Taper-Lock Bushing-Bore V-Belt Pulleys

2 Grooves

Mount these 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 pulley can be used with different shaft diameters.

Mounted Pulleys for Wire Rope—For Horizontal Pulling

Styles 2-4, 6, and 7

Mount these pulleys to a flat surface to assist with horizontal pulling or to guide a rope.

Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load.

Hanging Pulleys for Wire Rope—For Horizontal Pulling

Hang these pulleys from hooks, screws, and bolts to assist with horizontal pulling or to guide a rope.

Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load. They have a bracket on the bottom for tying off one end of your wire rope.

Stainless steel is the most corrosion resistant.

Acetal, nylon, and aluminum are lightweight and corrosion resistant. Stainless steel is the most corrosion resistant.

Styles C, H, and P have a bracket on the bottom for tying off one end of a rope.

Pulley for 3/8" dia. rope can be set to ratchet even when not under load.

Mounted Pulleys for Wire Rope—For Lifting

Mount these pulleys to a flat surface.

Pulleys with two grooves are for use in applications where multiple pulleys move a single load, such as block and tackle systems. They can reduce the force needed to move the load by up to two times compared to single-groove pulleys.

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

Easy-Open Hanging Pulleys for Wire Rope—For Lifting

Also known as snatch blocks, these pulleys open so it's easier to feed the rope through the housing—a free rope end is not needed.

Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load.

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