SKF PHF M series taper bushings are used to mount pulleys, gears, or bearings onto cylindrical shafts. The tapered design creates a tight fit and allows straightforward dismounting, which helps with maintenance and part replacement. They provide firm, precise clamping for power transmission setups.
The code PHF M-... breaks down as follows: PHF is the bushing series, M denotes the metric mounting type, and the number after the hyphen gives the nominal shaft diameter in inches as a fraction. For instance, PHF M-2 fits a 2-inch shaft, and PHF M-2-1/2 fits a 2 1/2-inch shaft. Fractional suffixes such as 1/8, 3/16, 1/4, 3/8, 5/8, or 3/4 indicate intermediate sizes in the series. This naming lets you identify the required size quickly.
These bushings appear in food, cement, mining, petrochemical, and general manufacturing operations. They are common in belt and chain drives where pulleys or sprockets must be fixed to shafts. You also find them in pumps, fans, conveyors, and mixers. Their capacity to transmit torque and handle radial and axial loads makes them suitable for demanding conditions.
Selecting the correct bushing starts with checking the shaft diameter and the hub dimensions of the mating part. To mount, insert the bushing into the hub and slide it onto the shaft; tightening the screws contracts the bushing for a firm clamp. Lubricate the thread and tapered seat before mounting to ease the fit and avoid damage. Shaft-to-hub alignment is critical for smooth operation and long assembly life.
For equivalences, SKF PHF M series bushings may work with other brands that follow similar standards, but always confirm exact dimensions and tolerances before replacing. Shaft diameter, bushing length, and thread type must match for safe mounting. Contact our technical team to verify compatibility with your application.

Frequently asked questions
- How do I determine the taper bushing size I need?
- Measure the shaft diameter where the bushing will be mounted. The code, such as PHF M-2, indicates the nominal diameter in inches. For an intermediate size like 2 1/2 inches, the code is PHF M-2-1/2. Also verify the hub dimensions.
- Are SKF PHF M bushings interchangeable with other brands?
- They may be compatible with bushings from other brands that follow similar specifications, but no universal equivalence exists. Compare exact dimensions, cone angle, and thread type. Consult us to confirm interchangeability for your case.
- What should I watch for when mounting a taper bushing?
- Clean and lubricate the thread and tapered seat before mounting. Ensure correct alignment between shaft and hub. Tighten screws evenly and progressively to the recommended torque. Avoid striking the bushing. Proper mounting ensures secure clamping and easier future dismounting.
