The SKF PHF SF taper bushing is a fixing component mounted between the shaft and the hub of pulleys, gears, couplings or hubs. Its taper and keyway allow torque transmission with a firm, removable fit, without machining the shaft. It is used in power transmission and in equipment where a part needs to be centered and secured on the shaft in a repeatable way.

The PHF SF designation identifies the family of SKF taper bushings with keyway and mounting holes. The number following SF- is the nominal size of the bushing in inches: that is why PHF SF-1, PHF SF-1-1/8, PHF SF-1-1/4 or PHF SF-1-3/4 coexist. When an additional suffix appears, as in PHF SF-1-1/2, it is a variant within the same base size. Before ordering, check the complete code engraved on the bushing.

These bushings are found in food, cement, mining, aggregate processing plants and in transmission lines with pulleys and gears. They also appear in pumping, ventilation and bulk conveying equipment. In Argentina they are found in maintenance of mills, conveyor belts and process machines where the shaft is already defined and a standard taper fixing is sought, without additional turning.

To select the correct bushing, compare the shaft diameter with the nominal size of the code and check the taper of the hub. The keyway must match the shaft key. During assembly, clean the tapered surfaces, apply the screw torque in a cross and progressive pattern, and check the alignment between shaft and hub. Proper lubrication of the thread and the use of the correct wrench prevent deformation and loosening.

Taper bushings are interchangeable between brands by nominal size and taper, but it is not advisable to mix components of different origin without verifying the angle and position of the keyway. The SKF PHF SF reference is a known standard; if the equipment carries another code, it is advisable to compare critical dimensions before replacing. MR Accesorios Industriales sells SKF as an official brand within its power transmission line.

If you already have the bushing code, send it by WhatsApp to MR Accesorios Industriales along with the shaft size and a photo of the hub. With that data we confirm the equivalent variant and send you the quote. We can also advise you if the current bushing is marked or if you need to replace the complete assembly.
