4D Series Cast Iron QD Bushing Sheaves Pulley for “D” Belts

4D Series Cast Iron QD Bushing Sheaves Pulley for “D” Belts

4D series four-groove QD bushed sheaves(4D Series QD Bushing Sheaves) are manufactured for D-series classic v-belts and D-banded belts; they range from 12.64″ to 58.64″ in diameter. Depending on the sheave size, they are made to use an F, J, or M QD (quick detachable) bushings, which we also stock. Most of our 4D 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 D-Series, D-Series Banded V-Belts

(1) D-Series V-Belts

Classic D-Series V-Belts have a 1.25″ top-width, 0.75″ thickness, and a 40° angle. Additionally, D 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 D-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) D-Series Banded V-Belts

D-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. D-series v-belts have a 1-1/4″ 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.

V-belt Pulley American Standard — D Series

The American standard pulley is according to the American ANSI standard. Its primary material is gray iron, which is suitable for 2L, 3L, 4L, 5L, A, B, C, D, 3V, 5V, 8V belts, J, L, and M multi-ribbed belts. American standard pulley product types: AK, BK, TA, TB, TC, B, C, D, 3V, 5V, 8V, J, L, M, VP, VL, VM. Taper bushing pulleys are working with STB, QD, or TB taper bushings.

Features and Benefits

(1) The belt is an elastomer that can mitigate load impact and run smoothly without noise.
(2) Overload will cause the belt to slip on the wheel, thus playing the role of protecting the whole machine.
(3) The grooves of most American standard pulleys are suitable for several different belt types, and the belt design and application are relatively flexible.
(4) There are many types of American standard pulley grooves and taper bushings. Some pulleys and bushings are able to install on the front and back, which has become a solution for harsh conditions on different occasions.
(5) American standard pulleys and taper bushings can achieve precise balance control and perform well in transmission.
