HIGH PRECISION ROLLERS
The main production of high precision roller, with high load, long life characteristics. Mainly used in heavy truck bearings, railway bearings and wind power bearings.
Keywords: special steel ball for precision motor | special steel ball for automobile | special steel ball for wind power
Description
Specifications
Low density and wear resistance of silicon nitride ceramic ball, low wear rate, can still maintain excellent wear resistance in high speed, high temperature, high pressure and other harsh environments;
The corrosion resistance and insulation of silicon nitride ceramic balls, reducing galvanic corrosion due to motor discharge;
Excellent high temperature resistance of silicon nitride ceramic ball, can work stably for a long time under 1200°C, and the instantaneous high temperature resistance can reach 1500°C;
The coefficient of thermal expansion of silicon nitride ceramic ball, about 3x10^-6/°C, has a small size change in the occasion of large temperature changes. In the high temperature environment will not be caused by the temperature of the bearing ball expansion, the temperature of the ordinary bearing in about 160 degrees, ceramic ball bearing can reach more than 220 degrees;
The surface roughness of G5 grade silicon nitride ceramic ball is below 0.014um, higher finish, small friction coefficient, reduce bearing wear;
Silicon nitride ceramic ball can not add any grease, even if the grease is dried out, the bearing can operate normally, so as to avoid the occurrence of premature damage to the bearing caused by grease drying out in ordinary bearings. The service life of the bearings with ceramic balls is 2-3 times that of ordinary bearings.
