Super Precision Bearings High precision bearings are utilized in applications where superior accuracy, reliability of operation, high running speeds, long life, rigidity and limiting of noise and vibration are critical. Super precision ball bearings are utilized on machine tools, such as turning centers, milling, grinders, machining centers and to support linear screw. Other super precision bearings applications include aircraft, medical equipment and robotics. For more linear motion bearing direct from linear bearing manufacturers, contact us. How Are Precision Bearings Made? Standard ezo precision ball bearings generally use stamped steel cages. Extra bl precision bearings, on the other hand, use cages made from stainless steel, bronze, or phenolic Cages made from these materials offer higher speeds and better loading capabilities. What Is A Precision Bearing Used For? With high running accuracy, high-speed performance and high system rigidity, SKF super-precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and marine vessels. The bearings also minimize noise, vibration and heat generation. As a super precision bearings srl, we provide masta precision housing, beemer bearings, ceramic precision balls, linear motion components, etc. For more information, please feel free to contact us!
Feature of Ceramic ball: 1, corrosion resistance, strong acid and alkali, seawater can also be used. 2, light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3. 3, high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3. 4, high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating. Silicon nitride ceramic ball is a kind of precision ceramic sintered at high temperature in non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance. It can be used in seawater for a long time, and has good properties of insulation. At 800 C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of bearing steel. Small weight and small centrifugal force in rotation can achieve high speed operation. It is also self-lubricating, it can be used in the environment without high pollution of lubricating medium. It is the preferred material for ceramic bearings and mixed ceramic ball bearings.

These bearings are therefore particularly well suited for machine tool spindles where the high precision ball bearings arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness. VXO super-precision single row cylindrical roller bearing have a higher speed capability than double row bearings while double row bearings are more suitable for heavier loads. Features of Precision Cylindrical Roller Bearings High speed capability High radial load carrying capacity High rigidity Low friction Low cross-sectional height For more information about linear motion control systems, please feel free to contact us!
Model No. : 6000-6014; 6200-6218; 6300-6316; 607-609; 625-629 Type: Open, ZZ, Z, RS, 2RS, RZ, 2RZ, N, NR, ZNR, RSNR, ZZNR, 2RSNR Material: The type of bearing component materials used will determine the life span, reliability and performance of the bearings. However, there are many factors affecting the performance of the bearings which include the selection of the load carrying capacity, the rolling contact conditions, and the cleanliness of the operating environment and the dimensional stability of the bearing components. Fuda bearing limited has adopted the high-quality carbon-chromium steel material (Gcr15) in our production of the bearing. Size: Fuda company produces the standard size bearing according to the international ISO Standard for deep groove ball bearings. (Size range: I.D.: 8-90mm; O.D.: 22-170mm; W.D.: 7-39mm) Quality: There is a very strict QC system (based on the ISO standard) in Fuda company.
