This 45-tooth simplex sprocket runs on 3/8" pitch chain and comes with an integral hub, so it mounts straight onto a shaft and holds torque without extra adapter parts. It is machined from SAE 1045 steel, a grade chosen for the mechanical demands of everyday drive duty.

Reading the designation is straightforward: simplex means a single strand of chain, 3/8" is the chain pitch, and Z45 is the tooth count. The hub is part of the same piece as the toothed plate, which keeps the sprocket centered on the shaft and gives the fastening point for the key and set screw.

Typical installations include conveyors, elevators, machine tools, agricultural implements and general drive trains. A 3/8" pitch suits medium-load transmission, so this sprocket is a practical replacement for a worn unit or a component for a new build.

Before ordering, confirm three things: the chain pitch is 3/8", 45 teeth gives the ratio your drive needs, and the hub bore and fastening method match the shaft. Also check clearance around the sprocket and alignment with the other components in the drive. Poor alignment or a mismatched bore leads to early wear.

If your application calls for another tooth count, pitch or hub configuration, send the part number or the specifications and the team can point you to a suitable equivalent. Quotes are handled by WhatsApp or email, and the reply usually comes back quickly.
