    Maximize your belt-driven system’s efficiency while minimizing wear on bearings, pulleys, and other components. Made in the U.S., these adjustable mounts secure motors in the perfect position for proper belt tension. Make fine adjustments or tension the belt with a quick turn of the screw, hex nut, or hand crank. Choose a mount that fits the NEMA frame of your motor, which is listed on the nameplate.
    For Constant Motor Speeds—These mounts keep motors tightly secured while operating equipment with a fixed speed, such as fans. You can only adjust the motor position when your system is off.
    For Variable Motor Speeds—These mounts let you move the motor while the system runs to adjust for vibrations and varying loads. They’re best-suited for HVAC motors, cleated conveyors on an incline, and other systems with fluctuating power demands.
    Automatic Tensioning—Mounts with automatic tensioning include shock-absorbing springs that compensate for bumps and vibrations, similar to the suspension in a car. Ideal for rock crushers and other machinery with irregular and challenging workloads, they reduce maintenance costs and help bearings, belts, and pullers last longer.
