SKF Locking Sleeves H 312 55 x 80 x 12.5

Type H Locking Sleeves
Locking sleeves are used to secure bearings with a tapered bore onto a cylindrical seat. When using locking sleeves on a smooth shaft, the bearings can be mounted at any position along the shaft. In contrast, when using stepped shafts along with a support ring, precise axial positioning of the bearing is possible, which also simplifies the disassembly of the bearings.
The locking sleeves are supplied complete with a nut and a retaining plate.
