8V Series Cast Iron Four-Groove QD Sheaves for “8V” Belts

8V Series Cast Iron Four-Groove QD Sheaves for “8V” Belts

8V series four-groove QD (quick detachable) bushed sheaves(8V Series Four-Groove QD Sheaves) are manufactured for 8V and 8V banded belts. They range from 12.50″ to 53.00″ in diameter. Depending on the sheave size, they are made to use an F, J, or M QD bushing, which we also stock. Most of our four-groove 8V 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.

(1) 8V-Series V-Belts

Classic 8V-Series V-Belts have a 0.63″ top-width, 0.53″ thickness, and a 38° angle. Additionally, 8V 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 8V-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.

(2) 8V-Series Banded V-Belts

8V-series v-belts are a part of the “classic” lineup of v-belts because they are one of the oldest style belts used and one of the most common. Our belts are manufactured by ARPM standards and offer superior strength, durability, and performance. 8V-series v-belts have a 1.0″ top-width per belt (band/ rib).

Related 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 Assembly Precautions

1. Gasoline must be used for the last cleaning before assembly to ensure that all parts are clean and dry, the mating surfaces are tightly fitted and free of oil stains, and have sufficient friction.

2. The hexagon socket head cap bolts for assembly should also be washed with gasoline and dried before assembly. Do not apply lubricating oil or grease in the bolts or screw holes to ensure sufficient frictional self-locking ability after the bolts are tightened.

3. When the three hexagon socket head bolts are about to be installed, they need to be tightened in turns to ensure that the tapered sleeve is subjected to uniform axial force and that the v belt pulley and the tapered sleeve are well positioned coaxially.

4. Before installation, check and measure the length of the hexagonal socket head bolts for assembly to ensure that the assembly bolts can withstand the bottom end of the blind hole of the taper sleeve after tightening to ensure that the tapered surface fits tightly and to ensure that the bolts are subjected to the reverse thrust at the bottom of the blind hole, resulting in The anti-loosening effect of the double nut principle is the same.

5. After the pulley is tightened, check and adjust the relative position of the primary and driven pulley by pulling the wire to ensure that the two pulleys are on the same plane and the belt tension is moderate.

6. The pulley cover should be intact and installed firmly to ensure that the belt is broken or the pulley is loosened and withdrawn during operation, resulting in a significant safety accident.

7. The tapered sleeve is a vulnerable part. It should be checked before each assembly, and the spare parts should be replaced in time if any defects are found. After a long operation, the inner hole and the chain groove may be damaged. After a long process, the internal cavity and the chain groove may be damaged.
