The simplex sprocket 3/8" Z57 is a sprocket supplied by MR Accesorios Industriales, designed to transmit motion in 3/8" pitch chains. Its hub allows it to be mounted directly on the shaft with the appropriate fixing, without the need for additional adapters. It is used in equipment where a specific transmission ratio and smooth running are required. If you need a different size, we can look into supplying a variant.

This sprocket has 3/8" pitch, 57 teeth and is made of SAE 1045 steel. The designation Simplex sprocket 3/8" Z57 indicates that it is single row, with hub, and that its number of teeth is 57. The 3/8" pitch corresponds to chains of that same pitch, so the toothing must match exactly for correct meshing. The hub is the central part that allows mounting on the shaft and usually has a hole with keyway, although the final dimensions are confirmed against the drawing or the technical data sheet.

It is used in chain drives of agricultural machinery, conveyors, lifting equipment and transmission systems in general. It is commonly found in applications where speed needs to be reduced or increased between shafts, or where a particular transmission ratio is required. It is also used in machine tools and material handling equipment. Being SAE 1045 steel, it offers a good combination of strength and machinability, suitable for moderate loads and medium speeds.

To select the correct sprocket, take into account the chain pitch, the number of teeth, the shaft diameter and the type of fixing. Verify that the pitch matches that of the existing chain; a different pitch prevents meshing. The number of teeth defines the transmission ratio and affects speed and torque. The hub must have a hole and keyway compatible with the shaft. If the sprocket works in an environment with dust or dirt, consider adequate lubrication and periodic wear inspection.

If you need a sprocket with another number of teeth, another pitch or a hub with special dimensions, we can supply it. MR Accesorios Industriales has machining capacity to develop custom parts.
