SKF sprockets from the PHS series are chain sprockets for roller chain drives according to ANSI standard. They are mounted on shafts and mesh with the chain to transmit motion and power in a wide variety of machines. Their designation combines the chain pitch, the number of strands and the number of teeth, which allows selecting the exact part for each drive ratio. MR Accesorios Industriales sells this line as part of its power transmission offering.

The designation of these sprockets follows a clear pattern: PHS indicates the series, followed by a number that represents the chain pitch in eighths of an inch (for example, 06 for 3/8" pitch and 10 for 5/8" pitch), then B indicates it is for single-strand chain, and TBH with the final number indicates the number of teeth. Thus, a PHS 06B-1TBH19 is a sprocket for ANSI 06B single-strand chain with 19 teeth, while a PHS 10B-1TBH30 corresponds to 10B pitch with 30 teeth. This nomenclature allows quick identification of the part.

These sprockets are used in chain drives of industrial, agricultural and transport machines. In Argentina, they are common in conveyor belts, bucket elevators, machine tools, and equipment for the food, textile and wood industries. They are also found in drive systems for pumps, compressors and fans. Their versatility makes them suitable for applications requiring a constant and reliable drive ratio.

To select the right sprocket, take into account the chain pitch, the number of teeth, the shaft diameter and the mounting type. Verify that the bore and keyway match the shaft. Lubrication is essential: use the recommended lubricant according to speed and load. Ensure correct alignment between sprocket and chain to avoid premature wear. Sealing does not apply to this type of component, but axial and radial play must be minimal.

As for equivalents, SKF sprockets from the PHS series are interchangeable with other manufacturers that follow the ANSI standard for roller chains. When replacing, compare the pitch, number of teeth, outside diameter and bore. Interchangeability between brands is possible as long as the standardized dimensions are respected.
