Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain shafts or stepped shafts.
They are easy to install and require no additional location on the shaft. When used on plain shafts, the bearing can be located at any position on the shaft.
When used on stepped shafts together with an L-shaped spacer ring, the bearing can be accurately positioned axially, thereby facilitating bearing mounting and dismounting.
The SKF standard assortment of adapter sleeves includes (product tables):
- metric adapter sleeves
- with a metric bore
- with an inch bore
- inch adapter sleeves
The sleeves are slit and are supplied complete with a lock nut and locking device:
- Smaller sizes have a nut and a lock washer.
- Larger sizes have a nut and a locking clip (fig. 2) or locking plate.
Metric sleeves:
- with a bore diameter ≤ 180 mm (size ≤ 40) are phosphated
- with a bore diameter > 180 mm are coated with a solventless rust inhibitor
Inch sleeves are coated with a solventless rust inhibitor.
