Micro bearing can simply be called micro-bearings, small part I below be replaced by miniature bearings micro bearings .

Miniature bearings refers to metric, outer diameter of less than 9mm; Inch series, various types of bearings is less than 9.525mm outer diameter! mainly made of carbon steel, bearing steel, stainless steel, plastics, ceramics, and minimal internal diameter of which can be done 0.6mm, diameter of 1mm more.

Miniature bearings product features:

Ultra small aperture of miniature bearings, types include miniature deep groove ball bearings series 68, 69 series, 60 series, total 6 inch r series, on this basis, can be divided into steel dust cover with ZZ bearings micro, RS rubber sealing ring bearing series, the Teflon sealing washer and flange flange series, and so on.

The main use of miniature bearings:

Miniature bearings are suitable for all kinds of industrial equipment, small rotary motor high speed low noise field, such as:

Office equipment, micro motors, instrumentation, laser engraving, watches, soft drive pressure rotor, Dental drill, drive motors, stepper motors, video recorders, drum, toy models, computer cooling fan, counting machines, fax machines and so on related fields.

Miniature bearing failure:

About 40% in spherical micro bearing failure is the dust, dirt, debris and pollution caused by corrosion. Contamination is usually caused by incorrect use and adverse environments caused by it will cause the torque and noise issues. Miniature bearing failure arising from environmental and pollution can be prevented, but also through simple observation with the naked eye can determine the cause of this failure. As long as the use and installation of reasonable, erosion of miniature bearings are easy to avoid. Erosion features are left on the miniature bearing ring raceway by impact loading or incorrect installation of the indentation. Erosion is usually occurs when the load exceeds the yield limit. If it's not installed correctly so that a load across the miniature bearing ring may have eroded. Micro-indentation on the bearing rings will generate noise, vibration and additional torque.

Miniature bearings heat Note:

1. place the yoke iron on the end surface of the host.

2. plug into the power socket on the control switch.

3. check that the ground wire is good, use pencil test after power on.

4. press the Start button, the host power.

5. check the yoke iron should be no voltage to ground.

6. Press stop button to host power stops heating.

7. the miniature bearings or other artifacts according to different specifications, selecting a different yoke sleeve, this put the yoke iron on the top surface of the host, should fit flat.

8. When heating miniature bearings, the sensor should be inserted "sensing socket" and close to the heated sensor artifacts.

Miniature bearing temperature of solution:

Miniature bearings heat for different reasons, so the solutions in different ways, here is a miniature bearing temperature of solution:

1. filling grease method

So-called filling grease method is to fill in the appropriate amount of grease to the bearing surface on a regular basis, is one of the most commonly used way of lubricating grease.

2. the oil Cup

Oil Cup is set on the bearing-cap oil or oil pressure oil Cup, regularly rotate the CAP gun grease or oil injection. This is a common way of lubricating grease.

3. pressure grease method

For grease method relies on the grease pump for grease pressure. Liquid grease should be used at this time.

4. method of centralized grease

Centralized grease method grease pump, while the deep groove ball bearings and other parts for fat. Similarly, his flow of grease should be used at this time and good resistance to oxidation and corrosion resistance of grease and a pressure grease method.
