TIDC India manufactures Sprocket Kit with Rubber `0` Ring Seal. TIDC India has obtained ISO/TS 16949 certification for Cam chain and Fine blanking divisions, ISO 9001:2000 certification for Quality System and received ISO 14001 Certification for Environmental Management. This Sprocket Kit with Rubber `0` Ring Seal is known as Diamond Legend `0` Ring Kits. This rubber `0` ring seal of sprocket kit is made up of a special rubber, which prevents the lubricant between the pin and the bush from spilling out. This special `0` ring always prevents the wear of the pin and thus reduces elongation of the chain in the most rough driving condition and increases the life of the chain by at least 3 times compared to the regular/normal bullet chain. This chain combined with the special black cast iron Sprocket Kit with Rubber `0` Ring Seal is suitable for rough driving conditions.
