Top Quality Two-way Load Bearings Alternating Axial Loads

Basic Information

Micro bearing refers to the metric series, the outer diameter is less than 9mm; Inch series, the outside diameter of all kinds of bearings less than 9.525mm! The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramic, etc., of which the minimum inner diameter can be 0.6mm, the general inner diameter is 1mm more

Product Feature

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.

Main Application

Micro bearings are suitable for all kinds of industrial equipment, small rotary motor and other fields with high speed and low noise, such as:

Office EQUIPMENT, MICRO MOTOR, INSTRUMENT, LASER ENGRAVING, SMALL WATCH, SOFT driver, PRESSURE rotor, dental drill, HARD disk motor, STEpper motor, VIDEO drum, toy model, computer cooling fan, money counting machine, fax machine and other related fields.

Matters Need 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 line is good, after the power with the test pen test.

4, press the start button, the host power.

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

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 iron sleeve, put the yoke iron on the top surface of the main machine, should be consistent with smooth.

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

Failure Cause

About 40% of the failure of ball micro bearings is caused by dust, dirt, debris pollution and corrosion. Pollution is usually caused by incorrect use and poor operating conditions. It also causes torque and noise problems. Micro bearing failures caused by the environment and pollution can be prevented, and the causes of such failures can be determined by simple visual observation. As long as the use and installation is reasonable, the denudation of micro bearings is easy to avoid. Denudation is characterized by indentation in the raceway of the miniature bearing ring caused by impact loads or incorrect installation. Denudation usually occurs when loads exceed the material yield limit. Denudation can also occur if the installation is incorrect so that a load crosses the miniature bearing ring. The pits on the miniature bearing rings also generate noise, vibration and additional torque

Solution

Because the reasons for the heating of micro bearings are different, the solutions are different. The following is the solution when the temperature of micro bearings is overheated:

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

2. Oil cup method, oil cup method is to set a screw cap type oil cup or pressure oil cup on the bearing seat, and rotate the screw cap or oil gun regularly to inject grease. This is also a common way of grease lubrication.

3, pressure grease supply method, pressure grease supply method is to rely on grease pump grease supply. At this time, grease with good fluidity should be selected.

4. Centralized grease supply method, centralized grease supply method through grease pump, at the same time to each deep groove ball bearing and other components. Similarly, at this time, the grease should be selected with good flow, oxidation resistance and corrosion resistance, which is also a pressure grease supply method.
