MR Piñón doble 3/8" Z31 belongs to sprockets and gears, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for Piñón doble 3/8" Z31 and any equivalents.
This double sprocket with hub is designed for 3/8" pitch chains and has 31 teeth. It is made of SAE 1045 steel. The double-row configuration with a central hub allows two chains to run side by side or to drive two shafts that are close together. It is a practical choice for systems that need two transmission lines in a compact space.
The part number Z31 tells you the tooth count: 31. The 3/8" pitch matches ASA 35 chain, so confirm that your chain is the same series before ordering. The hub accepts a shaft and keyway, so check those dimensions against your application. The SAE 1045 steel body provides a stable base for the two chain rings.
You will find this sprocket in agricultural equipment, roller and belt conveyors, packaging lines, and production machinery where motion has to be duplicated. It also works in implements that use two synchronized chains, such as seeders and harvesters, and in some lifting mechanisms. It handles moderate loads at medium speeds.
During installation, align both chain rings with their respective chains. Misalignment is a common cause of uneven wear. Also verify that the shaft diameter and keyway fit the hub. If you change the number of teeth, the ratio and output speed change, so keep that in mind when selecting a replacement.
If you do not have the exact part number, send us the pitch, tooth count, hub type, and material of the original sprocket. Our team can identify the part or suggest a suitable equivalent from our supply line. We can also advise on chain lubrication and tensioning to help the assembly last longer.

Frequently asked questions
- Will this sprocket work with my 3/8" pitch chain?
- Yes, it is made for 3/8" pitch chains. Check that your chain matches this pitch; if not, it will not mesh. If you are unsure, send us your chain part number.
- What is the material and hardness?
- It is SAE 1045 steel. Hardness depends on heat treatment, which we can specify based on your needs. By default, it comes without hardening, but we can evaluate additional treatment for more wear resistance.
- Can I get a different tooth count or pitch?
- Yes, we supply sprockets in various configurations. If you need another tooth count or pitch, send us the details and we will quote you. We can also source special parts made to drawing.
