About Pulleys

Compare standard, hanging, and mounted pulleys, then calculate the capacity you need based on the angle of your rope.

Pulleys for Rope—For Horizontal Pulling


Aluminum	Stainless Steel	Acetal

Also known as sheaves, use these pulleys to assist with horizontal pulling or to guide a rope.

Ball Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Needle Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Aluminum and Acetal—Acetal and aluminum are lightweight and corrosion resistant.

Stainless Steel—Stainless steel is the most corrosion resistant.

Hanging Pulleys for Rope—For Horizontal Pulling


Style A	Style B	Style C	Style D	Style E

Style F	Style G	Style H	Style J	Style K

Style L	Style M	Style N	Style Q

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

2 Grooves—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.

Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

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

Style J—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.

Aluminum and Acetal—Acetal and aluminum are lightweight and corrosion resistant.

Nylon Housing—Nylon is lightweight and corrosion resistant.

Easy-Open Hanging Pulleys for Rope—For Horizontal Pulling


Aluminum	Stainless Steel

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.

Needle Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Aluminum—Aluminum is more lightweight than stainless steel.

Stainless Steel—Stainless steel is more corrosion resistant than aluminum.

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.
