Product Description

American Standard Cast Iron Six-Groove QD Sheaves For 3V Belts

3V series six groove QD (quick removal) bushing block applies to 3V, 3VX, 3V belt, and 3VX belt. Their diameters range from 4.75 inches to 33.50 inches. Depending on pulley size, they use SK, SF, or E QD bushings, which we also have in stock. Our six-groove 3V QD pulley is mainly made of high-strength 35 cast iron, coated with phosphate and anti-corrosion paint. All these are balanced at the factory to ensure the machine's smooth operation.

 Match 3V, 3VX series V belt
(1) 3V series deep wedge V-belt
The classic 3V series V-belt has a top width of 0.38 ", a thickness of 0.31", and an angle of 38 °, which also classifies it as a deep wedge V-belt. The 3V series belts are more compact and powerful than the standard 40 ° angle v-belts. Because of their long-term success and economical operation, they are also one of the industry's most widely used belt series. The high-quality 3V series v-belts we provide are manufactured according to ISO 9001 and ARPM standards; They are oil and heat-resistant and can be directly interchanged with other brands. The 3V conveyor belt is made of natural rubber compound and polyester rope, covered with a cotton and polyester mixture and is highly durable. The 3V series belts are used with HVAC, lawn and garden equipment, and agricultural equipment for most general heavy industrial applications. We also stock a complete set of high-power v-belts and matching v-pulleys/pulleys.
(2) 3VX toothed V-belt
The top width of the 3VX toothed v-belt is 0.38 ", and the thickness is 0.31". Our grooved 3VX v-belts are manufactured with rough sidewalls to eliminate slip, improve efficiency and save operating costs. They are also manufactured according to ARPM standards and are oil and heat-resistant. The 3VX conveyor belt comprises high-quality neoprene compound and high-strength polyester rope, and the top fabric is made of a cotton polyester blend. In addition to performance, durability, and energy conservation advantages, our v-belts will be used with existing v-pulleys/pulleys.
(3) 3V series ribbon V-belt
The 3V series v-belts are part of the "classic" v-belt series because they are one of the oldest and most common styles. Our belts are manufactured according to ARPM standards and have excellent strength, durability, and performance. The top width of each belt (belt/rib) of the 3V series v-belt is 0.38 inches.
(4) 3VX toothed V-belt
All our v-belts are manufactured according to ARPM specifications, with excellent performance and durability. All our v-belts are manufactured according to ARPM specifications, with excellent performance and durability. Because of its design, the belt 3VX toothed v-belt runs more smoothly and loosely and is generally more durable than the standard belt C v-belt. They also provide higher efficiency than ordinary v-belts, which means fewer energy costs.
Whether the pulley rust affects the use?
Friends who often use pulleys know that pulleys, as cast iron parts, are relatively easy to rust. At this time, many friends asked me, will the rest of the pulley affect the use? Will rust on the pulley surface accelerate the belt to wear? For this problem, I can tell you that the pulley surface's rust will not affect the use nor accelerate the wear of the belt.
As long as you pay attention to the observation, you will find that with frequent use, the belt groove of the belt pulley will become brighter and brighter, and the belt only contacts the belt groove of the belt pulley. Of course, the rust on the surface of the v-belt pulley has nothing to do with the wear of the belt.
Causes of pulley wear:
1. The belt is usually worn and has a service life. Regularly check and replace the use of the belt.
2. The quality of the pulley, such as the trachoma, will affect the belt.
3. Installation problem: improper engine pulley and belt installation will also affect the belt.
4. Working environment problem: due to poor working conditions, local pulley runout, or abnormal operation, it needs to be repaired.
Rust removal and rust prevention methods for pulley: mainly include physical and chemical methods. The anti-rust process is to increase the protective layer and isolation layer.
1. Physical methods include: manual rust removal, mechanical rust prevention, shot blasting, sandblasting, etc.: rust removal mainly adopts physical methods such as collision, knocking, shoveling, grinding, scraping, etc. The belt grooves of ordinary pulleys become brighter and brighter, which is physical rust removal.
2. Chemical treatment method: chemical treatment method is called the acid washing method. Hydrogen generated by metal action will cause mechanical peeling of the oxide skin
3. There are many ways to prevent the pulley from rusting. Standard methods include oiling, blackening, phosphating, and blackening the pulley and painting to prevent the pulley from rusting.
