When two chain strands must run in parallel from a single shaft, a double sprocket with hub is the straightforward answer. This 3/8" pitch, 19-tooth version is supplied by MR and is made of SAE 1045 steel. The two toothed rings are integral to a central hub, so both chains are driven at the same speed without an extra driven shaft.

The part number MR-PINON-DOBLE-3-8-Z19 identifies a double sprocket with hub. The 3/8" pitch matches ASA 35 series chain, and the 19 teeth set the pitch diameter and the tangential speed of the drive. Because the two rings share one hub, the unit mounts directly on the shaft, typically with a keyway or screw fastening to transmit torque.

Typical installations include double-chain conveyors, packaging and bottling machinery, lifting systems, assembly lines and machine tools where two strands have to stay synchronized. The hub can be adapted with a keyway or modified to suit specific machining requirements when the standard configuration does not match the shaft.

To select the correct sprocket, confirm three things: the chain pitch (3/8"), the tooth count (19) and the shaft diameter at the mounting point. The hub bore must match the shaft, and a keyway is normally needed for torque transmission. Check alignment between the two chain strands and verify that lubrication reaches both rings. Other tooth counts and pitches can be obtained as custom parts.

If you are matching an existing drive, send the part number MR-PINON-DOBLE-3-8-Z19 or the full designation. From there, other tooth and pitch combinations can be confirmed, a compatible replacement can be offered, and the matching chain and fastening method can be recommended. The goal is a component that fits your machine the first time.
