What's thin wall bearing characteristics and how to maintain?

Thin wall bearing products characteristics
In order to obtain bearing low friction torque, high rigidity and good rotary accuracy, a steel ball with small outside diameter was used.The use of hollow shafts ensures lightweight and wiring space.The thin wall bearing has realized the extremely thin bearing section, also has realized the product miniaturization, the lightweight.

The thin wall series 6700 and 6800 has all kinds of dustproof cover forms, with flange forms, stainless steel forms and wide forms, etc.

Maintenance procedure for thin wall bearing
1. Remove the wheel first. Remember to put the screw in place.

2. Take off the bearing. Some of the core of the wheel is so tight that it is difficult to remove the bearing.use the hexagon plate hand (is the one to remove the screw) to dig it down hard, rest assured, the bearing is not easy to break down!

3. Use the toothbrush to brush off the dirty surface of perine, you do not do this step, there is no difference!



4. Some bearings' side covers are detachable, while others are not.How to judge?Don't worry!If there is a C ring at the edge of the bearing side cover, it is detachable; if there is none, it is not detachable, but there are exceptions!

5. If it is detachable, it is very simple.Use the precision screwdriver of one word, in the notch of C ring, pry up C ring, and take the side cover off, as long as you remove one side!C ring and side cover to be put away, you "might" want to put them back after washing!

6. If it is undetachable, it will be more troublesome.You want to break it.Use the precision screwdriver to get into the seam of the side cover and prise it up with force. Don't doubt, that's it, but the side cover can't be put back!Well, throw it away!Remember, just take one side off and destroy both sides!

7. Remove the side cover of all bearings and start washing.Pour the stain oil into the bowl and toss the bearings.

Maintenance procedure for thin - walled bearings

First.Bearing installation and disassembly must be careful
Thin-walled deep groove ball bearings of different types and sizes are installed in different ways and tools, including mechanical or hydraulic.Here are some general basic installation methods and considerations.

1) do not install hard on the ball bearing, which will lead to partial overloading of ball bearing and contact surface and premature failure of bearing.

2) do not strike the surface of the bearing with a hard tool, such as a hammer or a screwdriver, which will cause the outer ring of the bearing to break or crack.

Second. Bearing cleaning
A clean working environment is very important for bearings.The roughness of the surface of the ring rotor and rolling element of thin-walled deep groove ball bearings is about 1/10 μm.The lubricant layer between the rolling surfaces is usually 0.2~1μm, and the particle type impurities larger than the lubricant particle size will be excessively crushed by the rolling element and generate local pressure in the steel of the central roller bearing, which will eventually lead to permanent material fatigue.In addition to this, dust particles in the external environment can be up to 10 μm, which can also cause damage to the aligning roller bearings.Because of this, clean and tidy working environment for the bearing is how important.

Third.Process testing of bearings
In the process of use, the operating temperature of the induction bearing can be adjusted through overheating. If the temperature is found to exceed the prescribed limit, the automatic alarm will be given to prevent the occurrence of the burning shaft.High temperature is often used to indicate that the bearing is in an abnormal condition.High temperatures are also harmful to the lubricant of the bearing.Sometimes thin - walled deep groove ball bearing overheating can be attributed to the bearing of lubricants.If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life.The causes of high temperature bearing include: insufficient lubrication of the bearing, unqualified lubricant, impurities in the bearing, excessive load, lack of clearance in the bearing, friction caused by oil seal, etc.
