For drives that need to run two chains or two strands off a single shaft, this double sprocket with hub delivers. It runs on 3/4" pitch chain and carries 18 teeth, so the ratio depends on the mating sprocket. The body is machined from SAE 1045 steel, a grade that stands up to the wear and load cycles found in industrial service. MR supplies it as a replacement part and as a building block for new conveying or handling drives.

The part number MR-PINON-DOBLE-3-4-Z18 tells you most of what you need: double row, 3/4" pitch, 18 teeth. The hub is integral, so the sprocket mounts straight onto the shaft without a separate bushing. Two rows of teeth let you run two chains in parallel or pair two strands on the same shaft. MR checks dimensions before shipping so the teeth mesh correctly with standard 3/4" pitch chain.

Where do these sprockets show up? Chain conveyors, bucket elevators, material handling lines and general drive equipment. They also serve as drop-in replacements when a worn sprocket has changed the original ratio. If the hub bore or keyway needs adjustment, MR can review the machining to match your equipment.

Selecting the right sprocket starts with three checks: chain pitch must be 3/4", tooth count must match the ratio you need, and shaft diameter plus hub fastening must fit. During installation, keep the sprocket perpendicular to the shaft and set chain tension correctly. Misalignment or slack tension wears teeth and chain prematurely. Where the application allows, add lubrication and schedule periodic inspections.

Need an equivalent? Send the part number MR-PINON-DOBLE-3-4-Z18 or the full designation. MR can also look at variants in tooth count, hub style or material as long as the 3/4" pitch stays the same. To evaluate an alternative, share the equipment data, the chain you use, and a photo or drawing of the original sprocket.
