Description
SKF PHF J-80MM belongs to taper bushings and components, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PHF J-80MM and any equivalents.
Taper bushings from the SKF PHF J line lock pulleys, sprockets, gears and couplings onto plain cylindrical shafts. Because the grip comes from the tapered surfaces rather than a machined keyway or shoulder, the shaft itself needs no modification. MR Industrial Accessories supplies this line in bore sizes from 65 mm through 100 mm.
Reading the code is the fastest way to confirm what you need. PHF is the family name, J denotes the construction type, and the number that follows is the bore in millimeters. So PHF J-65MM fits a 65 mm shaft, PHF J-80MM an 80 mm shaft, and PHF J-100MM a 100 mm shaft. Match that number to your shaft diameter before ordering.
These bushings turn up wherever torque has to pass from a shaft to a hub and still be removable later: belt pulleys, chain sprockets and flexible couplings on conveyors, mills, pumps, fans, machine tools and process equipment. Food, chemical, petrochemical and metalworking plants are typical users.
Selection comes down to three things: shaft diameter, the torque the drive has to carry, and the conditions around the assembly. Before mounting, check that the cone and the hub bore are clean and free of burrs. A light film of lubricant on the threads and tapered surfaces eases assembly and helps prevent seizing. Draw the screws down evenly and in stages to the recommended torque, and keep shaft and hub aligned; good alignment cuts vibration and keeps the assembly running smoothly.
On interchangeability, bushings built to the same taper and dimensional standard can often be swapped between brands, but suffixes and tolerances are not always identical. Compare drawings and confirm the bore and taper rather than relying on the code alone.
Send the exact bushing code by WhatsApp or email and our team will confirm the size and mounting type, and suggest an equivalent when the original reference is not what you need.

Frequently asked questions
- What does PHF J-80MM tell me?
- It identifies an SKF PHF J series taper bushing for an 80 mm shaft: PHF for the family, J for the type, 80MM for the bore. Measure the shaft before mounting to be sure.
- How do I install a taper bushing?
- Clean the cone and hub bore, seat the bushing in the hub, then tighten the screws gradually in a cross pattern to the recommended torque. The taper produces the grip. Do not hammer it, and lubricate the threads.
- Can I replace it with another brand's bushing?
- Often yes, if the taper, dimensions and fastening method line up. Manufacturers vary, so compare drawings or send us the original code and we will check it.
