Apply continuous tension and automatically take up slack at any point in a 180° arc.
Maintain correct drive tension to ensure smooth operation for maximum power and a long service life.
Designed for large belt and chain drives, these tensioners maintain correct drive tension for smooth operation, maximum power, and a long service life.
Precisely apply tension in a straight line by moving the adjustment screw.
Position the adjustment arm to control tension in a 360° arc.
These tensioners range in height from 5 15/32" to 7 25/32".
Able to fit in tight spots, these tensioners are less than 3" tall.
At less than 4" in height, these tensioners are good for use on low-clearance drives.
Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension.
Install these rings between strands of chain to absorb slack without the need for realignment, lubrication, or tools—good for use in confined spaces where maintenance may be difficult.
These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration.
Also known as paper-plant pulleys, these are made of a paper-fiber composite that minimizes belt slippage and wear.
Pulleys are anodized aluminum, which is more corrosion resistant than steel.
Acetal and aluminum construction makes these pulleys useful in for weight-sensitive applications.
Pulleys are XL series (extra light) and have trapezoidal teeth.
Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.
These L series (light) pulleys and have trapezoidal teeth.
Carry heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.
Anodized aluminum has good corrosion resistance.
Made from polycarbonate, these pulleys are useful in applications with weight constraints.
Pulleys are H series (heavy) and have trapezoidal teeth.
Move heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.
Made of aluminum, these pulleys have good corrosion resistance.
Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners to remove slack from timing belts.
These HTD (high torque drive) pulleys have a curved tooth shape that provides higher strength than trapezoidal teeth.
Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.
Mount these high torque drive (HTD) pulleys onto a hex shaft.
Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws.
Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth.
For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics.
Machine your own timing belt pulleys to fit the exact width and shaft diameter needed.
These pulleys are cast iron.
Choose from nylon, UHMW, and zinc.
A built-in spring maintains tension on your belt.
Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys.
Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove.
These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration.
Use these pulleys with compatible quick-disconnect bushings.
These pulleys have the same sizing versatility as quick-disconnect pulleys, but they create a tighter grip on bushings for use in high-torque applications.
Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.
Mount these pulleys directly onto a shaft to transmit rotary motion and torque.
Use on a conveyor pulley with a conveyor belt tensioner to adjust the tension on a conveyor belt.
A tensioner extends or retracts the conveyor pulley to adjust the tension on the conveyor belt.
These tensioners have a totally enclosed adjusting screw to prevent debris buildup and thread damage.
Machine your own gears to fit the exact face width and shaft diameter required.
