About TB Woods Type SK SK28MM Sure-Grip Bushing, 28 Mm
This TB Wood’s Type SK Sure-Grip quick disconnect bushing has a torque capacity of 7,000 inch-pounds and is used for mounting a quick disconnect pulley, sheave, or sprocket on a drive shaft. It is split through the flange and taper to provide strong clamping on the shaft. The bushing is keyed to the shaft to prevent the shaft from rotating in the bushing, and it is interchangeable with quick disconnect bushings from various manufacturers. A set screw over the keyway helps to keep the key in place on vertical shafts and with vibrating loads. This quick disconnect bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances, among others.Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others.TB Wood's manufactures bushings, pulleys, couplings, and electronic motor controls.
