3V series double groove QD (quick removal) bushing block applies to 3V, 3VX, 3V belt, and 3VX belt. Their diameters range from 2.20 inches to 25.00 inches. Depending on the pulley size, they use JA, SH, SDS, SK, or SF QD bushings, which we also have in stock. Most of our double groove 3V QD pulleys are 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.

Double-Groove 3V QD Sheave Size Chart  

(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 also be used with existing vertical 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.
Related QD Bushings | Quick Disconnect Bushings
QD bushings are widely used in industrial power transmission and agricultural markets for multi-sprocket, pulley, pulley, and synchronous transmission. They can be used for quick setup and simple uninstallation; They are also referred to as quick disconnect bushings. QD bushings can be routinely installed by all flange outboard and reverse mounting, regardless of the flange position on the inboard side, and use a single opening that extends over the entire bushing length. Our QD bushings are interchangeable with other brands and are made of high-grade steel and precision machined for optimum applications. The positive aspects of QD casing relative to its unique style include: It is easy to install/uninstall and has high retention energy and strength. We stock all standard sizes of QD bushings and provide custom QD bushings and stainless steel on request. QD casing is the most widely used in the world; These days, please contact our customer service personnel for any quotation or other information about high-quality QD casing.
Details to be noted when replacing the pulley
When the production equipment is used for a long time, its parts will inevitably wear and must be replaced. When replacing the European standard conical sleeve pulley, use a suitable Allen key to remove the locking screw. Then, screw the removed screw into the removal hole to separate the pulley and conical sleeve. If the tapered sleeve cannot be removed from the shaft, tap lightly with a rubber tool to separate the tapered sleeve from the steering column. In addition, what details should be paid attention to when replacing the pulley?
Details to be noted when replacing the pulley:
1. When replacing the belt pulley, first ensure that the surface of the belt pulley is not damaged, and apply lubricating oil on the shaft hole to facilitate faster removal of the belt pulley, so as not to affect subsequent use;
2. When installing the tapered sleeve as the belt pulley, pay attention to the self-locking method of the screw, and do not use a hammer or other tools for installation.
3. Screw the bolt out of the fastening hole and into the removal hole simultaneously. At this time, pressure must be applied to the bolts simultaneously. The pulley will fall off the conical sleeve when the removal holes are stressed simultaneously. The pulley has been removed.
4. Put the belt pulley into the shaft, insert the conical sleeve into the column keyway to adjust the position, install the belt pulley into the conical sleeve, and then screw the bolt into the fastening hole. When the pulley is offset, the bolt can be used to enter the removal hole for adjustment. After adjustment, install the pulley. The keyway should be fully tightened in the shaft groove. The key and the track will be damaged if it is too fast or too loose. If it is too loose, the belt will slip or vibrate. Therefore, when selecting the model, please contact the technician immediately for verification.
