Pulleys for Wire Rope—For Horizontal Pulling
Also known as sheaves, use these pulleys to assist with horizontal pulling or to guide a rope.
Pulleys with a bearing are easier to turn than pulleys without a bearing. Ball bearings and needle-roller bearings allow for easier turns than sleeve bearings.
Acetal and nylon are lightweight and corrosion resistant.

Easy-Open Hanging Pulleys for Wire Rope—For Horizontal Pulling
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. Use them to assist with horizontal pulling or to guide a rope.
Style D pulleys have a corrosion-resistant stainless steel housing.

Hanging Pulleys for 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.
Acetal, nylon, and aluminum are lightweight and corrosion resistant. Styles C, H, and P have a bracket on the bottom for tying off one end of a rope.
Style J reduce the force needed to hold your load in place. Unlike standard pulleys, these have a V-groove for more grip on your rope, and they ratchet when under load so they won't slip in the other direction. Pulley for 3/8" dia. rope can be set to ratchet even when not under load.

Machinable Pulleys
Customize the groove and bore to fit your application. The center of the pulley has a pilot hole so you can drill a bore to match a specific shaft size. Nylon is easy to machine yet resists impact and corrosion.
Pulleys for Wire Rope—For Lifting
Use the bore to mount these pulleys on a shaft. These pulleys are also known as sheaves.
Nylon pulleys are lighter in weight than steel pulleys.
Warning: Never use to lift people or items over people.

Pulley Diameter Checkers
Also known as groove gauges, these measure the groove of your pulley to check for wear as well as determine the correct wire rope size.
