5V Series Cast Iron Three-Groove QD Sheaves for “5V” Belts

5V Series Cast Iron Three-Groove QD Sheaves for “5V” Belts

5V series three-groove QD (quick detachable) bushed sheaves are manufactured for 5V, 5VX, banded 5V, and banded 5VX belts. They range from 4.40″ to 50.00″ in diameter. Depending on the sheave size, they are made to use an SDS, SK, SF, E, or F QD bushing, which we also stock. Most of our three-groove 5V QD sheaves 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.

Related Matching 5V, 5VX Series V-Belt

(1) 5V-Series V-Belts

Classic 5V-Series V-Belts have a 0.63″ top-width, 0.53″ thickness, and a 38° angle. Additionally, 5V V-belts are one of the oldest styles of 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 premium 5V-series v-belts we supply are manufactured under ISO 9001 specifications, are oil and heat resistant, and directly interchange with other brands. They are constructed of a natural rubber compound with polyester cords and use cotton with a polyester blend cover for high durability. 5V series belts are used in most general heavy-duty industrial applications along with Heating, ventilation, air conditioning (HVAC), lawn and garden equipment, and agricultural equipment.

(2) 5VX Cogged V-Belts

5VX cogged v-belts are designated by having a 0.53″ top-width and 0.53″ thickness. Our cogged 5VX v-belts are manufactured with raw-edge sidewalls to eliminate slippage and increase efficacy, saving operation costs. They are also manufactured by ARPM standards and are oil and heat-resistant. 5VX belts are constructed from a high-quality chloroprene compound with high-strength polyester chords and have a top fabric built from a cotton polyester blend. Besides the performance, durability, and energy savings benefits, our cogged v-belts will work with existing stand pulleys/ sheaves. Please contact us for a quote on 5VX cogged v-belts or pulleys, and we will be happy to assist you.

QD Bushings | Quick Disconnect Bushings

QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings.

QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings’ benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths.

We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones. QD bushings are found in some of the most rugged applications worldwide; contact our customer service team today for a quote or additional information on our premium QD bushings.

Pulley Installation Method:

1. Check the pulley grooves to make sure there are no scratches or sharp edges and all dimensions are up to standard;
2. Clean the surfaces of all parts, such as hub holes, taper sleeves, bolt holes, etc. Fit the cone sleeve into the pulley, aligning all the screw holes.
3. Apply oil to the screw (TB1008-TB3030) and thread (TB3525-TB5050) and screw them into the mounting holes, but do not tighten them yet.
4. Clean the surface of the drive shaft, push the pulley with the tapered sleeve installed to the predetermined position on the shaft, and check whether the v belt pulleys are alignning.
5. When using the keyway, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub.
6. Using a hexagonal wrench conforming to the DIN911 standard, alternately, gradually, and evenly tighten the bolts in each mounting hole until the torque shown in the table below is reached.
7. After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts and retighten them if necessary.
8. To prevent the intrusion of foreign matter, fill the hole’s connection hole with grease.

Pulley Removal Method:

1. Loosen all the bolts, take out one or two of the bolts according to the number of disassembly holes, lubricate the bolt pattern and the tip of the bolt with oil, and insert the bolt into the disassembly hole.
2. Tighten the bolts alternately until the taper sleeve and pulley are loosenning.
3. Remove the taper sleeve and pulley from the shaft.
