This simplex sprocket with hub is identified by its 1/2" pitch and 20 teeth (Z20). It is manufactured by EMMAR in SAE 1045 steel and supplied by MR Industrial Accessories LLC. The sprocket is intended for single-row chain drives that require a moderate speed ratio and dependable tooth engagement.
The part is a simplex sprocket, meaning it carries one row of teeth, and it includes a central hub for shaft mounting. The 1/2" pitch matches ANSI 40 chain, while the 20-tooth count sets the ratio when paired with another wheel. SAE 1045 carbon steel offers a balance of machinability and strength for the tooth profile, and it can be heat treated later if the application calls for it.
Common uses for a sprocket of this size include conveyors, elevators, mixers, mills, packaging lines and material handling equipment. It also appears in agricultural implements and factory machinery. Because the pitch is 1/2" and the tooth count is 20, it suits drives where an intermediate output speed and reasonable torque are needed.
When selecting this sprocket, check the chain pitch (1/2"), the number of teeth (20) and the shaft diameter at the mounting point. The hub can be secured with a key or a set screw, depending on the equipment design. Confirm that the sprocket and the mating wheel are aligned, that chain tension is correct and that lubrication is adequate. For high-speed or heavily loaded drives, consider heat treatment or a more wear-resistant material.
To find an equivalent, send the existing part number, the tooth count and the pitch. With those details we can confirm whether this 1/2" Z20 model is the right fit or suggest another option. We can also review variations in tooth count or hub style. Contact us by WhatsApp or email for a quote.

Frequently asked questions
- What does the 1/2" pitch mean on this sprocket?
- The 1/2" pitch is the distance between the centers of two consecutive teeth. It corresponds to ANSI 40 chain. The chain and sprocket must share the same pitch for proper engagement.
- How can I tell if this sprocket fits my machine?
- Check the chain pitch, the number of teeth and the shaft diameter. If your equipment uses a 1/2" chain and the original sprocket has 20 teeth, this model may be compatible. Send us your machine details and we can help confirm.
- Can I get a different tooth count or hub type?
- Yes. We supply sprockets with various tooth counts and hub configurations. Send the part number, the number of teeth and the pitch you need via WhatsApp or email, and we will quote the variant that fits.
