A taper bushing from the SKF PHF SDS line locks a pulley, sprocket or similar hub onto a cylindrical shaft. The split-cone construction means the shaft stays as it is: no keyway, no machining. Mounting and removal are straightforward, which suits drives where the connection has to grip firmly but still come apart when the job calls for it.

Reading the code is the first step in selection. PHF SDS identifies the series, and the figure that follows gives the nominal shaft size in inches, so PHF SDS-1 fits a 1 inch shaft and PHF SDS-1-1/2 fits a 1 1/2 inch shaft. Fractional suffixes such as 1-1/8 or 1-3/16 cover the sizes in between. Each size also carries its own outside diameter range and tightening torque, both of which should be confirmed in the technical catalogue before ordering.

These bushings appear in conveyors, mixers, pumps, fans and machine tools, and in sectors ranging from food processing to chemical, mining and logistics operations. Because the clamping action takes up play, torque passes through without backlash, which matters on equipment that runs at higher precision. Doing away with keys also keeps hub and shaft design simpler and shortens maintenance work.

Before mounting, confirm three things: shaft diameter, required outside diameter and tightening torque. The bushing goes into the hub, then the fastening screws are drawn down evenly. Conical surfaces must be clean and free of grease. The cone itself needs no lubrication, though the screws benefit from an anti-seize compound. Keep shaft and hub properly aligned so the assembly does not see eccentric loads.

PHF SDS bushings can be exchanged with taper bushings built to comparable standards, including the 1008, 1108 and similar series, but the exact dimensions should always be checked rather than assumed. SKF is a brand known internationally for transmission components, and MR Industrial Accessories supplies this line within its range of industrial products. If the choice is not obvious, the technical team can point you to the right size.
