The SKF HE B adapter sleeve mounts a tapered-bore bearing on a cylindrical shaft. It comes as a set: a split sleeve, a lock nut, and a lock washer. Turning the nut expands the sleeve to create the fit. This lets you mount and dismount bearings without harming the shaft or the bearing, which is why it appears on so much industrial equipment.
The code tells you what you are holding. HE marks an adapter sleeve supplied with nut and washer. In the number that follows, the first two digits point to the bearing series, and the last two, multiplied by five, give the bore. The final B is a construction variant. Cross-check the part number against both the shaft size and the bearing before ordering.
You will find these sleeves in food processing, cement, mining, paper, and materials handling, wherever tapered-bore bearings are standard. Conveyors, mills, mixers, pumps, and fans are typical examples. MR Industrial Accessories supplies the SKF brand, and serves customers throughout the United States and in several Latin American countries.
Selection starts with the shaft diameter and the tapered-bore bearing you plan to mount. Keep surfaces clean and free of burrs during assembly. Tighten the nut with the correct wrench until you reach the internal clearance the bearing manufacturer recommends. The lock washer keeps the nut from backing off. Lubricating the sleeve eases assembly and guards against corrosion.
SKF HE B sleeves interchange with other brands that use the same standardized designation, such as FAG, NSK, or NTN. Even so, confirm dimensions and tolerances before substituting. What makes the swap work is the part number and the dimensions, not the brand name. If anything is unclear, send us the bearing part number and we will help you sort it out.
