How to use miniature ball bearing correctly?

968 Published by May 14,2018

Miniature ball bearing
Among the miniature ball bearing with ultra-small apertures, the types of miniature deep groove ball bearings are metric series 68, 69, 60, etc., and the imperial series R are 6 in total. On this basis, it can be divided into ZZ steel plates for dust prevention. Cover bearing series, with RS rubber seal miniature bearing series, Teflon Miniature ball bearing sealing ring series and flange flange series and so on.

Basic Information of Miniature ball bearing
Miniature ball bearing is metric series, with an outer diameter of less than 9mm. British series, all types of bearings with an outer diameter of less than 9.525mm! The main materials are carbon steel, bearing steel, stainless steel, plastics, and ceramics, among which the smallest inner diameter can be 0.6mm, and the inner diameter is generally 1mm.

The main purpose
Miniature ball bearing is suitable for various types of industrial equipment, small rotary motors and other high speed and low noise areas, such as:
Office equipment, micro-motors, instrumentation, laser engraving, miniature clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, VCR drums, toy models, computer cooling fans, cash registers, fax machines And other related fields.

Reason for failure of Miniature ball bearing
About 40% of ball ball bearing failures are caused by dust, dirt, debris, and corrosion. Contamination is usually caused by incorrect use and poor use of the environment. It also causes problems with torque and noise. Miniature ball bearing failures caused by the environment and pollution are preventable, and the cause of such failures can be determined by simple visual inspection. As long as it is used and installed properly, erosion of miniature bearings is easily avoided. Erosion is characterized by the presence of indentations on the Miniature ball bearing ring raceways due to impact loading or incorrect installation. Erosion usually occurs when the load exceeds the yield limit of the material. If the installation is not correct so that a load across the miniature bearing ring will also produce erosion. The pits on the Miniature ball bearing rings also produce noise, vibration and additional torque.
Precautions of Miniature ball bearing
1. Place the yoke on the end face of the main machine.
2. Insert the plug into the power outlet with the control switch.
3, check the grounding line is good, after the power test with a pencil.
4, press the start button, the host power.
5, check the yoke should be no voltage to the ground.
6, press the stop button host power off, stop heating.
7. According to different specifications of the Miniature ball bearing or other workpieces, choose different yoke sleeves, put this yoke on the top surface of the host, should be consistent with formation.
8. When heating Miniature ball bearing, insert the sensor into the “sensing socket” and place the sensor against the heated workpiece.
Solution Edit of Miniature ball bearing
Because of the different heating causes of the Miniature ball bearing, the solution is different. Here are the solutions for the overheating of the Miniature ball bearing:
1. The fat filling method, the so-called fat filling method, is to fill the bearing working surface with an appropriate amount of grease on a regular basis. It is the most commonly used grease lubrication method.
2, the cup method, the oil cup method is set on the bearing seat screw cap type oil cup or pressure oil cup, regular rotation screw cap or use the oil gun to inject the fat. This is also a common grease lubrication method.
3, pressure feeding method, pressure lubrication method is to rely on grease pump grease. At this point, a good fluidity grease should be used.
4. Concentrate the method of supplying grease, concentrate the method of supplying grease through the grease pump, and supply grease to each Miniature ball bearing and other components at the same time. At the same time, grease should be used for good grease, oxidation resistance and anti-corrosion grease. It is also a kind of pressure grease method.
