MR supplies this double-row sprocket with hub, built for 3/8" pitch roller chains and cut with 11 teeth. Two chain strands can run on the same shaft thanks to its twin crowns, which suits drives that need to be duplicated or kept in step where space is tight. The part code to reference is MR-PINON-DOBLE-3-8-Z11.

Reading the designation is straightforward: 3/8" gives the chain pitch, Z11 gives the tooth count, and "double" tells you there are two rows of teeth on a single body with a hub. The hub is what lets you lock the sprocket onto a shaft with the right fasteners for your mounting. SAE 1045 steel is the material, a carbon grade that holds up under demanding mechanical service.

Typical installations include agricultural implements, conveyors, lifting gear and general power transmission. A double sprocket with hub earns its place when two parallel chains must run off one shaft, whether to duplicate a drive or to synchronize two strands. It also serves as a drop-in replacement for a worn sprocket where the mounting envelope is limited and a single part carrying two crowns is the practical answer.

Before ordering, confirm the chain pitch is 3/8", that 11 teeth gives the ratio you want, and that the shaft diameter and hub fastening match your equipment. Check the spacing between the two crowns against the chains you plan to run. Keeping the sprocket and chain aligned is what prevents premature wear. If any of these figures are unclear, send us the shaft and chain measurements.

Other tooth counts, different pitches or a single-row version are available if this one does not fit. Send the code MR-PINON-DOBLE-3-8-Z11 or the full designation by WhatsApp and we will quote it. The more detail you include — teeth, pitch, shaft diameter — the faster we can respond.

MR also supplies bearings, mounted units and housings, seals, lubrication and maintenance tools, plus power transmission components such as chains, sprockets, sheaves, belts and couplings. Split plummer block housings, roller chains and sheaves come from our own manufacturing.
