Product Description

Guaranteed Quality American Standard 4B QD Bushed Sheaves Pulleys For A And B Belts

The 4B series pulleys are used for A, AX, AA, 4L, B, BX, BB, and 5L v-belts with diameters from 3.75 “to 38.35”. Depending on the pulley size, they can be used with SH, SD, SK, SF, or E QD bushings; we also have them in stock. Our 4 groove 4B QD bushing 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. The main advantage of using QD (quick detachable) pulleys is that if the bushing (hub) is damaged, the entire assembly does not need to be replaced, or if only the pulley is worn, the same principle applies. Another significant advantage is that QD pulleys have a more comprehensive range of hole options than the “fixed hole” type.

4B Style QD Bushed Pulley Size Chart

QD bushing pulley
The manufacturing tolerance of the QD bushing pulley is accurate. They have different diameters and can be statically or dynamically balanced. These pulleys are made of grey cast iron from GG 25 to GG 30. They have a strength of 207 Mpa and a hardness of 187 to 241.
One side of the QD housing has a fully split flange and a straight flange around the outside diameter. The flange fits closely and requires a hex head screw to install the component. When the screws are tightened, the flange compresses and draws the identification part on the bushing.
Why choose the QD bushing pulley?
The QD bushing pulley has many advantages over the traditional V-pulley. They are more cost-effective and ideal for use with non-critical ratio drives. It is characterized by a cylindrical CZPT with a radial shape, which can reduce friction in the hole and limit the movement of mechanical parts. They fit well with the hub in the sprocket.
Warehouse inventory
The warehouse covers an area of 5000 square meters and can provide various A/B/C/Z standard models with total quantities and a large inventory. At the same time, different non-standard customized drawings are accepted. The daily output is 10 tons, and the delivery time is short.
