  • Why Bearings Will Rust?
    • May , 11 2020

    The main causes of bearing corrosion: 1. Metal surface  (corrosion of batteries with poor oxygen concentration). 2. The chemical composition and structure of the metal material itself. 3. The composition and pH value of the solution in contact with the metal surface. 4. Ambient temperature and humidity. 5. Various environmental media in contact with the metal surface. 6. Human sweat is also t...

  • Which Material Is Used To Make Bearings?
    • May , 24 2020

    There are so many type of bearing material ,such as : Chrome Steel - SAE 52100 Stainless Steel Carbon Steel Plastic Ceramic (ZRO2,SI3N4) Sic ,for high temperature bearings The most common bearings material is Chrome steel Gcr15 ,this material can produce all type all bearings ,such as ball bearing ,roller bearings . And ball bearings inner ring ,outer ring ,ball ,cage are produce with chrome steel...

  • 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 ...
