This plain sprocket with hub is manufactured by EMMAR in SAE 1045 steel. It has a 3/4" pitch and 39 teeth, and it mounts on a shaft to mesh with a 3/4" pitch chain. The hub is the raised central section that provides room for the fastening system, whether a key or a set screw, depending on how the equipment is built.
The 3/4" pitch refers to the distance between the chain roller axes. With 39 teeth, the sprocket delivers a transmission ratio that balances speed and torque for medium-load drives. SAE 1045 steel gives the teeth good wear resistance and toughness for continuous operation. The teeth are machined for even meshing and uniform wear.
You will find this sprocket in chain conveyors, bucket elevators, mills, mixers and agricultural machinery. In these systems it transfers motion from the drive or driven shaft, and the hub simplifies mounting and alignment. It is a common choice on production lines that need a specific ratio and a component that can be replaced without altering the rest of the assembly.
When selecting, confirm that the chain pitch matches 3/4" and that 39 teeth suit your desired ratio. The hub must fit the shaft diameter and accept the fastening method used in your design. During installation, align the sprocket with the chain wheel to prevent irregular wear and noise. Keeping the chain properly lubricated helps extend the life of the teeth.
If you need a different tooth count, pitch or hub size, we can manufacture it or locate an equivalent. Send the current part number, number of teeth, pitch and shaft dimensions. With that information we can quote the most suitable option and advise you on chain compatibility.
