Industrial UR146-HM5 Right Angle Gear Reducer

The Boston Gear UR146-HM5 is a 1:1 ratio right-angle bevel gear reducer that redirects torque between intersecting shafts without changing speed, making it ideal for directional power transmission in compact layouts. It is commonly installed in conveyor systems, packaging machinery, material handling equipment, pumps, and other industrial automation applications where a 90-degree shaft orientation is required. Key specifications include a 1:1 gear ratio, bevel/miter gear drive, and a 90° shaft arrangement, with an input horsepower rating of approximately 26.376 HP (application dependent). The housing is cast iron or industrial alloy, and mounting options include foot or flange mount depending on configuration; lubrication can be oil bath or grease depending on setup. It provides high-efficiency power transfer, with operating speed variable based on system input and reversible CW/CCW rotation, suited for medium to heavy-duty industrial service. Common replacements used in compatible drive trains include Boston Gear R158-BM1 spiral bevel gear drive, Winsmith 1:1 right-angle bevel gearbox, and Dodge 1:1 right-angle miter gearbox.
