Features
Adapter sleeves are the most commonly used components for locating bearings with a tapered bore into a cylindrical shafts seating. They are easily to mount, and require no additional location on the shafts. LBR adapter sleeves are produced from high-quality steel, have a very precise form, and an excellent price/performance factors ratio. LBR adapter sleeves are made as complete product, with lock nut and locking washer.
LBR supplies metric adapter sleeves, series designations H. The dimensions are in accordance with ISO 2982-1:1995.
Adapter sleeves consist of three elements: the actual sleeve, toothed washer MB. (for large sleeves lock washer of MS-type) and lock nut of KM or HM-type. The adapter number denotes the complete assembly of adapter sleeve, locknut and lockwasher.
As the name implies, adapter sleeves adapt themselves to the shaft diameter, so that wider diameter tolerances can be permitted than for the seat of a bearing with a cylindrical bore. However, the form tolerances must be kept within narrow limits as the accuracy of form directly affects the running accuracy of the bearing.
