NEPEAN Longwall has been designing, building and installing our own sprocket assemblies since 2002. High powered AFC systems are very demanding on the sprocket drives and we have a proven engineering approach which has resulted in consistent high performing sprocket assemblies for the AFC and BSL. We are supported by our partners supplying high quality forged sprocket rings and PW Hueber (Germany) is our first choice. With demanding requirements for dimensional accuracy and material specification including industry-leading case hardness depth, PW Hueber is working with NEPEAN Longwall and Fasing (longwall chains) to continue to develop this technology and provide improved sprocket and chain life. We can supply replacement sprocket rings, full sprocket assemblies or overhaul of your existing sprocket assemblies. All our work is tested and run prior to release. Our sprocket range runs from 34mm to 50mm.
