To solve the potential problems of bearing skewing, difficult dismounting caused fretting corrosion and oil leakage, we have innovated a solution . The solution is patent right pending.

Key issue of the patent rights:Extending the width of the conventional slotted sleeves on its larger side, machine a thread at that position and fit a nut functional as a locating and withdrawal device . The device also valid for conventional adapter sleeve with oil duct and oil distribution grooves. The device is useful for avoiding bearing skew, more simpler driving up and easy to dismount the bearing.
