Engineering plastics manufacturing bearing cages, and greater development in recent years, mainly because it has a certain degree of corrosion resistance, good self-lubricating properties, friction small, selects material conveniently and cheaper prices, manufacturing advantages such as easy, but easy to "aging". Reinforced nylon 66 that they currently use the most widely used, it can continue operating temperature range is-40~120sheshidu.
PTFE and high strength, good self-lubricating properties, continuous operating temperatures up to 300 degrees Celsius, phenolic adhesive tape has high mechanical strength, good abrasion resistance heat resistance, but costly, suitable for high speed spin around, working temperature is-40~150sheshidu, transient up to 180 degrees Celsius.
In bearing grinding process, its working surface is grinding through a high-speed rotating grinding wheel, grinding if you do not follow the operating instructions and adjust equipment, to appear on the bearing surface flaws, which affects overall quality of bearing.
