SKF PHS sprockets are engineered for high-pitch roller chains, built from high-strength steel and heat-treated to handle demanding loads. They keep drives synchronized and durable in mills, elevators, and conveyors. MR Industrial Accessories supplies this line as part of its power transmission range and offers technical guidance to match pitch, tooth count, and bushing style to your application.

Decoding a PHS code is straightforward when you break it into segments. After PHS, the first number gives the chain pitch in eighths of an inch. The letter H signals the high-pitch chain type. Following the hyphen, a digit shows the number of strands—single, double, or triple. The final B plus a number identifies the taper bushing diameter. For instance, PHS 120H-3B17 means pitch 120, high-pitch type, three strands, and bushing B17. Understanding this structure helps you order the right replacement without guesswork.

These sprockets appear in food processing, cement, mining, and material handling operations. You will find them on bucket elevators, drag conveyors, flour mills, and bottling lines. Their sturdy design transmits power reliably in dusty, humid, or moderately hot environments, as long as the pitch and tooth count suit the speed and load of the system.

When selecting a sprocket, consider chain pitch, number of teeth, strand count, and bushing type. A taper bushing simplifies installation and removal without hammering. Check alignment between sprocket and chain, and maintain proper lubrication to minimize wear. For pulsating loads, choose a tooth count that spreads stress more evenly and reduces the risk of chain jumping.

SKF PHS sprockets can replace those from other manufacturers that follow the same pitch standard and bushing configuration, provided pitch, tooth count, and bushing diameter match. A similar code alone is not sufficient; critical dimensions must be compared. MR Industrial Accessories can help you verify interchangeability before you commit.
