High quality materials – The miniature bearings are made of high quality zirconia ceramics. As an important mechanical basic component, ceramic bearing is suitable for working under the harsh conditions of corrosive media because of its excellent performance against high temperature, super strength and corrosion resistance.
Light weight, long use – Since the density of ceramic rolling balls is lower than that of steel, the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.
Fast speed and high precision – Since the modulus of elasticity of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is beneficial to increase the working speed and achieve higher precision.
The influence of temperature is small – the influence of thermal expansion and contraction of ceramics is smaller than that of steel. Therefore, when the clearance of the bearing is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.
Application – Bearing inner diameter 8mm, outer diameter 22mm, thickness 7mm. It is suitable for 8mm shaft/rod projects such as mechanical equipment, electrical appliances, toys, motors, doors and windows. Suitable fields include optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery, automobiles, electronic equipment, metallurgy, electric power, textiles, and pumps.
