W-18S-MPB SilentSync Sprocket

SilentSync Sprockets
Continuous rolling tooth engagement allows belt to enter sprocket with minimal impact, wear and operating noise, thus creating longer-lasting, quieter drives Does not require flanges; helical offset tooth design allows belt to self-track.
MPB = (Minimum Plain Bore) referrers to plain bore or MPB, simply un-tapered bores drilled through the center of a sprocket. We also offer alteration for non standard bore sizes.
SilentSync’s patented Helical Offset Tooth (H.O.T.) design merges belt and sprocket into the quietest, smoothest and one of the most compact synchronous drive packages available. The result is a continuous rolling tooth engagement that reduces vibration and improves the overall efficiency of your drive system. Matching belt see White Belts section for this sprocket.
