SKF sprockets of the PHS 25-1A series are toothed wheels for roller chains with a 25 pitch (8 mm), single strand. They are used to transmit motion between parallel shafts in industrial machines and equipment. MR Accesorios Industriales offers this line as part of its power transmission range, with advice to choose the number of teeth and hub type for each application.

The designation PHS 25-1A18 is read as follows: PHS identifies the SKF sprocket line; 25 is the chain pitch (8 mm); 1 indicates single strand; A defines the hub or mounting type; and 18 is the number of teeth. Examples in the series range from PHS 25-1A18 to PHS 25-1A25, that is, from 18 to 25 teeth. The more teeth, the lower the rotation speed for the same chain speed and the lower the load on each tooth.

These sprockets are used in chain drives of machine tools, conveyors, packing machines, bakery equipment and packaging lines. In Argentina they are found in the food, chemical and ceramic industries and in metalworking shops that assemble or replace transmission mechanisms. Being pitch 25, they are suitable for light loads and moderate speeds, typical of auxiliary shafts and feed mechanisms.

To select the sprocket, take into account the number of teeth according to the transmission ratio and available space. Check that the hub diameter and bore match the shaft. During installation, ensure alignment between sprocket and chain to avoid uneven wear; lubricate according to the operating conditions and check chain tension. If the equipment operates with a lot of dirt, evaluate guards or adequate lubrication.

SKF PHS 25-1A sprockets can be interchanged with other brands that use the same pitch and number of teeth, as long as the outside diameter, hub and bore match. It is not enough for the pitch to be the same: you must compare the hub type and fastening system. If in doubt, send the complete part number and shaft dimensions so that MR Accesorios Industriales can guide you on the equivalent.

If you need to replace a sprocket or assemble a complete drive, send the part number PHS 25-1A18 or the one shown on your equipment via WhatsApp. At MR Accesorios Industriales we will quote you and help you define the number of teeth and the mounting. You can also inquire about chains, pulleys and other power transmission components.
