V-Belt Pulleys

Visibly worn pulleys. One of the first symptoms of an issue with an idler pulley is visible wear on the pulley. ... Belt squealing. Another common symptom of a possible issue with the idler pulley is squealing from the engine belts. ... Damaged bearing or pulley.

Fixed Eye Single Sheave Pulleys are heavy duty, durable and used to raise loads of an indicated amount of weight. Each pulley has an oil impregnated bearing to extend pulley life. Axle and sheave are removable. Do not use with wire rope or cable.

Sheaves and pulleys are round wheels with a flat or grooved edge that transmit rotational force from one shaft to another when connected with a V-belt or gearbelt. They are typically used to power fans, pumps, conveyors, and other industrial machinery.

A pulley is a rope wrapped around a wheel. It changes the direction of force. A basic compound pulley has a rope attached to a stationary point looped around one wheel and then around a second wheel. Pulling on the rope pulls the two wheels closer together.

A fixed pulley with no sheave changes the direction in which the force is applied to move the heavy load, but it does not change the amount of force needed. Using multiple sheaves gives you a mechanical advantage.

The Raydafon belts and pulleys are designed specifically for linear motion. They use a rounded tooth profile that guarantees that the belt tooth fits smoothly and accurately in the pulley groove, so when you reverse the pulley direction, there is no room for the belt to move in the groove.
