The EMMAR plain sprocket with hub, 1/2" pitch and 9 teeth, is a chain drive component made from SAE 1045 steel and supplied by MR. It transfers motion between parallel shafts in industrial equipment where a short ratio and straightforward shaft mounting are needed. The hub sits on the shaft and can be secured with a set screw or key, depending on how the shaft is machined. As a wear part, it should be inspected at regular intervals.

This sprocket carries a 1/2" pitch, which matches ANSI 40 chain, and 9 teeth (z=9). Tooth count sets the transmission ratio: fewer teeth mean higher speed at the driven shaft and less torque available. The hub is the central section that fits over the shaft, allowing fixation by set screw or key. MR supplies this item, and EMMAR manufactures it in SAE 1045 steel.

Typical applications include chain drives on agricultural machinery, conveyors, mixers, elevators and material handling systems. It also appears in factory equipment and machine tools that require a simple speed reduction or increase. Its compact size and hub make it suitable for small-diameter shafts and tight spaces where a larger wheel would not fit. Because it wears over time, check chain elongation and tooth condition periodically.

For correct selection, note the chain pitch (1/2"), the number of teeth (9) and the shaft diameter. Confirm that the hub bore and the fastening method (set screw or key) match your shaft. Careful alignment between sprocket and driven wheel helps prevent premature wear. At high speeds, verify balancing and lubrication. If you need guidance, contact MR.

If you require a different tooth count, pitch or size, send the part number or designation by WhatsApp. We can also quote an equivalent when you provide shaft dimensions, chain pitch and required teeth. We work with trusted suppliers and can evaluate options within the sprocket line. The more details you share, the more accurate our proposal will be.
