Deep groove ball bearings are the most common Rolling bearings. Its structure is simple and easy to use. Used primarily for radial load, but when you increase the radial clearance of bearings, has a certain amount of angular contact ball bearings, can be subjected to combined radial and axial loads. When in high speed and inappropriate use of thrust ball bearings can also be subjected to purely axial loads. Compared with other types of bearing of the same size, the bearings low friction, high speed limit. But not shock resistant and should not be subjected to heavy loads
Firstly, the ceramic bearing has the feature of corrosion resistance, the ceramic rolling bearing suitable for operation under harsh conditions covered corrosive media.
Secondly, since the ceramic ball rolling has lower density than steel, so which is much lighter, so when you rotate the outer ring centrifugal effect can be reduced by 40%, thus greatly extended service life.
Thirdly, the expansion and contraction of the ceramic affected smaller than steel, and therefore the gap of the bearing is constant, the bearing allows the temperature changes more severe environment.
Fourthly, as the ceramic has higher modulus of elasticity than steel, when the force is not easy deformation, and therefore help to improve the operating speed and achieve high accuracy.
Seals type of the skate bearings
RS:contact seal on one side of the bearing
2RS:contact seals on both sides of the bearing
Z:shield on one side of the bearing
ZZ:shields on both sides of the bearing
OPEN :each side have no shield and seal
Applications of skate bearings:
Ceramic bearings with the features of high temperature, cold, wear resistance, corrosion resistance, magnetic insulation, oil-free self-lubricating, high-speed and other characteristics. Can be used in extremely harsh environments and special conditions, can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, pumps, medical equipment, research and national defense and military fields, is application of new materials, high-tech products.
