This simplex sprocket from MR has a 1/2" pitch and 25 teeth (Z25). The integrated hub lets you mount it directly on a keyed shaft without extra adapters. Made from SAE 1045 steel, it balances strength with machinability if your assembly needs modifications. Use it wherever you need a fixed, dependable transmission ratio.
The sprocket's design includes a hub that simplifies installation on a shaft, secured with a set screw or key depending on your equipment. It is a general-purpose power transmission component for 1/2" pitch roller chains. The complete part designation is Simplex sprocket 1/2" Z25. SAE 1045 steel provides toughness and responds well to heat treatment.
You will find this sprocket in conveyors, bucket elevators, food processing transmission systems, packaging lines, and agricultural equipment. It also appears in mixers, agitators, and chemical industry machinery. In each case, the goal is positive, synchronized transmission with minimal chain and sprocket wear. The hub design makes it adaptable to various mounting arrangements.
When selecting this sprocket, confirm the chain pitch (1/2"), the tooth count (25), and your shaft diameter. The hub bore must match the shaft, and you may need to machine a keyway or threaded holes for your application. Check alignment between sprocket and chain and maintain proper tension to avoid premature wear. Consult our technical team if you plan to modify the bore.
If you need a different tooth count, pitch, or hub size, we can source it. MR can supply custom sprockets based on a sample or drawing. To request an equivalent, send the part number MR-PINON-SIMPLE-1-2-Z25 or a photo of the original part with key dimensions. That helps us identify the best match quickly.
