Pulley Hoists


Steel with Mechanical Brake	Stainless Steel and Plastic with Cleat Brake

These hoists come with fibrous rope that is lighter in weight and easier to handle than chain.

Warning: Never use to lift people or items over people.

Plastic Body and Stainless Steel Body—Stainless steel and plastic hoists are corrosion resistant.

Mechanical Brake—Mechanical brake automatically holds your load in place when you stop pulling the rope.

Cleat Brake—Cleat brake locks by pulling the rope through the cleat to hold your load in place.

Ultra-High-Torque GT Timing Belt Pulleys

Pair these pulleys with the strongest timing belts we offer, Ultra-High-Torque GT Timing Belts. They can handle as much torque as roller chain. Their curved teeth fit snugly with matching belts for minimal play (backlash), so these pulleys are good for applications that require precise positioning. All are compatible with Gates Poly Chain GT timing belts.

Steel and Iron—Strong but best for dry environments since moisture will cause them to rust.

Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

Taper-Lock Bushing-Bore V-Belt Drive Pulleys

Mount these drive pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft. These pulleys transfer force from the shaft to a V-belt in a power transmission system, and also help with misalignment. Made of cast iron, these pulleys are durable and resist wear.

Depending on the taper-lock bushing you choose, the same drive pulley can be used with different shaft diameters.

Precision High-Torque GT Timing Belt Pulleys

Bushing Bore

When precise synchronization is crucial, these pulleys minimize play (backlash). They’re often found in 3D printers, where accurate positioning is essential. Their curved teeth fit snugly with matching belts. Compared to pulleys with standard trapezoidal teeth, these pulleys transmit about three times more torque and run at higher speeds. All are compatible with Gates PowerGrip GT, 2GT, GT2, GT3, and GT4 series.

Iron—Strong but best for dry environments since moisture will cause them to rust.

Overhead-Mount Window Balancers


Use pliers to pull the spring’s load clip to attach an object.

Mount these balancers in the corner of a horizontal frame to suspend, lift, or lower objects that move vertically in a track such as windows, doors, and panels. All have a spring that provides constant resistance throughout the travel length to suspend objects with minimal effort. Use pliers to pull the spring’s load clip to attach an object. Once the object is attached, the spring is released until the object is balanced.

While these balancers can be used individually on doors and panels, they are often used in pairs to ensure smooth movement. When used on windows, two are required for each sash. All of these balancers are rated for weights—make sure the weight of the object falls within the weight range listed. The load capacity stamped on each balancer is the load capacity for a pair.
