The simplex sprocket with hub, 1/2" pitch and 45 teeth is a chain drive sprocket sold by MR in SAE 1045 steel. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a specific transmission ratio and a 1/2" pitch chain are required. Its hub allows it to be mounted on a keyed shaft and secured with a set screw or bolt, depending on the assembly design.

This sprocket has a 1/2" pitch, 45 teeth (z) and is made of SAE 1045 steel. It is a simplex with hub type, which means it has a central machined hub for shaft mounting. Its commercial designation is Simplex sprocket 1/2" Z45 and its internal code is MR-PINON-SIMPLE-1-2-Z45. The hub provides a bearing surface and allows anchoring to the shaft by means of a key and screw, which is common in 1/2" pitch chain drives.

It is used in chain drives for agricultural machinery, conveyors, elevators, mills, mixers and power transmission equipment in general. It also appears in machine tools, packaging lines and motion systems where a transmission ratio determined by the number of teeth is required. Since it is sold by MR, you can ask about variants within the same 1/2" pitch series.

To correctly select this sprocket, take into account the chain pitch (1/2"), the number of teeth (45) and the diameter of the shaft on which it is mounted. The hub must match the shaft diameter and the keyway must be compatible. Also check the alignment between sprocket and wheel, the lubrication and the chain tension. If you need a different number of teeth or a different hub diameter, you can request a nearby size or an equivalent.

To request an equivalent or a nearby size, send the code MR-PINON-SIMPLE-1-2-Z45 by WhatsApp to MR Accesorios Industriales. If you have the pitch, the number of teeth and the shaft diameter, even better: that way the variant is identified quickly. You can also ask about sprockets from the same series with a different number of teeth or about compatible sprockets. The quote is made with the code or with the full designation.
