The SKF PHF TB taper bushing is a power transmission part that locks pulleys, gears, and similar components onto cylindrical shafts using an interference fit. Its double-cone construction lets you mount and remove the bushing without machining the shaft. This makes it a practical choice for torque transmission in many industrial settings.
The code PHF TB…STX…IN tells you what you are looking at. PHF is the SKF taper bushing family. TB means the bushing has a flange and fastening screws. The digits after TB give the nominal size, which sets the main dimensions. STX shows a keyway is present, so the connection can carry extra torque. IN confirms inch dimensions. For instance, PHF TB3525STX4IN is size 3525 with a keyway and inch measurements.
These bushings appear in food processing, mining, cement, and metallurgy operations, where pulleys, gears, couplings, and flywheels need to sit on drive shafts. They handle axial and radial loads, so they work in reversing rotation and high-torque drives. Typical equipment includes conveyors, mills, mixers, and pumps.
Choosing the right bushing starts with the shaft diameter, the torque to transmit, and the load type. To install, slide the bushing into the hub of the component, then tighten the screws evenly to the recommended torque. Check that shaft and hub are aligned. Lubricate threads and contact surfaces so removal later is easier. If a key is used, it must seat properly in the shaft keyway.
For replacements, SKF taper bushings can interchange with other brands that share the same dimensional standard, such as TB-type or split bushings. Still, confirm tolerances and material before swapping a part, because small differences can change how it performs. MR Industrial Accessories supplies the SKF brand within its power transmission range.

Frequently asked questions
- How do I install an SKF PHF TB taper bushing?
- Place the bushing in the hub of the component, align it with the shaft, and tighten the screws gradually and evenly to the specified torque. Lubricate the threads and check alignment for correct mounting.
- What does STX mean in the designation?
- STX indicates the bushing has a keyway. This allows higher torque transmission by preventing slippage between shaft and bushing, and it is common in high-load applications.
- Can SKF bushings be replaced with other brands?
- Yes, SKF taper bushings follow dimensional standards that permit interchange with other brands when tolerances and material are respected. Verify specifications before replacing a component.
