Taper bushings and components

Taper bushings are precision components mounted between a cylindrical shaft and the tapered bore of a bearing, pulley, gear or coupling. Their conical shape creates a controlled interference fit when the screws are tightened, achieving a firm, centered grip without machining the shaft or using keys. To select the right bushing, start with the shaft diameter, the bore diameter and taper of the element to be secured, and the torque the assembly will transmit.

The SKF PHF FX line consists of taper bushings for mounting bearings with a tapered bore on cylindrical shafts, with simple mounting and dismounting. The PHF J series is used to secure pulleys, gears and couplings on cylindrical shafts by means of screws, and is identified by a number referring to the shaft diameter. The PHF SF, PHF SK, PHF SD and PHF SH codes correspond to different constructions and diameter ranges within the same family. The PHF TB models are split taper bushings, and the PHF E, PHF F, PHF M, PHF JA and PHF P cover other geometries and fastening applications.

In practice they are found in gearboxes, pumps, fans, conveyors, machine tools and power transmission equipment in general. They are also used to mount bearings on shafts without taper and to replace press fits with a dismountable system. In all cases, it is advisable to check shaft concentricity, surface condition and the tightening torque specified by the manufacturer to prevent loosening or deformation.

MR Accesorios Industriales sells SKF taper bushings and components with 951 references in this subcategory, from Buenos Aires, Argentina. To request a quote, provide the complete bushing code, the shaft diameter, the bore diameter and taper of the element to be secured, and if you have the equivalent from another brand or the drawing number, even better: that allows us to identify the exact reference without back and forth.

If the bushing goes with a bearing, pulley or coupling, it is advisable to quote the complete assembly to check taper and length compatibility. Write to us via WhatsApp or email with the code and dimensions and we will send you the quote.
