The double sprocket 3/4" Z13 is a chain wheel supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. It has 13 teeth and a double row of teeth with a central hub, which allows it to be mounted on shafts and coupled to double-row chains. It is used in power transmission equipment where robustness and precise alignment are required. If you need a different size, a variant within the same series can be quoted.

This item is a double sprocket with hub of 3/4" pitch, with 13 teeth and manufactured in SAE 1045 steel. The full designation is Double sprocket 3/4" Z13. The central hub allows it to be fixed to the shaft, and the double toothing makes it suitable for double-row chains. The 3/4" pitch defines the distance between chain pins; therefore, when replacing it, that pitch and the number of teeth must be respected so as not to change the transmission ratio.

It is used in chain drives of agricultural machinery, conveyors, elevators, mills and material handling equipment. It also appears in power transmission systems where a sprocket with a hub is required to mount on shafts of considerable diameter. Due to its construction in SAE 1045 steel, it is suitable for continuous service with moderate to high loads, provided that mounting and lubrication are correct.

To select it, verify that the chain pitch is 3/4" and that the number of teeth matches that of the original sprocket. Check the shaft diameter and the hub fastening system, and check the alignment between sprocket and chain. Poor alignment accelerates wear on teeth and chain. If the sprocket works in an environment with dust or dirt, adequate lubrication and periodic wear inspection should be provided for.

If you cannot find the exact part number or need a nearby size, send us the data of the original sprocket: pitch, number of teeth, hub type and shaft diameter. With that information we can look for an equivalent within the line supplied by MR or evaluate the manufacture of a similar part. We can also guide you if the sprocket is part of an assembly with a chain and you need to replace both components.
