Bearing nylon cage, referred to as plastic protection, is a new generation of products that replace copper cages and iron cages. Compared with metal cages, it has numerous advantages:

First, it is light in weight, which makes the bearing more flexible. If it is used in electrical appliances or power consumption products, it has a great effect on energy saving.

Second, it has low noise and is the first choice for silent bearings. Especially, it has a great influence on electrical products with high noise requirements.

Third, it can effectively extend the service life of the bearing, and reduce the friction between the metal cage and the steel ball. For extending the life of the bearing, the role of plastic protection is great.
