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

A sprocket designation reads as follows: PHS identifies the SKF sprocket line; the next block indicates the chain pitch according to standard; the following number indicates the number of strands; the letter corresponds to a hub or mounting configuration; and the final number is the number of teeth. In the series examples, such as PHS 05B-1A12 or PHS 05B-1A25, only the number of teeth changes. That number defines the drive ratio and the pitch line velocity: at the same pitch, more teeth mean a larger pitch diameter and lower rotational speed for the same chain speed.

Being made of steel, they withstand moderate loads and medium speeds, and they are combined with chains of the corresponding pitch to build simple speed reducers or increasers.

To select the sprocket, start from the chain you are going to use: the pitch must match the sprocket code. Then define the number of teeth based on the ratio and the available space. Check that the outside diameter does not interfere with other components and that the hub has the right bore for your shaft. During installation, take care of the alignment between sprocket and chain, the 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 standard and number of teeth. The key is to respect the pitch indicated in the code, the number of strands and the pitch diameter. If you need to replace an existing sprocket, compare the number of teeth and the hub type.
