A 3/4" pitch chain drive needs a wheel that carries two rows of teeth on a single hub. This double sprocket, identified as Z13, has 13 teeth and is produced in SAE 1045 steel. It is supplied by MR Industrial Accessories for transmission assemblies that call for a hub-mounted sprocket.
The code tells you most of what you need: 3/4" is the chain pitch, Z13 is the tooth count, and "double" means two rows of teeth on one body. A hub sits at the center so the part can be fixed onto a shaft. Pitch is the pin-to-pin distance of the chain, so a replacement has to match both that figure and the 13 teeth to keep the drive ratio unchanged.
You will find this type of sprocket on conveyors, elevators, mills, agricultural implements and other material handling equipment. It also fits transmission layouts where the shaft is large enough to require a hub instead of a plain plate sprocket. SAE 1045 steel suits continuous duty at moderate to high load when the mounting is true and lubrication is maintained.
Before ordering, confirm the chain pitch is 3/4", count the teeth on the worn part, and measure the shaft and hub fixing. Line up sprocket and chain carefully; misalignment is a common cause of tooth and chain wear. In dusty or dirty areas, keep lubrication on schedule and inspect the teeth periodically for wear.
Send the details of the part you are replacing: pitch, tooth count, hub style and shaft diameter. From there we can search the line for a match or review making a similar part. If the sprocket runs with a chain that is also due for replacement, we can help you sort out both items together.

Frequently asked questions
- What does "double sprocket with hub" describe?
- It has two rows of teeth plus a central hub. The two rows let it run with a double-row chain, and the hub gives you a surface to fix and adjust the part on the shaft.
- What steel is used for this sprocket?
- SAE 1045 carbon steel. It is a common choice for transmission components because it machines well and holds up mechanically when mounting and lubrication are handled correctly.
- How do I ask for a different size or an equivalent?
- Send the part number by WhatsApp along with the pitch, tooth count, hub style and shaft diameter of the original. We then check whether a variant exists in the series or whether a similar part should be made.
