27 engineering plastics (
Model steel)
Cage is an important part in railway freight car rolling bearings, and its security is the first requirement, engineering plastics not only need to have a certain strength, and also have higher requirements for toughness.
Engineering plastic cage than traditional metal cage has the following advantages: light weight, self-lubricating, low noise, low cost, high strength, impact resistance, abrasion resistance, especially in the condition of lack of oil security outstanding advantages, such as emergency.
