  • How to Produce Bearing Balls?
    • Jul , 08 2020

    1.Heading: In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies. Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates. 2.Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision. 3.Heat-treating: Carbon steel balls are next carburized an...

  • What is a Hybrid Ceramic Bearing?
    • Aug , 19 2020

    Hybrid Bearing are consist with inner and outer ring material bearing steel &stainless steel ,and inner ball with ceramic ZR02 or Si3N4  and we are alway produce with PA66 retainer . Seal type:2RS,ZZ or Open Features: (1) The temperature resistance is high, the thermal expansion coefficient of the ceramic ball is small, and the bearing ball will not expand due to temperature in a high tem...

  • Ceramic Silicon Nitride (Si3N4) Introduction
    • Aug , 27 2020

    Silicon nitride is very strong, especially hot-pressed silicon nitride, which is one of the hardest materials in the world. It has high strength, low density, high temperature resistance and other properties. It is extremely resistant to high temperatures, and its strength can be maintained to a high temperature of 1200°C without falling. It will not melt into a melt after being heated, and will n...

  • Advantages of plastic ball bearings compared to metal bearing
    • Sep , 03 2020

    The Features Of Small Plastic Ball Bearing : 1. The whole plastic bearing is lubricating material with long service life; while the lubricating layer of metal sliding bearing is only 0.003mm PTFE on the surface, when this thin layer of friction is finished, it will declare the end of service life; 2. The use of plastic bearings will not rust and is corrosion resistant, and metal bearings are easy ...

  • 608 Bearings 6 Balls VS Balls
    • Sep , 15 2020

    ZZ BEARING can produce 6 balls with diameter 3/16 inch balls and the 7 balls diameter is  5/32 inch. The Features of 6 Balls Bearings : 1.6 bigger balls diameter aer larger than 7 balls ,so they are stronger and hte speed can be faster. 2.with larger balls ,608 bearings can with less friction at the same wheel RPM 3.With 6 balls ,bearing can roll farther with the reduced friction and ball ro...
