do you know the maintenance and repair of metric thin section bearings?

The metric thin section bearings realizes a very thin bearing cross section, and also realizes miniaturization and weight reduction of the product. The diversity of products extends the range of uses. A metric thin section bearings has been realized, and the product has been reduced in size and weight. Product diversity expands its range of uses

metric thin section bearings maintenance

1. Remove the wheel first, remember to close the screw, and it will be troublesome if it is dropped.

2, remove the metric thin section bearings, some of the core of the wheel is very tight, the bearing is difficult to remove, use the hexagonal wrench (that is, the one to remove the screw) to force it to dig it down, rest assured that the bearing is not easy to break!

3, first use the toothbrush to brush off the dirty things on the surface of the Palin, you can not do this step, no bad!

4. Some of the side covers of the metric thin section bearings are detachable, while others are not. First, determine if you are detachable. How do you judge? Don't worry! If there is a C-shaped ring at the edge of the bearing side cover, it is detachable, no, it is not removable, but there are exceptions!

5, if it is detachable, it is very simple! Use a precision screwdriver with a word, in the gap of the C ring, pick up the C ring, then remove the side cover, just remove the side and it will be fine! C ring and side cover should be collected, wait for the wash you "may" want to put them back!

6, if it is not removable, it is more trouble! Use a destructive approach. Use a precision screwdriver to extend into the seam of the side cover, and force the side cover to pick it up. Don't doubt, that's it, but the side cover can't be loaded back! Well, throw it away! Remember, just remove the side and it will be ruined!

7. Remove all the side covers of the metric thin section bearings and start washing! Pour the oil into the bowl and throw the metric thin section bearings down and stir it.

metric thin section bearings repair steps

First, the metric thin section bearings installation and disassembly must be cautious

Different types and sizes of metric thin section bearings have different installation methods and tools, including mechanical or hydraulic. Here are mainly some general installation methods and precautions.

First, do not install hard on the ball, which will lead to partial overload of the ball and contact surface, leading to premature bearing failure.

Second, do not use hard tools, such as hammers, screwdrivers, etc., to hit the surface of the bearing, which will cause the outer ring of the bearing to break or crack.

Second, the cleaning of the metric thin section bearings

A clean environment is very important for metric thin section bearings. The surface roughness of the rotating surface of the thin-wall deep groove ball bearing ring and the rolling elements is about 1/10 μm, so that if the smooth ball surface is contaminated, the effect is very serious. The lubricating layer between the rolling surfaces is usually 0.2~1 μm. The particulate impurities larger than the lubricant particle size will be over-rolled by the rolling elements and cause partial pressure in the spherical roller bearing steel, which will eventually lead to permanent materials. fatigue. In addition to this, the size of the dust particles in the external environment can reach 10 μm, which can also cause damage to the spherical roller bearing. Because of this, how clean and tidy the working environment is for bearings.

Third, the metric thin section bearings process inspection

In the process of use, the operating temperature of the metric thin section bearings is sensed by heat drying. If the temperature exceeds the specified limit, it will automatically alarm to prevent the occurrence of the burning shaft. The use of high temperatures often indicates that the bearing is in an abnormal condition. High temperatures are also harmful to the lubricant of the bearing. Sometimes thin-wall deep groove ball bearings are overheated and can be attributed to the lubricant of the bearing. Long-term continuous rotation of the bearing at temperatures above 125 °C will reduce bearing life. The reasons for the high temperature bearing include: the metric thin section bearings may be insufficiently lubricated, the lubricant is unqualified, and the inside contains impurities. When the load is too large, the internal clearance of the bearing may be insufficient, and the oil seal may cause friction.
