The double sprocket 3/4" Z29 is a toothed wheel supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. Its double-row design with hub allows mounting on shafts and coupling to different transmission elements. It is used in production lines, conveyors and equipment where reliable speed reduction or multiplication is required. As a product we supply, you can ask about variants and nearby sizes.
This item is a double sprocket with hub with 3/4" pitch and 29 teeth, made of SAE 1045 steel. The designation Double sprocket 3/4" Z29 indicates the number of teeth and the pitch of the chain it meshes with. The hub is the central part that allows mounting on the shaft, and being double means two toothed rings aligned to work with parallel chains or to duplicate the transmission. It is a solid part, machined to withstand power transmission loads.
Typical applications of this sprocket include chain conveyors, assembly lines, machine tools and movement equipment in industrial plants. It is also found in lifting systems and agricultural machinery drives. Being made of SAE 1045 steel, it offers good wear and fatigue resistance, making it suitable for continuous duty with proper lubrication. It is an alternative to replace worn sprockets or to build a new transmission.
To correctly select this sprocket, take into account the chain pitch (3/4"), the number of teeth (29) and the shaft diameter where it is mounted, which must match the hub bore. Also check the type of fastening (keyway, set screw or taper bushing) according to your equipment design. During assembly, make sure to align the rings with the chains and maintain adequate tension to avoid premature wear. Periodic lubrication and concentricity checks extend the service life of the assembly.
If you need an equivalent or a nearby size, you can request it with the part number MR-PINON-DOBLE-3-4-Z29 or by indicating the characteristics: pitch, number of teeth, hub type and material. As a product that MR supplies, we evaluate the feasibility of obtaining variants with other shaft diameters, number of teeth or surface treatments. We can also advise you if your application requires a single sprocket instead of a double one, or if you need to modify the hub bore.

Frequently Asked Questions
- What does double with hub mean?
- It means it has two toothed rings mounted on a central hub. The hub is the body that is fixed to the shaft, and the two rings allow transmitting motion to two parallel chains or duplicating the transmission. It is a robust configuration for applications requiring greater pulling capacity.
- Can I order this sprocket with another shaft diameter?
- Yes, as a product that MR supplies, we can evaluate obtaining the hub with the bore you need. For that, send us the shaft diameter, the type of fastening (keyway, set screw, etc.) and the quantity of units. We will confirm feasibility and quote via WhatsApp.
- How do I know if this sprocket is compatible with my chain?
- You must verify that your chain pitch is 3/4" and that the number of teeth (29) matches the transmission ratio you need. It is also important to check the shaft diameter and the fastening system. If you have doubts, send us a photo or the measurements of the original part and we will advise you.
