Allen-Bradley 284T Adjustable Motor Mounting Base

The Allen-Bradley 284T Adjustable Motor Mounting Base is a heavy-duty, horizontal, sliding mounting platform designed for NEMA 284T frame motors, making motor installation, alignment, and belt tension adjustment straightforward in belt-driven equipment. Built from heavy-duty steel with twin adjusting screws, it allows precise motor positioning and easy belt tensioning, reducing maintenance time and improving belt life in conveyors, pumps, compressors, fans, blowers, and other industrial power transmission setups. Mounting bolts and washers are included where applicable (model dependent); the base is finished with a factory primer and oven-baked corrosion-resistant coating for durable service in continuous-duty environments and serves as a direct replacement for compatible NEMA 284T motor bases. Typical users include maintenance teams and system integrators performing new installations, equipment upgrades, and replacement of worn bases in manufacturing plants, HVAC systems, agricultural equipment, and material handling machinery. Common replacements include Baldor B284T Adjustable Motor Base, Worldwide Electric W284T Motor Slide Base, and Marathon 284B2 Adjustable Motor Base.
