The SKF PHF TBU taper bushing is a keyedless mounting device that secures pulleys, gears, couplings and similar parts onto cylindrical shafts. Its tapered outer surface creates a concentric, tight fit that simplifies installation and removal while protecting both the shaft and the mounted component. It is a practical choice for power transmission in industrial equipment.
The code PHF TBU…MM tells you what you are holding. PHF is the SKF taper bushing family; TBU means a flanged, tapered bushing; the four-digit number that follows—2517, 3535 and so on—is the bushing size; and the MM suffix confirms a metric bore. For instance, PHF TBU2517X14MM fits a 14 mm shaft, and PHF TBU3535X90MM fits a 90 mm shaft. Reading the code this way lets you match the bushing to the job without guesswork.
You will find these bushings wherever torque must move from a shaft to a driven part: belt-drive pulleys, gearbox gears, flexible couplings, fans, pumps, conveyors and other process machinery. They hold up in food processing, chemical plants, mining, cement operations and water treatment facilities. Because they transmit torque without slipping and come apart easily, they suit equipment that sees frequent maintenance or changes in setup.
To choose the right bushing, start with two measurements: the shaft diameter and the hub bore of the part you are mounting. The bushing must match both the shaft and the tapered bore in the hub. When installing, wipe the tapered surfaces clean and free of oil, seat the bushing in the hub, slide the assembly onto the shaft, then tighten the screws in small, even steps until you reach the specified torque. Proper alignment matters—it prevents vibration and early wear.
Other brands that follow the same dimensional standard—TB-type bushings and similar—can often substitute for SKF PHF TBU bushings. Even so, check tolerances and the fastening method before swapping one brand for another. Interchangeability comes from the standard dimensions, not from the manufacturer’s code. If you are unsure about compatibility, ask us and we will help you compare.

Frequently asked questions
- How do I determine the taper bushing size I need?
- Measure the shaft diameter and the tapered bore of the hub where the bushing will sit. The part number encodes both: for example, PHF TBU2517X14MM indicates a bushing for a 14 mm shaft. If you prefer, send us your measurements and we will help you select the correct size.
- Can SKF PHF TBU bushings be replaced with other brands?
- Often yes, provided the standardized dimensions match. Taper bushings follow international standards that allow interchangeability across manufacturers. Always verify shaft diameter and hub dimensions before installing a different brand.
- What tightening torque should I use on the bushing screws?
- The correct torque depends on the bushing size and is normally given by the manufacturer. As a rule, tighten the screws evenly and progressively in a cross pattern until the bushing is secure. If you do not have the figure, contact us and we will provide it.
