R3-2'o'-ring chain - links only available.
R3-2 is an evolution of the original R3 chain
7% increase in tensile strength
10% increase in chain life
Nitrile 'O' Rings extend chain life by retaining special vacuum injected grease inside the chain joint
Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance
High carbon alloy steel bearing pins for excellent resistance to wear
Gold coloured side plates help prevent corrosion
Pre stretched to enhance performance of the chain
This chain has been superceded by the R3-3 chain.
