The double sprocket with hub, 3/4" pitch and 76 teeth is a chain drive sprocket supplied by MR in SAE 1045 steel. It is used to drive machine shafts in reduction ratios where a wear-resistant toothing and a hub that allows direct mounting on the shaft are required. Its double construction provides rigidity and alignment during assembly.

This item is a double sprocket with hub, 3/4" pitch, 76 teeth, SAE 1045 steel material. The commercial designation is Double sprocket 3/4" Z76. The 3/4" pitch corresponds to roller chains of that pitch, and the 76 teeth define the transmission ratio when combined with another sprocket of the same pitch. The hub allows mounting on the shaft with a key or set screw, depending on the equipment design.

It is used in low-speed, high-torque drives: chain conveyors, bucket elevators, cement, mining, food and woodworking machinery. Also in material handling equipment where a significant reduction with a 3/4" pitch chain is required. It is common in applications where the sprocket is mounted on a keyed shaft and a locally sourced sprocket is needed.

To select correctly, check the chain pitch (3/4"), the number of teeth (76) and the shaft diameter where the hub is mounted. Also check the fastening type: key, set screw or flange. During assembly, align the sprockets and tension the chain according to the equipment manufacturer's recommendations. Proper lubrication and wear monitoring extend the service life of the assembly.

If you need a sprocket with a different number of teeth, another pitch or a different hub, we can source it.
