H318 Adaptor Sleeve 80mm
Sleeves permit bearings with a tapered bore to be tightly fitted on cylindrical shafts of broad
diameter tolerances. In general, the bore taper of such bearings is 1:12. However, spherical
roller bearings of the 240.. and 241.. series have a bore taper of 1:30.
Two principal types of sleeve exist:
H318 Adaptor Sleeve 80mm which generate a tight fit by driving the bearing along the sleeve.
Withdrawal sleeves, which generate a tight fit by driving the sleeve into the bore of the bearing.
The latter permit easy dismounting of the bearing by simple application of the appropriate
withdrawal nut.
The quality of bearing installation and fit is fundamental to the achievement of long and reliable
service. The cleanliness and suitability of the lubrication are also important factors.
