High-precision bearings mainly refer to series B7000C (original code series 136000) and 760000 and accuracy grade P4, P5. Series B7000C bearings are mainly appalled for motor spindles, and its rotating and dimensional precisions are high, suitable for high-speed operation. Series 760000 bearings are mainly used for precise and high-speed tool machinery and precise measure equipments. Inner ring and outer ring are adopting refining bearing steel GCr15. Other steel materials are available on request. Balls are made of refining bearing steel, ceramic. Material of ceramic ball is Si3N4, ZrO2, and Al2O3. Ceramic ball is lower density, high wearing resistance, self-lubricating, particularly suitable for high speed, high precision and long life. Precision bearing's cages are mainly made of phenolic laminated resin or glass-fiber reinforced polyamide 66. Angular Contact Ball Bearings 7000 are used in forms of matched stack, and specific forms are referred to our company's web-specifications of matched angular contact ball bearing.
