You don’t know the secret of thin-walled bearings

559 Published by Jul 11,2018

The thin section bearings realize an extremely thin bearing cross section, and also realizes miniaturization and weight reduction of the product. The diversity of products extends the range of applications. It is generally divided into plastic seal - RS, iron seal - ZZ, plane, iron card - K, copper card - M.

Product Features of thin section bearings
In order to obtain low friction torque, high rigidity and good rotation accuracy of the bearing, a steel ball with a small outer diameter is used. The use of a hollow shaft ensures space for wiring and wiring. The thin-walled bearing realizes an extremely thin bearing cross section, and also realizes miniaturization and weight reduction of the product. The diversity of products extends the range of applications.
The thin-walled 6700 and 6800 series are available in various dust cover forms, flanged versions, stainless steel forms, and wide format.

Maintenance steps of thin section bearings
1. Remove the wheel first, remember to close the screw, and it will be troublesome if it is dropped.
2, remove the bearing, 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 bearing side cover is detachable, and some can not, first determine whether you are Palin is 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, and then remove the side cover, just remove the side and it will be fine! C ring and side cover should be collected, wait for you to wash out "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 side cover and force the side cover to pick it up. Don't doubt, that's it, but the side cover won't go back! Well, throw it away! Remember, just remove the side and it will be ruined!
7. Remove all the side covers of the bearings and start washing! Pour the oil into the bowl and throw the bearing down and stir it.

Sealing means of thin section bearings
There are corresponding sealing devices installed on both ends of the bearing, but many people do not know what the sealing device does. Let's take a look at what the sealing device does for thin-walled bearings.
1. Keep the grease (oil) inside the bearing from being lost during use, and ensure that the bearing is in a lubrication state;
2. Protect the dust or harmful gases from the outside of the bearing from entering the bearing cavity to prevent damage to the bearing.
The sealing structure of the sealing ring is varied, so the sealing effect is also different. There is a gap between the sealing ring and the rotating shaft, which is called non-contact sealing. The smaller the clearance is, the better the sealing effect is, but the smaller the rotation speed of the shaft is allowed; the opposite is the opposite. There is no gap between the seal ring and the rotating shaft, which is called contact seal. The contact area of the contact lip of the seal ring is larger, the better the sealing effect is, but the smaller the rotation speed of the shaft is allowed, the opposite is the opposite. The main research content of the sealing technology is to research and develop the corresponding sealing device applied under different working conditions, and the compatibility of the sealing ring material with the corresponding grease.
