525VX3x120 Heavy Duty X-Ring DID Chain

D.I.D’s X-Ring construction reduces friction by twisting the side plates instead of being squashed. D.I.D’s sealed chains incorporate D.I.D’s special “V” grease in the pin/bushing area and lock dirt out. They are expected to last at least ten times longer than standard chains without significant wear elongation under satisfactory maintenance.

• X Ring four contact points greatly increasing sealing performance, keeps dirt out and maintains lubrication.
• Ultra low friction X-shaped seal rings preventing inner lubrication loss.
• Pre-lubricated at factory, ensuring low friction and maximum durability.
• Proven high tensile strength, D.I.D X Ring has the greatest wear resistance of any other type of O-Ring or non O-Ring chain.
• Solid bushes for enhanced distortion resistance from repetitive shock loading.
• ZJ (rivet) link provides the same durability and resistance to fatigue as exhibited by regular riveted links of chain. This race developed link will be fitted to all machines with sealed ring chains, riveted connection to make the chain endless is recommended for maximum strength and safety achieved by a unique design of shouldered pin. A riveting tool is required.
