MR Piñón simple 3/8" Z29 is a sprockets and gears reference, within Power transmission. Request a quote for Piñón simple 3/8" Z29 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

It is used to transmit motion between parallel shafts by means of a roller chain, in assemblies where a central hub is needed to secure the sprocket to the shaft with a key or screw. It is machined from SAE 1045 steel, a material suitable for continuous service with moderate loads. It is a replacement and project part, available to quote by WhatsApp.

The simplex sprocket 3/8" Z29 is a sprocket with a single row of teeth, with a central hub, that meshes with roller chains of 3/8" pitch. Its designation indicates 3/8" pitch and 29 teeth, and it is manufactured in SAE 1045 steel. The hub is the protruding central part that allows mounting on the shaft and securing by means of a key, set screw or screw. This type of sprocket differs from flat sprockets without a hub because it offers a larger contact surface with the shaft and better radial guidance.

Typical applications for a 3/8" pitch sprocket with 29 teeth include chain drives in low- and medium-power machines: light conveyors, small bucket elevators, mixers, packaging equipment, automatic gates and drive mechanisms in general. It is also used as a replacement sprocket in assemblies where a 3/8" pitch chain already exists and the original transmission ratio needs to be maintained or slightly modified.

To correctly select this sprocket, take into account the chain pitch (3/8"), the number of teeth (29) and the shaft diameter where it is mounted. The hub must have a bore compatible with the shaft and, if applicable, a keyway. Check the alignment between sprocket and chain: angular or radial misalignment accelerates wear on the teeth and chain. Proper lubrication and correct chain tension extend the service life of the assembly.

If you need a sprocket with a different number of teeth, another pitch or a hub of different dimensions, we can manufacture it or find an equivalent size. To do so, send us the part number MR-PINON-SIMPLE-3-8-Z29 or the data of the original sprocket (pitch, number of teeth, shaft diameter and type of fixing) by WhatsApp. With that information we will quote the part that best fits your machine.

If this sprocket is not exactly the one you are looking for, write to us on WhatsApp with the part number or the size and we will help you find the solution.
