For drives that run on 1/2" pitch chain, this single-strand sprocket with an integral hub gives you a direct shaft mount. MR supplies it in SAE 1045 steel, a medium-carbon grade suited to industrial duty. The part number to reference is MR-PINON-SIMPLE-1-2-Z33.
Reading the designation is straightforward: simplex means one row of teeth, 1/2" is the chain pitch, and Z33 is the tooth count. The hub is cast into the body, so the sprocket slides onto the shaft and is held by set screws or bolts rather than needing a separate bushing. Material is SAE 1045 steel.
You will find this size in chain drives on conveyors, bucket elevators, drag chains and handling equipment, as well as in agricultural machinery and in food and cement plants. Anywhere a defined ratio between driver and driven shaft is needed, a 33-tooth wheel on 1/2" pitch is a common choice. The hub keeps mounting simple on keyed shafts and shortens the time spent on assembly and later maintenance.
When specifying, confirm three things: chain pitch of 1/2", the 33-tooth count, and the shaft diameter the hub must fit. Check that the hub bore and fastening method match your shaft, then align the sprocket with the driven wheel. Misalignment shows up as noise and early wear. Correct chain tension and regular lubrication also keep the drive running quietly.
Other tooth counts and pitches are available. MR carries sprockets and chain wheels alongside a full power transmission range. To get an equivalent, send the part number MR-PINON-SIMPLE-1-2-Z33 or list what you need — pitch, teeth, material, hub type — and the team will quote the closest match.

Frequently asked questions
- What does simplex with hub mean on this sprocket?
- It has one row of teeth and a hub built into the body, so it mounts straight onto the shaft. That differs from a plate sprocket, which needs a separate hub or bushing to attach.
- What steel is it made from?
- SAE 1045, a medium-carbon steel with good mechanical strength and hardenability, which suits industrial drives where wear resistance matters.
- Can I get a different tooth count?
- Yes. MR supplies sprockets in various tooth counts and pitches. Send your specifications by WhatsApp or email and the team will quote the option that fits.
