Sprockets can be quoted in various bore sizes or styles with non standard or timed keyways and hardened teeth (hardness will be Rockwell “C” 35-45). Bore sizes and hub diameters larger than the standards specified are available. Specify requirements when quoting or ordering. Welded construction (Style E) sprockets can be produced as solid construction. We can manufacture any of the sizes shown as multi-strand sprockets, or we have tooling to make larger single or multi-strand sprockets up to 48" in diameter.

Sprockets can be quoted in various bore sizes or styles with non standard or timed keyways and hardened teeth (hardness will be Rockwell “C” 35-45). Bore sizes and hub diameters larger than the standards specified are available. Specify requirements when quoting or ordering. Welded construction (Style E) sprockets can be produced as solid construction. We can manufacture any of the sizes shown as multi-strand sprockets, or we have tooling to make larger single or multi-strand sprockets up to 48" in diameter.

We have tooling to produce larger pitch sprockets also. Send your inquires for #120, #140, #160, #180 and #200 chain sprockets. We can supply single or multi-strand sprockets up to 48’’ in Diameter.
