R4 zz is small deep groove ball bearing

R4 zz is deep groove ball bearing, inner diameter :6.35mm, outer diameter :15.875mm, thickness :4.978mm.
Usually we refer to the r4 zz bearings refers to the inner diameter size within 10 mm single row micro deep groove ball bearings.
R4 zz bearings can be supplied in a variety of different materials, including bearing steel, stainless steel and ceramic.In addition to the conventional miniature bearings, we can also manufacture miniature flange bearings, miniature thrust bearings, or customized miniature non-standard bearings according to customer requirements.
Because the reasons for the heating of r4 zz bearings are different, the ways to solve them are also different. The following are the solutions when the temperature of miniature bearings is overheated:

1. Fat filling method, the so-called fat filling method is to regularly fill the working surface of the bearing with an appropriate amount of grease, which is one of the most commonly used fat lubrication methods.
2. the oil cup method, the oil cup method is set on the bearing seat screw cap type oil cup or pressure oil cup, regularly rotate the screw cap or oil gun to inject fat.This is also a common form of grease lubrication.
3. Pressure grease supply method, pressure grease supply method depends on grease pump grease supply.At this time should choose good liquidity grease.

4. the centralized grease supply method, the centralized grease supply method through the grease pump, at the same time to each r4 zz bearings and other parts of the grease supply.Similarly, at this time, the grease should be used for good flow, oxidation resistance and anti-corrosion grease, which is also a pressure grease supply method.
