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.
Angular Adjustment—The right choice for applications with a 20° and greater angle between the motor and driven unit. Just turn a hex nut to tilt your motor up or down for better belt positioning.
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.

Dry-Running Electric Slides for Stepper Motors
 |
With PTFE sleeve bearings and a low-friction ball screw, these slides don’t require the mess and maintenance of lubrication but still give you precise positioning anywhere along the length of their stroke. Because they have sleeve bearings, they have fewer moving parts, so they perform better in dusty and wet environments than slides with ball bearings. They’re also better at handling impact and vibration.
All slides require a stepper motor, driver, and controller (not included) to operate. As part of this system, they move in precise increments, like the head on an inkjet printer. These electric slides work well for automated assemblies and other applications that require fine, repeatable motion control.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.
