Adapter sleeve

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 (fig. 1) or stepped shafts (fig. 2).

 (fig. 2)

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 standard assortment of adapter sleeves includes (product tables):

metric adapter sleeves

with a metric bore

with an inch bore

inch adapter sleeves

For larger sizes (bore diameter, d1 ≥ 1 060 mm) and variants not listed, contact SKF.

The sleeves are slit and are supplied complete with a lock nut and locking device:

Smaller sizes have a nut and a lock washer (fig. 1).

Larger sizes have a nut and a locking clip (fig. 2) or locking plate (fig. 3).

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.

Sleeves for oil injection

enable use of the oil injection method to mount and dismount bearings

are equipped with the necessary oil supply ducts and distribution grooves

as standard for metric sleeves with a bore diameter ≥ 200 mm (size ≥ 44)

on request for metric sleeves with a bore diameter ≥ 140 mm to < 200 mm

on request for inch sleeves with a bore diameter ≥ 4 5/16 inches (size ≥ 26)

include OH (metric) series, and OSNW and OSNP (inch) series (fig. 4, fig. 5, fig. 6 and fig. 7)
