Caster manufacturers talk about some knowledge about installing bearings

Among the components of the caster, the bearing is a very important part. Today, the caster manufacturer will talk about some knowledge about the installation of the caster bearing.

The installation instructions for various bearings are as follows:

1. Instructions for use of rolling bearings:
1. When installing the bearing, the force should be uniform, and it should not be directly hammered. For example, if the interference is large, the bearing should be heated in an air heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 120°.


2. Bearings equipped with nylon cages can work continuously and stably for a long time at -40°-120°, and should not work for more than 4 hours at 150°, and the short-term temperature peak can reach 180°.
3. The warehouse where the bearings are stored should be clean, dry and not allowed to be stored in the same warehouse with chemical products, the relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

2. Installation and use of deep groove ball bearings:
1. When installing the bearing, the force should be uniform, and it should not be directly hammered.

For example, if the interference is large, the bearing should be heated in an air heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 120°.
2. Bearings equipped with nylon cages can work continuously and stably for a long time at -40°-120°, and should not work for more than 4 hours at 150°, and the short-term temperature peak should not exceed 180°.
3. The warehouse where the bearings are stored should be clean, dry and not allowed to be stored in the same warehouse with chemical products, the relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.


4. Bearings in stock should be re-cleaned every other year and packed for rust prevention.

3. Installation and use of angular contact ball bearings:

1. When installing the bearing, the force should be uniform, and it should not be directly hammered. For example, if the interference is large, the bearing should be heated in an air heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 100°.


2. Bearings equipped with nylon cages can work continuously and stably for a long time at -40°-120°, and should not work for more than 4 hours at 150°, and the short-term temperature peak can reach 180°.
3. The warehouse where the bearings are stored should be clean, dry and not allowed to be stored in the same warehouse with chemical products, the relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

Fourth, the installation and use of spherical roller bearings:

1. The user should select the appropriate fit and bearing clearance according to the requirements of use. Please check the bearing code after unpacking.


2. Before the bearing is installed, if grease needs to be added to the bearing, the grease must be clean and appropriate.
3. When installing, it is advisable not to directly hammer the end face of the inner and outer rings and the rollers, so as not to crack the inner ring or the middle and small ribs. Usually, the user should put the bearing in mineral oil and install the spindle immediately when it is heated to 90°-100°.

Do not use the local spray burning method for the bearing, and the user should also install it with a special sleeve when it is difficult to "hot fit".
4. The bearing should have good sealing and dustproof device and lubrication during use, and the oil should not be cut off.
5. The bearing warehouse should be clean and dry, free from environmental pollution, the bearings should not fall to the ground, and the packaging should not be damaged.

Bearings that have been in stock for more than 1 year must be re-cleaned and oiled.

5. Installation and use of thrust spherical roller bearings:

1. When installing the bearing, clean the bearing oil seal, and then apply clean high-quality lubricating oil.
2. When installing the bearing, the force should be uniform and not hammered.

If the interference is large, the bearing should be heated to 90°-100° in mineral oil, and then installed immediately.
3. The warehouse where the bearings are stored should be clean, clean, and the relative humidity should not exceed 65%.
4. The bearings in stock should be cleaned and oiled every other year, and the oil seal packaging should be kept in good condition.


5. When using bearings, there should be good sealing and dustproof devices, and the working conditions should be checked frequently.

6. Installation and use of cylindrical roller bearings:

1. The bearing is a separate type, and the user can adjust the clearance according to their needs when installing.
2. Before the bearing is used, it should be cleaned with gasoline or kerosene and kept well lubricated.


3. When the bearing is installed, the bearing should be pressed into the component, and knocking is strictly prohibited.
4. The bearing storage place should be clean and ventilated to avoid moisture. Bearings that need to be stored for a long time should be regularly rusted.

Seven, thrust ball bearing installation and use:

1. When installing the bearing, the bearing seal should be removed, washed and then coated with clean high-quality lubricating oil.


2. When installing the bearing, the force should be uniform and not hammered. If the interference is large, the bearing should be heated to 90°-100° in mineral oil, and then installed immediately.
3. The warehouse where the bearings are stored should be clean, clean, and the relative humidity should not exceed 65%.


4. The bearings in stock should be cleaned and oiled every other year, and the oil seal packaging should be kept in good condition.
5. When using bearings, there should be good sealing and dustproof devices, and the working conditions should be checked frequently.
