Shaft Mount Gear Reducers

Shaft-mount gear reducers ride directly on the driven shaft and react torque through a fixed arm, eliminating the baseplate, coupling, and alignment work a footed reducer demands. The result is a fast, field-serviceable drive that has earned a permanent place on conveyor head and tail pulleys, mining apron feeders, roller beds, ribbon mixers, and oil-and-gas surface equipment. Common frames standardize on bushing-fit bores, which makes brand cross-references practical when an older unit reaches end of life.

Northwest Power Products stocks the most-requested shaft-mount frames — Dodge TXT, Browning, Boston Gear, and equivalents — in Tacoma, with bushing kits, torque arms, and backstop accessories on hand for emergency swaps. We cross-reference legacy units on bore, torque rating, ratio, and bushing fit before quoting a replacement, and rebuild in-house when the housing and shaft are recoverable. Field-swap coordination, planned-maintenance staging, and 24/7 emergency support are routine for the conveyor and aggregate operators we serve across the Pacific Northwest.
