RHV Sprockets


Sprockets for use with HERO, HV and DSZ - round steel chains with replaceable and adjustable individual teeth, made from MnCr alloyed steel, case hardened – highly wear resistant. Sprockets are welded steel fabrications, any number of teeth or hub design is available. Keyways are machined in the hubs of matched wheels to ensure precise alignment of the teeth. Hub design, bore diameter and key size can be specified by the customer. Shimplates can be fitted to adapt the pitch circle dia. of the sprocket to a chain lengthened due to wear in the interlink points of contact. This ensures continued smooth running of the chain over the sprocket and the maximum use of the case hardened layer in the chain. Shimplates and new teeth can be mounted without disassembly the chain.
