Plastic combination roller chain
Lube free plastic combination roller chain also known as PC chain is totally lubrication free with corrosion protection properties. No lubricant is required so maintenance costs are greatly reduced and productivity and chain life increased.
Plastic combination lube free chain is 50% lighter than BS standard roller chain and is much quieter in operation. It is constructed using high performance engineered plastic for the inner link which combines lubricity and wear resistance with the stiffness and strength required in parts designed to replace metal.The bearing pins and outer plates are manufactured from high grade 304 steel.
Sintered bush roller chain
Widely known as lube free chain, sintered bush roller chain is actually a self lube chain or SLR chain. It combines the key features of standard roller chain but requires no further lubrication once installed. It's oil-impregnated sintered bushing works in combination with a specially treated bearing pin.
Self lube chain is maintenance free and provides effective, long-term internal lubrication without the use of O-rings, resulting in greatly extended life and reduced sprocket wear compared to standard roller chain.
Sealed for life roller chain
Sealed for life roller chain is a maintenance free roller chain that is often called lube free. It is lubricated but the lubrication is sealed in.
It is also referred to as O or X-ring chain and sealed for life chain as lubricant is contained by tiny O-rings positioned between each pin link and roller link plate. The lubrication is kept in due to the seal between the plates and dirt is kept out.
This type of lube free chain provides better wear life than standard types of roller chain.
