Renthal R3-3 SRS 520 Off-Road Chain

Renthal R3-3 chains are specially developed utilising Renthal’s SRS technology to increase the service life. The special SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain. This offers increased longevity, as the specially formulated grease remains encapsulated around the critical pin and bushing area longer whilst preventing ingress of dirt, water and other contaminants.

Features:

• To help with an easy setup, each R3 chain is pre stretched meaning adjustments are not required
• Nitrile Self Regulating Seals (SRSTM) retain a special vacuum injected grease around the critical pin and bush area, which extends the life of the chain
• Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
• Special finish: gold coloured side plates and copper coloured rollers help prevent corrosion.
• Tensile strength 7420 lbs
