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 correct bushing, start with the shaft diameter, the diameter and taper of the bore of the component to be mounted, 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 installation and removal. The PHF J series is used to mount pulleys, gears and couplings on cylindrical shafts using screws, and is identified by a number that refers 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 that are not tapered and to replace press fits with a demountable system. In all cases, check shaft concentricity, surface condition and the tightening torque specified by the manufacturer to avoid loosening or deformation.

MR Accesorios Industriales supplies SKF taper bushings and components with 951 part numbers loaded in this subcategory, from Buenos Aires, Argentina. To request a quote, provide the complete bushing part number, the shaft diameter, the diameter and taper of the bore of the component to be mounted, 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 is used with a bearing, pulley or coupling, it is advisable to request a quote for the complete assembly to check taper and length compatibility. Contact us via WhatsApp or email with the part number and dimensions and we will send you the quote.
