil.
PT Form Roller Chains

These chains possess rollers to smooth the action above sprocket teeth. Roller hyperlink plates are one particular dimension thicker to improve power. Side plates and pins have special coatings to avoid rust.
C-Type Roller Chains
Exact same as above except the side plates are all common thickness. The strength of your CS Form chains is under the PT Type but better compared to the SL variety. Attachments with common dimen-sions can be used for this series and therefore they can be often employed on small material managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in when preventing the penetration of filth along with other contaminants into the pin/bush-ing bearing region.
