Bison Gear’s Hollow Shaft Gearmotor Doubles Continuous Torque Ratings

Bison Gear’s new 562 series hollow shaft gearmotor offers increased low speed center distance coupled with greater clearance for wider faced gears. According to the company’s press release, the gearmotor allows for up to 1,100 in.-lbs. continuous torque, twice traditional continuous torque ratings. An optional fourth stage of gear reduction is possible as well, providing ratios up to 2,200:1 in the same envelope, allowing for a smaller input motor without sacrificing output torque. Additional features include hollow shaft options with multiple configurations and various AC and DC input motors, including three-phase and inverter duty. A hollow bore diameter of 3/4" allows for interchangeable shaft designs. Bison Gear also introduced low voltage additions to its 750 series right-angle gearmotor design. New additions consist of two input motor options rated at 1/8 hp, 12 VDC, and 1/8 hp, 24 VDC. Gear ratios will be 5, 10, 13, 20, 30, 45 and 60 to 1 and available from stock with a 3/4" diameter hollow shaft with face mount or a 5/8" diameter solid shaft insert with steel footplate. These options allow uses of battery power and other low voltage applications.
