The essence of miniature ball bearings is ball bearings, the main materials are carbon steel, bearing steel, stainless steel and plastic. It is widely used in the production of various industrial equipment, small rotary motors and other high-speed and low-noise production.

Among the ultra-small diameter miniature bearings, the types of miniature deep groove ball bearings include metric 68 series, 69 series, 60 series, etc., and there are 6 types of inch R series. On this basis, they can also be divided into ZZ steel plate dustproof Cover bearing series, miniature bearing series with RS rubber seal ring, Teflon bearing seal ring series and flange flange series, etc.

 Precautions for miniature ball bearings

1. Place the yoke on the end face of the host.

2. Insert the plug into the power socket with the control switch.

3. Check whether the grounding wire is in good condition, and test with an electric pen after power on.

4. Press the start button to power on the host.

5. Check that there should be no voltage between the yoke and the ground.

6. Press the stop button to power off the host and stop heating.

7. According to different specifications of miniature bearings or other workpieces, choose different yoke sleeves, and place this yoke on the top surface of the host, which should be flat and consistent.

8. When heating the miniature bearing, the sensor should be inserted into the "sensing socket", and the sensor should be close to the heated workpiece.

Because the causes of the miniature bearing heat are different, the solution is also different. The following is the solution when the temperature of the miniature bearing is overheated:

1. Grease filling method. The so-called grease filling method is to fill the working surface of the bearing with an appropriate amount of grease regularly, which is the most commonly used grease lubrication method.

2. The oil cup method. The oil cup method is to set a screw cap oil cup or a pressure oil cup on the bearing seat, rotate the cap regularly or use a grease gun to inject grease. This is also a commonly used grease lubrication method.

3. Pressure grease supply method. Pressure grease supply method relies on grease pump for grease supply. At this time, grease with good fluidity should be selected.

Centralized grease supply method. The centralized grease supply method supplies grease to various deep groove ball bearings and other parts at the same time through a grease pump. Similarly, at this time, the grease should be a grease with good fluidity, oxidation resistance and corrosion resistance, which is also a pressure grease method.
