The double sprocket with hub, 3/4" pitch and 76 teeth is a chain drive sprocket sold by MR in SAE 1045 steel. It is used to drive machine shafts in reduction ratios where a durable tooth profile and a hub that allows direct mounting to 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 3/4" pitch chain is required. It is common in applications where the sprocket is mounted on a keyed shaft and a domestically supplied 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 type of fastening: 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. MR Accesorios Industriales SRL sells split plummer block housings, ANSI chains and pulleys (sheaves), as well as bearings and power transmission. To request an equivalent, send us the code MR-PINON-DOBLE-3-4-Z76 or the shaft and chain dimensions.

Frequently Asked Questions

What does double with hub mean?
The term double with hub means the sprocket has two toothed rings integral with a central hub. That hub is the part mounted on the shaft, with a keyway or set screw, and it provides greater rigidity and transmission capacity than a single sprocket.
Can I order it with a different number of teeth?
Yes. As it is sold by MR, we can source 3/4" pitch sprockets with different numbers of teeth and hub types. Send us the current code and the dimensions you need on WhatsApp, and we will quote the variant.
How do I know if it is compatible with my chain?
The pitch must match: this sprocket is for 3/4" pitch chain. Also check the number of teeth and the shaft diameter. If you have any doubts, send us the chain and shaft data and we will advise you.
