V-belt pulleys (also called sheaves) are working with V-belts to transfer motion from motors to belts, fans, and pumps. They have V-shaped grooves corresponding to V-shaped belts to prevent slippage and misalignment. V-belt pulleys provide maximum friction and torque in compatible V-belt drive systems.
Available in single or double grooves, they offer a pitch range from 1.9 inches to 6.7 inches (A belt) and 2.4 inches to 7.0 inches (B belt). 1VP and 2VP series are finished-bore variable speed sheaves’ material is cast iron. Designated for heavier duty service up to 25 HP. Variable pitch pulleys are working with 3L, 4L, 5L, A, B, or 5v belts.

Agricultural Engineering Machinery Pulley
The Agricultural Engineering Machinery Pulley is a key component in agricultural machinery, responsible for transmitting power from the engine to other parts of the equipment.It is designed with a grooved surface to ensure proper traction and prevent belt slippage during operation.The working principle of the drive pulley involves rotating the belt around the pulley to transfer power efficiently.
V Belt Garden Machinery Pulley
The V Belt Garden Machinery Pulley is essential components within various Garden machinery, serving tasks like belt-driven power transmission and conveying operations. They often adhere to standard pulley dimensions for compatibility with widely used V-belts, but some may also be application-specific.
PK Belt Water Pump Pulley For Auto
The PK Belt Water Pump Pulley is a critical part of an automobile’s cooling system, and it’s essential to ensure that it’s functioning correctly.This small yet important pulley is responsible for driving and controlling the speed of the water pump, which in turn circulates coolant throughout the engine. Without it, the water pump would fail to operate, leading to overheating and potential engine damage.
Flat Belt Water Pump Pulley For Auto
The Flat Belt Water Pump Pulley is engineered to maintain optimal coolant circulation, supporting stable operating temperatures and reliable performance across a wide range of cooling system parts applications.The Flat Belt Water Pump Pulley is very important parts of the cooling system of an engine that allow the fluid to flow easily and keep the engine at the best temperature.
V Belt Water Pump Pulley For Auto
Water pump pulleys are circular mechanical machineries on the water pump shaft. Their main role is to take rotational energy, which is on the crankshaft of the engine, and transfer it to the pump’s internal impeller. They serve as the connection point to the engine cooling system parts, provide the mechanism of coolant flow that ensures that your engine does not exceed the safe operating range of temperatures.

5TB Series 5-Groove Cast Iron Sheaves with Split Taper Bushings
5TB series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts, ranging from 3.75″ to 38.35″ in diameter. Depending on the pulley size, they are made to use with P1, P2, Q1, or Q2 taper bushings, which we also stock. Most of our 5TB pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.
BKH Series Sheaves (1-Groove Cast Iron H-Bushed Pulleys)
BKH series bushed pulleys are manufactured for A, 4L, B, 5L, AX, BX, AA, and BB belts. BKH series pulleys range in diameter from 3.15″ to 18.75″ but custom ones are also available upon request. These pulleys use an H-style bushing, and this bushing type has a bore range of 3/8″ to 1-1/2″ and 10mm to 38mm. We stock a complete line of these bushings as well.
Types of V-Belt Pulleys
Several types of pulleys are used in v-belt transmissions, each with a different implementation. Occasionally flat-belt pulleys are suitable when the back side of the v-belt is used to rotate the pulley in the opposite direction of the driven pulley, as commonly employed with ribbed v-belts.
Standard pulleys have dimensions with one or multiple grooves, which mate with classic, small-engine, and hexagonal-style v-belts.
Companion pulleys contain integral spokes which run radially on the pulley. This produces a high strength-to-weight ratio advantageous to fractional horsepower pulleys.
Idler pulleys are used solely as belt tensioners in many v-belt drives but play an essential part in maintaining the tension required to drive the transmission. Idler pulleys reduce belt service life and the industry's efficiency. Still, they are necessary for messages where the drive must clear obstructions, or the driven pulley does not maintain a good arc of contact with the v-belt to transmit torque. Idlers can interact with either the wedged or flat side of the v-belt since no torque is required to be sent to this axle.
Variable speed pulleys have a variable pitch that adjusts the driven RPM, often within a range represented as a percentage. These pulleys are also helpful in maintaining belt tension for dynamic loads.
Step pulleys have two or more non-adjustable grooves with different pitches around the same shaft. These pulleys change the speed ratio of the transmission.
