Description

6902 Ceramic Bearing Of Si3N4 races and balls + cage With P6/ABEC3 Precision

Description of 6902 Ceramic Bearing:

1. Si3N4 races and balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed after HIP (Hot Isostatic Pressure) sintering technology. So the porosity, wear resistance, crushing value and fatigue contact life have been greatly improved.

2. cage: has resistance to many kinds of acid and alkali and high temperature resistance.

Performance advantages of 6902 Ceramic Bearing:

Ceamic bearing 6902 in material of silicon nitride possesses light weight structure have good resistance to dry friction, low coefficient of linear expansion(3.3 10 -6/℃), self-lubrication, high fatigue life. They have high hardness (1580 HV5), high electrical and magnetic insulation and are wear-resistant, resistant to a variety of strong acid, strong alkali, salt corrosion (in addition to hydrofluoric acid, nitric acid). Its max work temperature can reach to about 1000 ℃, its service life is far beyond the same metal bearings several times to dozens of times, etc.

Application of 6902 Ceramic Bearing:

Silicon nitride bearings are suitable for high-speed, alternating load environment, so are usually use ashigh-speed spindle, electric spindle, CNC machine tool and motorized spindle bearings.
