For mounting pulleys, gears, sprockets and similar components onto cylindrical shafts, SKF PHF TB taper bushings offer a self-centering taper design that simplifies alignment and provides a secure, removable connection. They are widely used in industrial and agricultural machinery.

The PHF TB code from SKF identifies a taper bushing. The numeric portion, like 1008 or 1108, denotes the bushing size: the first two digits correspond to the maximum bore diameter, while the last two relate to the outside diameter and length. An X separates the bushing code from the shaft diameter in inches, which may appear as a fraction, such as 0.5, 0.75 or 0.375. For example, PHF TB1008X0.5 is a 1008 bushing for a 1/2 inch shaft. Always confirm the actual shaft diameter before selecting.

These bushings are found in food processing, agriculture, mining and manufacturing, where torque must be transmitted between a shaft and a machine element. Typical equipment includes conveyors, mixers, pumps, fans and process machinery. Their self-centering feature and straightforward mounting suit applications that demand reliable fastening and the ability to disassemble without damaging the shaft.

Selecting a taper bushing involves the shaft diameter, the bore diameter of the mounted element and the torque to be transmitted. Installation requires inserting the bushing into the hub of the pulley or gear, aligning the holes and tightening the screws gradually and evenly. Clean the taper surfaces and apply the manufacturer's recommended tightening torque. The taper itself does not need lubrication, but adjacent bearings or bushings do. Proper alignment helps prevent vibration and premature wear.

SKF PHF TB taper bushings can be interchangeable with other brands that produce bushings of standardized dimensions, such as TB-type bushings. However, exact dimensions and the fastening system must be verified, as screws or tolerances may vary. Not all brands are identical, so comparing drawings or physical samples before replacing one bushing with another from a different source is advisable.
