The double sprocket 3/4" Z27 is a chain drive sprocket with two toothed rings and a central hub, supplied by MR in SAE 1045 steel. It is used to drive two chains in parallel from a single shaft, or to reverse the direction of rotation in a single assembly. Its 3/4" pitch and 27 teeth place it in the range of medium to heavy drives, typical of continuous movement and conveying equipment.

This item is a double sprocket with hub, 3/4" pitch and 27 teeth, machined in SAE 1045 steel. The designation Double sprocket 3/4" Z27 indicates that it is a part with two toothed rings integral to a central hub, designed to be mounted on a shaft and drive two chains of the same pitch. SAE 1045 steel is a medium-carbon material, suitable for hardening and tempering, which gives it a good balance between wear resistance and toughness for industrial service.

Typical applications of a double sprocket of this type appear in drives where two chain strands must be moved from a single power source: roller conveyors, bucket elevators, drag chains in packaging lines and continuous movement machines. It is also used in configurations where two chains need to rotate in opposite directions, or where space requires concentrating the drive at a single point on the shaft.

To mount and select a double sprocket, it is advisable to verify the chain pitch, the number of teeth, the shaft diameter and the fastening system. The 3/4" pitch must match that of the chain; the 27 teeth define the transmission ratio and the pitch diameter. The hub allows mounting with key, set screw or taper bushing depending on the case. Check the alignment of the two rings with the chains and the condition of the rollers before starting up.

If you need an equivalent or a nearby size, the most practical thing is to send the part number MR-PINON-DOBLE-3-4-Z27 or the full designation. With the pitch, the number of teeth and the shaft diameter we can locate the part in the series or propose an alternative from the same category. If the original sprocket has no legible identification, send us the shaft measurements, the chain pitch and the number of teeth counted.
