Overview

NTN H3026 Adapter Sleeve is a mounting accessory used to secure tapered-bore bearings on cylindrical shafts. It simplifies installation and removal of spherical roller and self-aligning ball bearings, reducing shaft machining complexity and maintenance time.

It consists of a tapered sleeve, locknut, and lock washer or locking device. Tightening the nut drives the bearing inner ring onto the taper and clamps it to the shaft.
