Overview
NTN AS210D1 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.
Key features
- Mounts tapered-bore bearings on cylindrical shafts
- Reduces shaft machining cost
- Simplifies installation and removal
- Helps adjust bearing internal clearance
Typical applications
- Spherical roller bearing mounting
- Fans and conveyor pulleys
- Paper and steel equipment
- General industrial shafts
Selection guidance
Verify bearing bore taper, shaft diameter, sleeve series, locknut size, and residual clearance after mounting.
