The MR-PINON-DOBLE-3-4-Z45 is a hub-type double sprocket built from SAE 1045 steel. It carries a 3/4" pitch and 45 teeth (z=45), and it links parallel shafts through a 3/4" pitch chain. The hub gives the part a wider seating area on the shaft. Within the power transmission range that MR supplies, this sprocket serves as a replacement item for industrial and agricultural machinery.
Reading the code: the 3/4" portion sets the chain pitch series, Z45 states the tooth count, and the double designation describes the hub arrangement, which adds two mounting supports or reinforcements. Material is SAE 1045 steel. MR supplies the sprocket with dimensional checks on both the toothing and the hub so it runs true with 3/4" pitch chains.
Where it fits: chain drives on conveyors, bucket elevators, mixers, material handling systems, and agricultural equipment. It also suits low and medium speed transmission arrangements that call for a 45-tooth sprocket with a heavy hub. Machining variations can be requested to match specific equipment needs.
Selecting the right unit starts with confirming the chain pitch is 3/4" and that 45 teeth give the transmission ratio you need. Then check shaft diameter and how the hub will be secured. At installation, align the sprockets and set chain tension per the equipment maker's instructions. Lubrication and accurate alignment both help the toothing last.
For an equivalent, ask about other tooth counts in the 3/4" pitch or sprockets in a different pitch. Have the part number MR-PINON-DOBLE-3-4-Z45 or the full designation ready, plus shaft and space measurements. MR Industrial Accessories can review supplying a similar part or propose an alternative from the power transmission line.
