For chain drives that need a direct shaft mount, this simplex sprocket with hub runs on 5/8" pitch chain and carries 31 teeth. MR supplies it in SAE 1045 steel as a replacement or build component for agricultural, industrial and transport equipment, and quotes it by part number through WhatsApp or email.

The part is a single-row sprocket machined from SAE 1045 steel, with the tooth pattern cut into a body that includes a central hub. That hub gives you a mounting surface on the shaft and a place to lock the sprocket with a set screw, a key, or both, depending on how the shaft is made. The 5/8" pitch tells you which roller chain it runs with; the 31 teeth set the ratio and the speed at the tooth circle.

Typical installations include conveyors, elevators, mills, mixers and material handling lines, as well as agricultural equipment such as seeders, harvesters and trailing implements where a defined ratio is needed. SAE 1045 steel handles moderate loads and contact wear, and the material can take a surface treatment when the application calls for more durability.

When you select a replacement, confirm three things: the chain pitch matches 5/8", the tooth count gives the ratio you want, and the hub fastening suits your shaft. Then check alignment between sprocket and chain, tension and lubrication. Poor alignment or a chain that is too tight will wear the teeth and the chain faster than normal.

If the exact part is not what you need, we can review an equivalent that keeps the same pitch and hub style. Send the part number, pitch, number of teeth, shaft diameter and a photo or sketch, and we will check options in our supply line or among the brands we carry.
