For drives that run 5/8 inch pitch chain, this simplex sprocket with hub carries 38 teeth and installs directly on a keyed shaft, secured with a screw. No separate hub is needed. The 38-tooth count sets the ratio you get at the driven shaft, so it is a common pick when a machine calls for a defined speed relationship rather than a stock ratio.

The sprocket is machined from SAE 1045 steel, a grade chosen for its strength and machinability in power transmission work. Its commercial designation is Simplex sprocket 5/8" Z38, and the item code to reference in any inquiry is MR-PINON-SIMPLE-5-8-Z38. Simplex refers to the single row of teeth; the hub is the central body that stiffens the part and provides the bore for shaft mounting.

You will find this size in chain drives on conveyors, packaging lines, mixers, agricultural equipment and general movement systems inside industrial plants, as well as in lifting mechanisms. Anywhere a 5/8 inch pitch chain has to change speed between two shafts, the 38-tooth count is what determines the ratio. The hub design makes it practical to mount on shafts of larger diameter and to lock the sprocket firmly in place.

When selecting the part, confirm three things first: the chain pitch (5/8 inch), the tooth count (38) and the shaft diameter at the mounting point. The bore has to match the shaft, and if a keyway is present, check that the key seats properly. Alignment between the two sprockets matters as much as the part itself, and chain tension should follow the transmission manufacturer's guidance. Keeping the drive lubricated is what protects the life of the assembly.

If your application needs a different tooth count, another pitch or a different hub bore, we can source it. MR Industrial Accessories LLC also supplies split plummer block housings, ANSI chains and sheaves, along with bearings, seals and lubricants. To find an equivalent, send the code you are running now, the number of teeth and the chain pitch, and we will help you match it.
