Cores bearing factory
Deepgroove ball bearing are particularly versatile.They are simple in design,non-separable,suitable for high and even very high speeds and are robust in operation,requirying little maintenance.Deep raceway grooves and the close conformity between the raceway grooves and the ball enable deep groove ball bearings to accommodate axial loads in both directions,in addition to radial loads,even at high speeds,Single row deep groove ball bearings are the most widely used bearing type.
1.Low density. As the rolling body density decreases, high-speed operation of its centrifugal load is also reduced, which can work at higher speed.
2.Moderate elastic modulus. Elastic modulus is too large due to stress concentration and reduce the bearing capacity of the bushing.
3.Thermal expansion coefficient is small. Reduce the sensitivity to temperature changes, so that the bearing operating temperat.
4.High compressive strength. High compressive strength is the need for high stress for rolling bearings.
5.High hardness and high toughness. These two properties combine to achieve better surface roughness; and can prevent external par
6.Good anti-rolling contact fatigue and has a peel failure mode.
Special occasions should have high temperature, corrosion resistance and stability.
The ceramic material has low density, medium elastic modulus, thermal expansion coefficient is small, high hardness, high temperature, corrosion resistance, non-magnetic, etc., to silicon nitride ceramic ball for the rolling body of ceramic ball bearings can significantly improve the bearing contact fatigue life, Has greatly expanded the application of rolling bearings, has been widely used in a variety of high-precision, high-speed machine tools, automobiles, racing, subway, motor, aero engine, petrochemical machinery, metallurgical machinery and other fields.
