Bison Gear Adds 562 Series to FlexTorq(TM) Hollow Shaft Gearmotors

Versatile design offers opportunity to replace less efficient right angle worm gearing, while offering higher torque in a compact package.

St. Charles, IL - October 5, 2009 - Gearmotor and electric motor manufacturer, Bison Gear & Engineering Corp. has added 46 models of its 562 Series of hollow shaft offset gearmotors to its growing FlexTorq(TM) line of products. With a slightly larger footprint than a conventional right angle worm reducer gearmotor, the FlexTorq(TM) units provide from two to nine times more output torque, depending on the gear ratio utilized.

The 562 Series of FlexTorq(TM) gearmotors is offered in seven 115 volt, single-phase 1/20 hp (37.3 watt) versions and thirty nine DC versions with 12, 24, 90 and 130 volt inputs and powers of 1/8 and 1/20 hp (93.2 and 37.3 watts). Continuous output torques range from 66 to 1100 in-lbs (7.5 to 124.3 N-m), with corresponding fixed output speeds from 65 to 1.3 rpm.

"We find that special machine builders and OEMs really like the unique FlexTorq(TM) design because its offset parallel shaft configuration fits into a lot of tight spaces and it has exceptional torque density," said John Morehead, Bison Gear's vice president, strategic planning and marketing. "The fact that the hollow shaft units can be optioned with single or double output shafts in any of three diameters or fitted with one of our TightDrive(TM) integral speed controls makes them truly versatile."

The FlexTorq(TM) gearmotors are manufactured in Bison Gear's suburban Chicago facility to Bison's high quality standards in order to ensure a short supply chain and reliable, long-life operation. In addition, Bison's Innopreneurial(TM) application and design engineering capabilities to customize standard models to meet specific OEM needs are readily available.
