The SKF PHS series sprockets are steel sprockets for chain drives, designed to be mounted on shafts and mesh with 05B pitch chains. They are used to transmit motion and force between parallel shafts in machines and industrial equipment. Their designation combines the pitch, number of strands and number of teeth, which allows selecting the exact part for each transmission ratio.

The designation PHS 05B-1A10 is read as follows: PHS identifies the SKF sprocket line; 05B indicates the chain pitch according to standard; 1 indicates single strand; A corresponds to a hub or mounting configuration; and 10 is the number of teeth. In series examples, such as PHS 05B-1A12 or PHS 05B-1A25, only the tooth count changes. That number defines the transmission ratio and linear speed: at the same pitch, more teeth mean a larger pitch diameter and lower rotation speed for the same chain speed.

These sprockets are used in chain drives of machine tools, conveyors, packaging equipment, mixers, pumps and drive systems in general. In Argentina they are common in the food, chemical and metallurgical industries and in process plants that need to synchronize shafts with a constant ratio. Being made of steel, they withstand moderate loads and medium speeds, and are combined with 05B pitch chains to build simple speed reducers or increasers.

To select the sprocket, start with the chain you will use: the pitch must match the 05B code. Then define the number of teeth based on the ratio and available space. Check that the outside diameter does not interfere with other components and that the hub has the correct bore for your shaft. During installation, take care of alignment between sprocket and chain, correct tension and lubrication: a misaligned or dry chain accelerates tooth wear.

SKF PHS series sprockets are interchangeable with other brands that follow the same pitch and tooth count standard. The key is to respect the 05B pitch, the number of strands and the pitch diameter. If you need to replace an existing sprocket, compare the tooth count and hub type. Do not invent equivalences based on manufacturer codes: be guided by standardized dimensions. MR Accesorios Industriales offers this brand as part of its power transmission line.

If you already have the sprocket code, chain pitch or tooth count, send it by WhatsApp to MR Accesorios Industriales. With that data we will quote the part you need and advise you on the compatible chain. We can also check interchangeability with the component you are replacing.
