The SKF PHF SK-…MM series covers taper bushings designed for metric shafts. These components create a conical interference fit that locks a hub onto a shaft and transmits torque, making them a practical choice for mounting pulleys, gears, couplings and similar drive elements. They also simplify disassembly and help avoid shaft damage during service. MR Industrial Accessories includes this line within its power transmission range.
Reading the code is straightforward: PHF denotes the SKF taper bushing family; SK means the bushing is split, with a slot that lets it deform elastically as the screws are tightened; and the MM suffix confirms the nominal shaft diameter is given in millimeters. So PHF SK-28MM fits a 28 mm shaft, PHF SK-30MM fits a 30 mm shaft, and so on. This naming system makes it easy to match the bushing to the shaft size you have.
Typical users include food processing, cement, mining, petrochemical, paper and material handling operations. Conveyors, mills, mixers, pumps and fans often rely on these bushings to keep the driven element firmly attached to the shaft. The split design helps in tight spaces and can cut downtime, and because a keyway is often unnecessary, shaft machining becomes simpler.
Selection starts with the shaft diameter and the hub dimensions of the part being mounted. During installation, clean the mating surfaces, seat the bushing in the hub, then tighten the fastening screws evenly and in stages. Follow the recommended tightening torque and check alignment to prevent eccentric loading. A light lubricant on the threads and conical surfaces supports a proper fit. When in doubt, refer to the manufacturer's technical data.
Interchangeability with other brands that follow the same dimensional standard is possible, but not automatic. Confirm the shaft diameter, outer diameter and width, and make sure tolerances and cone angle match. For replacements, compare the critical dimensions or ask a specialist. MR Industrial Accessories can help you verify compatibility.

Frequently asked questions
- What does the MM suffix in PHF SK-…MM indicate?
- It shows that the nominal shaft diameter is measured in millimeters. For instance, PHF SK-30MM is sized for a 30 mm shaft, unlike inch-based versions.
- Can SKF PHF SK taper bushings replace other brands?
- They may be interchangeable when the key dimensions align: shaft diameter, outer diameter, width and cone angle. Check tolerances and consult a specialist before substituting.
- How do I install an SKF PHF SK-…MM taper bushing?
- Clean the surfaces, insert the bushing into the hub, and tighten the screws evenly and progressively to the recommended torque. Verifying alignment helps prevent failures.
