Overview of the Miniature bearing
In ultra small aperture in the miniature bearing, miniature deep groove ball bearing type has the metric 68 series, 69 series, 60 series, etc. inch on a total of 6 R series, based on this, also can be divided into with ZZ steel dust cover bearing series, rubber sealing ring with RS miniature bearing series, teflon bearings seals series and flanged penal series and so on.There is also an introduction to angular contact ball bearings, welcome to browse.
Miniature bearings refer to the metric series, the outer diameter is less than 9mm; Inch series, all kinds of bearings with outer diameter less than 9.525mm! The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramics, etc., the minimum diameter can be 0.6mm, the general diameter is 1mm more.

Matters needing attention
1. Place the yoke iron on the end face of the main engine.
2. Insert the plug into the power socket with the control switch.
3. Check whether the grounding wire is good or not, and test with a test pen after power on.
4. Press the start button and the host will be powered on.
5, check the yoke iron should have no voltage to the ground.
6. Press the stop button to power off the host and stop heating.
7, according to different specifications of micro-bearings or other workpieces, choose different yoke iron sleeve, put the yoke iron on the top surface of the main engine, should be consistent and smooth.
8. When heating the miniature bearing, the sensor should be inserted into the "sensor socket", and the sensor should be attached to the heated workpiece.
The failure reason
About 40% of the failures of ball micro-bearings are caused by dust, dirt, debris pollution and corrosion. Pollution is usually caused by improper use and poor operating conditions. It also causes problems with torque and noise. The failure of miniature bearings caused by environment and pollution can be prevented, and the cause of such failure can be determined by simple visual observation. As long as the use and installation is reasonable, the erosion of miniature bearings is easy to avoid. Denudation is characterized by indentation on the raceway of the miniature bearing ring resulting from impact loads or improper installation. Denudation usually occurs when loads exceed a material's yield limit. Erosion can also occur if a load is mounted incorrectly across the miniature bearing ring. Noise, vibration and additional torque are also generated by the pits on the miniature bearing rings.
The solution
Because the reasons for the heating of miniature 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 deep groove ball 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.
The main purpose
Miniature bearing is suitable for all kinds of industrial equipment, small rotary motor of high speed low noise field, such as: office equipment, micro motor, instrument, laser engraving, small clock, soft drive, pressure rotor, dental drill, drive motor, stepping motor, VCR magnetic drum, toy models, computer cooling fan, paper, fax machine, and so on related areas.
