50X Dental Stainless Ceramic Ball Bearings For repairing NSK Handpiece

Features:

1. 50 high-speed dental ceramic bearings suitable for NSK high-speed handpieces.

2. High-precision miniature bearings use 9Cr18 stainless steel inner and outer rings (stainless steel material).

3. Precision bearings achieve P4 grade (ABEC 7 grade) tolerance accuracy, using ultra-hard ceramic (Si3N4) ceramic ball material manufactured by ASK Japan. The ceramic cup is made of self-made steel with a steel content of 30%-40%, which can reduce centrifugal force and sliding load caused by increased dynamic loads.

4. Uses imported Torlon PAI (polyamide-imide resin) from the USA, and 80-120 mesh phenolic resin material.

5. High-speed miniature dental bearings have advantages such as high rotational speed (up to 350,000-450,000 rpm), low noise, low frictional torque, and long service life.
