It is used in agricultural machinery, conveyors, packaging lines and material handling equipment. MR sells it in Argentina through its distribution network.

This item is a simplex sprocket with hub of 1/2" pitch and 42 teeth, made of SAE 1045 steel. The designation Simplex sprocket 1/2" Z42 indicates that it has a single row of teeth and that its pitch diameter corresponds to 42 teeth. The hub is the central part that protrudes and allows mounting on the shaft, with space for a set screw or a key. It is a power transmission part used with 1/2" pitch chains. MR Accesorios Industriales sells it in the country, with dimensional control to ensure correct meshing.

Typical applications of this sprocket include agricultural machinery, chain conveyors, bucket elevators, packaging lines and material handling equipment. It is also found in low and medium speed drive systems where a specific transmission ratio is required. Being made of SAE 1045 steel, it withstands moderate loads and friction wear. It is common to see it on gearmotor output shafts or on intermediate shafts of machine tools.

To select and mount this sprocket, take into account the chain pitch (1/2"), the number of teeth (42) and the shaft diameter where it is mounted. The hub must match the shaft diameter and the fixing system must be suitable for the load. Verify alignment between sprocket and chain to avoid premature wear. Lubrication and chain tension are key to service life. If you need a different ratio, a sprocket with a different number of teeth can be evaluated.

If you are looking for an equivalent or a nearby size, the most practical thing is to send us the exact code of the sprocket you need to replace or the shaft and chain measurements.
