Sprockets in the SKF PHS range with AH finish are made for roller chain drives. Mounted on a shaft, they engage the chain and carry motion and power through the machine. The line covers a broad set of pitches and tooth counts, so you can match a drive without changing the surrounding hardware. MR Industrial Accessories includes these sprockets in its power transmission line.

Reading the code helps you order the right part. PHS is the SKF sprocket family for roller chain. The number that follows is the chain pitch under the ANSI system. A -1 means a single strand. AH identifies the finish applied to the sprocket. The last digits give the tooth count. So PHS 40-1AH11 and PHS 50-1AH20 are single-strand sprockets for ANSI 40 and ANSI 50 chain, while PHS 60-1AH15 is built for ANSI 60 chain with 15 teeth.

These sprockets show up in food, beverage, packaging, textile, wood and ceramics plants, as well as in lifting and conveying equipment. Conveyors, mixers, agitators, pumps, compressors and general drive trains are typical homes for them. Their job is to move motion from a drive shaft to a driven shaft through the chain, keeping the two sides synchronized and absorbing the loads the drive produces.

When you select a PHS ...AH... sprocket, start with the chain pitch (40, 50, 60 and so on), then the tooth count that gives you the ratio you need, and finally the shaft diameter. Check that the bore and keyway fit the shaft. At assembly, line the sprockets up carefully; misalignment shows up as uneven wear and noise. Keeping the chain and sprocket lubricated also helps the assembly last. In corrosive or dusty areas, plan for extra protection.

On interchangeability, SKF PHS sprockets with AH finish follow the ANSI roller chain standards, so a sprocket from another maker that meets the same pitch, tooth count and shaft diameter can be used instead. Confirm the critical dimensions and the mounting type before you swap a part. MR Industrial Accessories can help you find the right replacement.
