Standard Properties of Servicing Free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction produced amongst the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which could hold a higher volume of oil.
PT Style Roller Chains

These chains possess rollers to smooth the action over sprocket teeth. Roller website link plates are 1 size thicker to increase strength. Side plates and pins have unique coatings to stop rust.
C-Type Roller Chains
