A Sprocket is a wheel with profiled teeth machined around its circumference that mesh with a chain or a track.  They do not mesh together directly but are driven normally by a chain of the same pitch and roller diameter.  They are commonly found on bicycles, motorcycles or any machinery that requires transmitting rotary motion between two shafts where gears are unsuitable for their use.

LMR produces a vast number of sprockets mainly for the marine industry where they are extensively used.  The company has the benefit of CNC controlled Rigid Hobbers that give us a very competitive profile in this industry.
