This simplex sprocket with hub, 3/4" pitch and 25 teeth, is a chain wheel that MR Accesorios Industriales supplies. It is used to transmit motion between parallel shafts in 3/4" pitch roller chains. Its hub allows direct mounting on the shaft, with keyway or set screw as applicable. Made of SAE 1045 steel, it resists the wear typical of power transmission and can be machined to suit your assembly.

The simplex sprocket 3/4" Z25 has 25 teeth, 3/4" pitch and is made of SAE 1045 steel. It is a simplex sprocket with hub, meaning the hub protrudes from the toothed disc and allows it to be fixed to the shaft with a larger contact surface. The designation Z25 indicates the number of teeth, a key data point for calculating the transmission ratio together with the driven wheel. This type of sprocket is used with 3/4" pitch roller chains and is mounted on shafts rotating at medium speeds.

Typical applications include chain drives in agricultural machinery, conveyors, bucket elevators, mills, mixers and power transmission equipment in general. It is also used in gearboxes and mechanisms where a specific transmission ratio is required. As a part that MR supplies, machining can be evaluated according to the equipment requirements, provided the base geometry of 25 teeth and 3/4" pitch is used.

To correctly select this sprocket, take into account the chain pitch (3/4"), the number of teeth (25) and the shaft diameter where it is mounted. The hub allows it to be fixed with a key, set screw or both, depending on the torque to be transmitted. Check the alignment between sprocket and wheel to avoid premature wear. If you need a different ratio, you can combine this sprocket with wheels of other diameters within the same pitch.
