Sprockets

Sprockets mesh with roller chains to transmit motion and force between parallel shafts. They are used in conveyors, elevators, agricultural equipment, process machines and general drives. They are selected according to the chain pitch, number of teeth (Z), number of strands and shaft mounting method: machined bore, with keyway or with taper bushing.

The key data is the pitch, the distance between roller centers, because it defines compatibility with the chain. In MR part numbers, the pitch and teeth are written: Single sprocket 1/2" Z8 is a single-strand sprocket for 1/2 inch pitch with 8 teeth. In SKF, PHS 05B-1A10 corresponds to ISO 05B chain, with 8 mm pitch and one strand. In Dodge, 35BTL18-1008 combines chain number 35, 18 teeth and the 1008 taper bushing with which it is mounted.

For selection, add the shaft diameter, strand type and free width on the shaft. Small teeth work with more impact and wear than large ones, so it is advisable not to go below a reasonable number of teeth on the drive sprocket, and always align sprocket and chain. With taper bushing, mounting and dismounting are quick and the same sprocket works for different shaft diameters.

We work with sprockets from SKF, Dodge and MR brand. To request a quote, send us the part number, or the chain pitch, number of teeth, number of strands and shaft diameter. If you have the part, a photo and the bore and outside diameter measurements are enough to identify it. Request a quote by part number at MR and we will respond promptly.
