5V series six groove QD (quick disassembly) bushing pulley applies to 5V, 5VX, 5V belts, and 5VX belts. They range in diameter from 4.40 "to 50.00". Depending on pulley size, they use SD, SK, SF, E, F, or J QD bushings, which we also have in stock. Our six groove 5V QD pulley is mainly made of high-strength 35-grade cast iron, coated with phosphate and anti-corrosion paint. All these are balanced at the factory to ensure the smooth operation of the machine.

Relevant supporting 5V, 5VX series V-belts
(1) 5V series V-belt
Classic 5V series V-belts have a top width of 0.63 ", a thickness of 0.53", and an angle of 38 °. In addition, the 5V V-belt is one of the oldest V-belts in the industry. 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 5V series v-belts we provide are manufactured according to ISO 9001 specifications. They are oil and heat-resistant and can be directly interchanged with other brands. They are composed of natural rubber compound and polyester rope, covered with a mixture of cotton and polyester, and have high durability. 5V series belts are used with HVAC, lawn and garden equipment, and agricultural equipment for most general heavy industrial applications.
(2) 5VX toothed V-belt
The top width of the 5VX toothed v-belt is 0.53 ", and the thickness is 0.53". Our grooved 5VX 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 5VX 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 also be used with existing vertical pulleys/pulleys. Please contact us to get the quotation for a 5VX toothed v-belt or pulley, and we will be happy to help you.
(3) 5V series ribbon V-belt
The 5V series V-belts are part of the "classic" V-belt series because they are one of the oldest and most common belts. Our belts are manufactured according to ARPM standards and have excellent strength, durability, and performance. The top width of each 5V series v-belt (belt/rib) is 0.63 ".
(4) 5VX toothed V-belt
All our v-belts are manufactured according to ARPM specifications, with excellent performance and durability. Because of its design, the belt 5VX toothed v-belt runs more smoothly is more relaxed 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. We can also stock pulleys/pulleys for 5VX belts.
QD sleeve | quick disconnect sleeve
QD bushings are used for various sprockets, pulleys, and synchronous drives in industrial power transmission and agricultural industries. They are designed for easy installation and unloading; They are also referred to as quick disconnect bushings. The QD sleeve facilitates standard installation outside the flange, reverse installation on the inside, and utilizes a single split that extends to the entire sleeve length. Our QD bushing can be interchanged with other brands and is made of high-grade steel by precision machining, which is suitable for perfect installation. The advantages of QD casing compared with different types of casing include: Easy to install/unload, firm grip, and high strength. We stock all standard-size QD bushings and provide custom QD bushings (including stainless steel bushings) upon request. QD casing is the most widely used in the world; Please contact our customer service team immediately for a quote or other information on quality QD casing.

Features of tapered bushing pulley
The tapered bushing pulley is a mechanical connection. The tapered sleeve is inserted between the mounting shaft and the pulley. The belt pulley is self-locking on the pointed sleeve through the socket head cap screw, and the tapered sleeve tightly fixes the mounting shaft. The tapered sleeve is mainly divided into TB taper sleeve and QD taper sleeve. The fitting hole of the tapered sleeve and the pulley is half-sided. Two small holes on the tapered sleeve and two threaded holes on the pulley form a complete hole. The threaded hole in the tapered sleeve and the smooth hole in the pulley form a complete fixture. During assembly, place two screws in the two threaded holes of the pulley. As the screw continues to tighten in the threaded hole of the pulley, the thread action pushes the screw to the small end of the tapered hole. The conical sleeve is the two incompletely machined holes of the screw, so when the screw head contacts the bottom of the suction pipe hole, the force will be transferred to the conical sleeve. The tapered sleeve moves to the small end of the tapered hole relative to the pulley. Because of the taper, the tapered sleeve will continue to wind the shaft, and the column will react to the tapered sleeve and then act on the pulley. This way, the pulley, tapered sleeve, and shaft are fitted tightly.
