A 3/4" pitch simplex sprocket with 38 teeth, supplied by MR Industrial Accessories for chain drive lines that need a defined transmission ratio. The hub mounts straight onto a compatible shaft and is locked with a key and set screw, so no adapter is required. It is built in SAE 1045 steel.

Reading the designation is straightforward: simplex means a single strand, 3/4" is the chain pitch, and Z38 is the tooth count. The body is SAE 1045 steel, which gives a workable balance of hardness and toughness for industrial power transmission. The hub lets the sprocket sit directly on the shaft and be secured with a key and set screw.

Typical installations are 3/4" pitch chain drives on conveyors, elevators, agricultural equipment and process machinery, including gearboxes and drive systems where a 38-tooth sprocket runs with a standard chain of that pitch.

Selection comes down to three checks. Confirm the chain pitch is 3/4". Confirm 38 teeth give the transmission ratio you want. Confirm the hub bore suits your shaft; if it does not, the hub can be machined or adapted with a bushing. Shaft-to-sprocket alignment also matters, since misalignment accelerates wear on both the sprocket and the chain.

Other tooth counts, pitches and hub dimensions can be sourced on request. MR Industrial Accessories also supplies mounted units and housings, chains, sheaves, belts, couplings, bearings, seals, lubrication and maintenance tools, and serves customers in the United States and Latin America.
