The SKF taper bushing of the PHF F line is a fastening element that allows pulleys, hubs, gears and other components to be mounted on cylindrical shafts without machining keyways or press fits. It is installed between the shaft and the hub: when the screws are tightened, the taper contracts onto the shaft and expands against the hub, creating a firm and removable interference joint. It is a common solution in power transmission when precise centering and easy replacement are needed.

The PHF F-# designation reads as follows: PHF identifies the SKF taper bushing family, F the construction type and the final number the nominal shaft diameter in inches. That is why codes such as PHF F-1, PHF F-1-1/8, PHF F-1-1/4, PHF F-1-3/8, PHF F-1-1/2, PHF F-1-5/8 or PHF F-1-3/4 coexist: they all share the same mounting concept and differ only in shaft size. Suffixes with a fraction, such as PHF F-1-3/16, indicate intermediate diameters that are not always covered by the basic lines.

On the plant floor, these bushings appear in belt pulleys, conveyor belt hubs, fans, pumps, mixers and process equipment. They are also used in agricultural machinery, packaging lines and internal transport, where quick replacement of a component without disassembling the whole shaft is a concrete advantage. In Argentina they are frequently seen in maintenance of food, chemical and materials plants, because they allow the pulley or gear to be replaced without lathe work or additional fitting.

To select the bushing, start from the actual shaft diameter and the hub you are going to mount: the code must match both. Check the condition of the shaft surface, free of burrs or wear, and the cleanliness of the taper faces. Lubricating the threads and the taper helps the tightening be even; follow the screw sequence indicated by the manufacturer and check the torque with a torque wrench. Careful alignment between shaft and hub prevents vibration and extends the life of the assembly.

As for interchangeability, taper bushings of this type are chosen by shaft size and by the compatible hub, not by brand. Different manufacturers offer equivalent geometries, but it is advisable to confirm the diameter, length and number of screws before replacing one with another. If the hub or pulley is already prepared for a taper bushing, the most practical approach is to keep the same code and verify that the new bushing fits into the taper without play.

If you have the bushing code at hand, send it on WhatsApp to MR Accesorios Industriales along with the shaft diameter and a photo of the hub. With that data we confirm the equivalent option and quote you. MR carries SKF as an official brand within its power transmission line, so you can resolve your inquiry in a single contact.
