MR Piñón doble 3/8" Z13 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" Z13 and any equivalents.

This double-row sprocket with hub is supplied by MR and made from SAE 1045 steel. It runs on 3/8" pitch chain and carries 13 teeth, so it drives two parallel chains from one shaft. That setup is common on conveyors, elevators and compact transmission machines. The hub mounts straight onto the shaft with a key and screw, so no extra bushing is needed. For a replacement or an adaptation, send the code and we will quote.

The part is a double sprocket with hub, 3/8" pitch, 13 teeth, in SAE 1045 steel. Read the designation as follows: 3/8" is the chain pitch, Z13 is the tooth count, and double means two rows of teeth on a single hub. SAE 1045 is a carbon steel that machines well and offers good strength, which suits tooth cutting and later heat treatment if the application calls for it. The hub is built in, so the sprocket mounts on the shaft and transmits torque without intermediate parts.

Use it where two chain lines must run in parallel. Roller conveyors, bucket elevators, packaging machines and compact transmission equipment are typical examples. It also fits power distribution systems where one shaft has to drive two synchronized chains. With 3/8" pitch and 13 teeth, it suits low and medium speed drives with moderate loads, where you need a specific ratio without making the assembly larger.

When selecting, confirm the chain pitch is 3/8" and the tooth count gives the ratio you want. Check the shaft diameter and how the hub will be fastened. Make sure the sprocket and chain align correctly to prevent early wear. If the original part has heat treatment or special tolerances, note that when you request the quote so custom manufacturing can be evaluated.

If you need an equivalent, such as a different tooth count or pitch, send the current code and your shaft measurements. With that information we can offer an alternative from our line or evaluate special manufacturing. We can also advise on the steel type and treatment for the load and speed of your equipment.
