Maintain correct drive tension to ensure smooth operation for maximum power and a long service life.

Precisely apply tension in a straight line by moving the adjustment screw.

Able to fit in tight spots, these tensioners are less than 3" tall.

Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension.

Choose from nylon, UHMW, and zinc.

A built-in spring maintains tension on your belt.

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.

Use these pulleys with compatible quick-disconnect bushings.

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.

These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration.

Hooks at each end of the cable insert into the rollers beyond the links you want to change. Tighten the hooks with the included box wrench to add or remove a link. Maximum jaw capacity is 42".

The closed body protects threads from damage and debris and has a slim profile to fit in tight spaces.

Weld these stubs to parts or use them to push objects apart instead of pulling them together.

Use on a conveyor pulley with a conveyor belt tensioner to adjust the tension on a conveyor belt.

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

For specialty applications and connections, these springs have unique end types.

A black-oxide finish provides mild corrosion resistance.

These zinc-plated steel springs have mild corrosion resistance.

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

The springs in these assortments have deep hooks that are less likely to slip off compared to standard extension springs.

The more you extend these springs, the greater the force the springs will exert to pull the two points back together. They're commonly used to tension cable, return an air cylinder to its starting point, and hold a door closed.

These tensioners apply maximum tension to pull strapping more tightly around packages than standard tensioners for metal strapping.

These tools do double duty, pulling metal strapping tight and then sealing it, without the use of a separate seal.

Use these tensioners with buckles in low-tension applications to draw plastic strapping tight around packages.
