SKF PHS series sprockets and chain wheels are power transmission parts that mount on a shaft and engage a roller chain to carry motion and torque through industrial machinery, from conveyors to process equipment. The series is built to handle the loads and speeds found in chain drives, and it forms part of the power transmission range we supply to maintenance and purchasing teams across the United States and Latin America.

Reading a PHS code is straightforward once you know the order of the blocks. Take PHS 10B-3C76: PHS is the chain sprocket family, 10B gives the chain type and pitch under ISO 606 (5/8" pitch), -3 tells you the number of strands, C is the hub type or configuration, and 76 is the tooth count. So PHS 12B-2C68 is a double-strand sprocket for 12B chain (3/4" pitch) with 68 teeth. Suffixes can change with the mounting, but the last figure is always the number of teeth.

You will find these sprockets in the chain drives of belt and roller conveyors, elevators, mixers, mills, food and beverage equipment, and packaging lines, as well as in metallurgical, cement, sugar and processing plants and in agricultural implements and harvesting machinery. The PHS range spans multiple pitches and tooth counts, which lets you set the transmission ratio and output speed to suit the drive.

Selection comes down to four items: chain pitch, number of strands, number of teeth and shaft diameter. Confirm that the hub and fastening method match the mounting you have. Alignment between sprocket and chain, plus correct lubrication, is what keeps wear and noise down. In dusty or damp environments, look at suitable lubricants or added protection. The sprocket should sit perpendicular to the shaft with no excessive axial play.

Because PHS sprockets follow international dimensional standards for roller chains, they can be interchanged with other brands that meet the same pitch, tooth count and shaft diameter. Before replacing a component, check the full code and the critical dimensions, and compare hub dimensions, outside diameter and bore, since interchangeability depends on how closely manufacturing standards and tolerances match.
