The double sprocket 3/8" Z20 is a toothed wheel sold by MR Accesorios Industriales, designed to transmit motion in 3/8" pitch chains. Its design with hub allows it to be mounted on shafts and coupled to other transmission components. It is used in equipment where two chains need to be driven in parallel or the motion shared between two lines. If you need a part for replacement or for a new development, this sprocket is supplied in SAE 1045 steel and is identified by its pitch and number of teeth.

This item is a double sprocket with hub, sold by MR in SAE 1045 steel. It has a 3/8" pitch and 20 teeth (z=20). The designation Double sprocket 3/8" Z20 summarizes these characteristics: the pitch indicates the chain that drives it and the number of teeth defines the transmission ratio. The hub is the central part that protrudes and allows mounting on the shaft, with space for the fastening system. Being double, it offers two toothed rows in a single part, which simplifies assembly and reduces components.

Typical applications of a double sprocket with 3/8" pitch and 20 teeth appear in low and medium power drives: agricultural machinery, conveyors, packaging equipment, lifting systems and drive mechanisms in general. It is also used in developments where the motion output needs to be duplicated or two chains working in parallel need to be synchronized. Due to its robust construction, it is common in environments with dust, vibration or moderate loads, provided that mounting and lubrication are adequate.

To correctly select this sprocket, take into account the chain pitch (3/8"), the number of teeth (20) and the diameter of the shaft on which it is mounted. The hub must have dimensions compatible with the shaft and the fastening system (key, set screw or taper bushing, as applicable). Also check the alignment between sprocket and chain, and leave the recommended tension to avoid premature wear. If the sprocket works in a gearbox or at high speeds, ask about balancing and available heat treatment.

If you need an equivalent or a nearby size, the most practical thing is to send us the full part number or the exact designation. We can evaluate variants in the number of teeth, the hub type or the material, as long as the 3/8" pitch is maintained. We also sell single sprockets and other toothed wheels for transmission. Tell us which chain you use and the shaft dimensions, and we will guide you toward the option that best suits your equipment.
