Why can nylon cages break out of metal cages and occupy an exclusive place in the cage market？

Advantages of nylon cages

Rolling bearings have two structures with and without cages. Large bearings generally require large loads, and may be filled with rolling elements between the inner and outer raceways without cages.

But:

Most small and medium-sized rolling bearings are equipped with a cage, the main role of the cage is:

The cage is equidistant from the rolling body and distributed on the circumference of the raceway to prevent collision and friction between the rolling body;

Guide and drive the rolling element to roll on the correct raceway;

Cage space to store grease;

In separate type bearings, the rolling element and a ring are combined to prevent the rolling element from falling off.

Nylon bearing cage vibration is small, low noise, low heat, high bearing capacity, can improve the limit speed and life of the bearing, usually can be in the -40℃+80℃ temperature range of long-term stable work, bearing lubricant compatibility, nylon bearing cage is suitable for motor, machine tools, gear shaft, pump, compressor and other fields.

Now nylon cages are being used more and more, so what are its advantages?

Bearing nylon cage, is the current replacement of copper cage, iron cage of a new generation of products, relative to metal cage, has a lot of advantages:

First, it is light weight, improve the flexibility of the bearing, if used in electrical appliances or power consumption products, for energy saving has a great role.

Second, it is light in weight, and the centrifugal force generated by the bearing in the rotation process is relatively small, which is more suitable for high-speed conditions.

Third, it has low noise and is the first choice for making silent bearings, especially for appliances with high noise requirements, nylon cages are the first to be selected.

Fourth, it has low friction and can effectively extend the service life of the bearing. The friction of the nylon cage on the rolling body is lower than that of the metal cage on the steel ball, which greatly extends the service life of the bearing.

Fifth, it is simple to manufacture, greatly improve production efficiency, reduce production costs.

Although the nylon cage has so many advantages, there are also many disadvantages in the use of bearings, mainly:

Nylon cage bearings can only work at room temperature.

The compressive strength of nylon cage is not as strong as that of metal plate cage, and the load capacity is not high.

Nylon cage bearings should not be used in an environment that is corrosive to them.

In short, the metal cage of the bearing and nylon cage each have advantages and disadvantages, in the selection should be selected according to the use of requirements, such as the use of low noise electrical appliances to choose nylon cage bearings, in high temperature, large load, large vibration of the equipment, it is preferred to choose stamped steel cage or machined copper bearings.
