The SKF taper bushing from the PHF TB line is a power transmission component used to fasten pulleys, gears and other elements to cylindrical shafts through an interference fit. Its double-cone design allows simple mounting and dismounting, without the need to machine the shaft. It is a reliable solution for transmitting torque in a wide variety of industrial applications.

The designation PHF TB…STX…IN is interpreted as follows: PHF identifies the category of SKF taper bushings; TB indicates that it is a bushing with flange and fastening screws; the numbers following TB correspond to the nominal size of the bushing, which defines its main dimensions; STX indicates the presence of a keyway, which allows additional torque to be transmitted; and IN specifies that the dimensions are in inches. For example, the code PHF TB3525STX4IN combines size 3525 with keyway and inch dimensions.

These bushings are used in industries such as food, mining, cement and metallurgy, where pulleys, gears, couplings and flywheels must be mounted on drive shafts. In Argentina, they are common in conveyors, mills, mixers and pumping equipment. Their ability to withstand axial and radial loads makes them suitable for applications with reversing rotation and high torques.

To select the correct bushing, take into account the shaft diameter, the torque to be transmitted and the type of load. Mounting is done by inserting the bushing into the hub of the element to be fastened and tightening the screws uniformly until reaching the recommended torque. It is essential to verify alignment between the shaft and hub, and to lubricate the threads and contact surfaces to facilitate future dismounting. The key, when present, must fit correctly in the shaft keyway.

Regarding equivalences, SKF taper bushings can be interchanged with those of other brands that follow the same dimensional standard, such as TB-type bushings or split bushings. However, always verify the tolerances and material before replacing a component, since small differences can affect performance. MR Accesorios Industriales carries the SKF brand as part of its power transmission line.
