The double sprocket 5/8" Z21 is a chain wheel supplied by MR Accesorios Industriales, designed to transmit motion in 5/8" pitch chains. Its hub design allows it to be mounted on shafts and secured with screws, which simplifies assembly and maintenance. It is used in conveyors, agricultural machinery and power transmission equipment that need two chain rings on a single body.

This sprocket has a 5/8" pitch, 21 teeth and is machined in SAE 1045 steel. It is a double type with hub: two chain rings integral to a central hub that mounts on the shaft. This configuration allows transmitting motion to two chains or doubling traction at a single point without adding parts. The hub makes anchoring and axial adjustment easier, and the SAE 1045 steel gives it the strength needed for continuous service.

Typical applications include chain conveyors, bucket elevators, seeders and combine harvesters, and transmission systems in processing plants. It is also used in road machinery and material handling equipment where a simple reduction with two outputs is required. As it is supplied by MR, it can be adapted to different shaft and mounting configurations according to the equipment's needs.

To select correctly, verify that the chain pitch matches the 5/8" and that the number of teeth is suitable for the desired transmission ratio. Check the shaft diameter and the hub mounting system. During assembly, align the chain rings and check chain tension to avoid premature wear. If the equipment works with variable loads, consider a steel with additional treatment.

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