3V series five 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 SDS, SK, SF, or E QD bushings, which we also have in stock. Our five-groove 3V QD pulley is mainly made of high-strength grade 35 cast iron, coated with phosphate and anti-corrosion paint. All these are balanced at the factory to ensure the machine's smooth operation.

 Support the use of 3V, 3VX series V-belts
(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) 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.
(3) 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 is composed of 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 also be used with existing vertical pulleys/pulleys.
(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.
The daily inspection of pulley depends on these three aspects
The pulley is a worn part that often shakes and slips during long-term operation. If the belt pulley is not checked regularly, the machine will also be damaged for a long time and may be directly damaged in severe cases. Therefore, in daily use, we should check the pulley regularly. What aspects of pulleys should be reviewed?
Check the pulley in three aspects every day:
1. Pulley surface: all standard pulleys shall be weighed according to the standard. If the pulley surface is convex, observe whether the pulley shakes during operation. In case of vibration, the pulley must be replaced in time
2. Belt pulley: The belt pulley is driven by the belt, so we also need to check the belt regularly. After installation, we should first observe the tightness of the belt. If the building is too tight, the speed of the pulley will be affected. In severe cases, the motor shaft may be worn. If the installation is too loose, it may reduce the machine's working efficiency and cause slipping. If the belt is aged and the tension is low, we need to replace the belt in time.
3. Belt pulley mounting hole: the mounting hole of the belt pulley is in direct contact with the motor shaft, which is also an important part of determining whether the machine can operate. We need to regularly observe whether the mounting hole is clean and whether there are impurities in it. Because contaminants may damage the mounting hole, the pulley will not be used if the mounting hole is damaged.
