Martin Sprocket & Gear 50BS12 Bored-To-Size Sprocket

Martin Sprocket & Gear 50BS12 bored-to-size sprocket with a 1" bore is a standard power-transmission sprocket designed for on-site bore customization. The bored-to-size configuration means the sprocket is prepared to be machined to the exact shaft diameter, delivering a precise, slip-free fit in chain-drive systems. This model, 50BS12, from Martin Sprocket & Gear, provides a 1" bore option to accommodate 1" shafts in industrial equipment, conveyors, and other machinery that use chain drives. Mounting requires machining to final shaft size and proper securing hardware as part of a typical setup; ensure the bore finish and runout are within your equipment's tolerances for reliable operation. As a product from a trusted manufacturer of power-transmission components, this bored-to-size sprocket is intended for applications where a custom-fit bore is preferred over a fixed sprocket bore. Use in conjunction with compatible chain and drive components, and ensure alignment and proper tensioning to maximize service life.
