Martin Sprocket & Gear 40B18SS Sprocket Wheel

Martin Sprocket & Gear 40B18SS Sprocket Wheel is a chain-drive sprocket designed to transfer rotary motion between parallel shafts in mechanical power transmission systems, relying on a toothed wheel meshing with a compatible chain to maintain precise timing and load distribution. It features a 7/8 inch wide profile and a 3/16 inch keyway (KW) that together provide a robust mounting interface on a keyed shaft and stable chain engagement, helping minimize slippage under load and ensuring consistent torque transmission. The 40B18SS designation identifies the specific configuration within Martin's catalog, guiding selection for matching drive trains and alignment with the corresponding chain pitch and shaft geometry. Intended for standard chain-drive assemblies, this sprocket serves as a practical, readily integrable component when a keyed mounting and defined width are required in industrial equipment and machinery. Users specify model 40B18SS when their system calls for Martin's established design standards, consistent with other components in the 40B18SS family and compatible with common chain drive configurations.
