3V series eight-groove taper bushed sheaves are manufactured for 3V, 3VX, banded 3V, and banded 3VX belts. They range from 4.75" to 33.50" in diameter. Depending on the sheave size, they are made to use a Q2, R1, or S1 split-taper bushing, which we also stock. Most of our eight-groove 3V split taper 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.

Experienced Workers Packing Pulleys Carefully, safe wooden cases keep parts from being injured or damaged during sea or air shipment.

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 lining 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.
