This simplex sprocket with hub is designed for 3/4" pitch chains and comes with 34 teeth. The toothing and hub are machined as one piece from SAE 1045 steel, giving a rigid unit that mounts directly on a shaft with a keyway and set screw. It is a practical choice for chain drives where a fixed transmission ratio and straightforward installation are required.

The sprocket is identified by part number MR-PINON-SIMPLE-3-4-Z34. Key specifications include a 3/4" pitch, 34 teeth, and SAE 1045 steel construction. The simplex with hub design means the teeth and hub are integrated, which simplifies alignment with the driven sprocket and allows anchoring via a key and set screw. The machining and material treatment are already defined so that pitch and tooth thickness remain consistent.

Typical uses for this sprocket are in moderate-speed chain drives such as belt and roller conveyors, bucket elevators, food machinery, packaging equipment, and agricultural drive systems. It also serves as a replacement in gear reducers and transmission boxes where a 3/4" pitch is already established. Before installing, confirm that the chain matches the pitch and that the 34 teeth suit the required transmission ratio.

When selecting and mounting, check the shaft diameter and hub length against the available housing. Ensure parallel and angular alignment between this sprocket and the driven sprocket; misalignment increases wear on both chain and teeth. Lubrication with oil or grease reduces noise and friction. For variable loads, review the service factor and chain tension before startup.

To request a quote, send the part number MR-PINON-SIMPLE-3-4-Z34 or specify the pitch and number of teeth via WhatsApp or email. If you need a different hub diameter or an alternative tooth count within the same 3/4" pitch, the team can suggest options. Including a photo of the assembly or shaft data helps confirm the correct replacement.
