Six types of bearings common types of installation matters

Current Position: Home > MATERIAL
Bearings are relatively unfamiliar to most of us, but we are often exposed in daily life, but we don’t know much about them. For example, tire bearings on children’s toy cars, refrigerators, and air-conditioners have bearings. The main types of bearings we use are: deep groove ball bearings, angular contact ball bearings, spherical roller bearings, thrust spherical roller bearings, cylindrical roller bearings and thrust spherical roller bearings. For the correct installation of the bearing, China Bearing Network shares the following installation items based on experience.

First, deep groove ball bearing installation matters



Deep groove ball bearing

1. When installing the bearing, it should be evenly stressed and cannot be hammered directly. For example, if the interference is large, the bearing should be placed in an air-heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 120°.

2. Bearings with nylon cages can operate continuously for a long period of time at -40°-120°, should not exceed 4 hours at 150°, and 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 as the chemical products. The relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

4. The stock bearing should be cleaned again every other year for rust-proof packaging.

Second, angular contact ball bearing installation matters



Angular contact ball bearings

1. When installing the bearing, it should be evenly stressed and cannot be hammered directly. For example, if the interference is large, the bearing should be placed in an air-heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 100°.

2. The bearing with nylon cage can work continuously for a long time at -40°-120°. It should not exceed 4 hours at 150° and the peak temperature 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 as the chemical products. The relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

Third, spherical roller bearing installation matters




Spherical roller bearing

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

2. Before adding the grease to the bearing before the bearing is installed, the grease must be clean and proper.

3. When installing, do not directly hammer the inside, the outer ring end face and the roller are appropriate, so as not to crack the inner ring or the middle and small ribs. Usually the user should install the spindle immediately when the bearing is placed in mineral oil and heated to 90°-100°. It is forbidden to use local burning method for the bearing. When it is difficult to "hot install", the user should also install it with a special sleeve.

4. The bearing should have good sealing and dustproof device and lubrication, and it should not be cut off.

5. The bearing warehouse should be clean and dry, no environmental pollution, the bearing stacking will not land, and the packaging will not be damaged. Bearings that have been in stock for more than one year must be re-cleaned and oiled.

Fourth, thrust spherical roller bearing installation matters



Thrust spherical roller bearing

1. When installing the bearing, clean the bearing oil seal and apply clean high quality lubricant.

2. When installing the bearing, it should be evenly stressed and cannot be hammered. If the interference is large, the bearing should be placed in mineral oil and heated to 90°-100°, and installed immediately.

3. The warehouse where the bearings are stored should be clean and clean, and the relative humidity should not exceed 65%.

4. The stock bearing should be re-cleaned once every other year, and the oil seal package is kept in good condition.

5. When using the bearing, there should be a good seal and dustproof device, and the work should be checked frequently.

Five, cylindrical roller bearing installation matters



Cylindrical Roller Bearings

1. The bearing is of a separate type, and the user can adjust the clearance according to the needs when installing.

2. Before using the bearing, clean it with gasoline or kerosene and keep it well lubricated.

3. When the bearing is installed, the bearing should be pressed into the part and it is forbidden to knock.

4. Bearing storage should be clean and ventilated to avoid moisture. Bearings that need to be stored for a long time should be regularly rust-proof.

Sixth, thrust ball bearing installation matters



Thrust ball bearing

1. When installing the bearing, remove the bearing seal, wash it and apply clean high quality lubricant.

2. When installing the bearing, it should be evenly stressed and cannot be hammered. If the interference is large, the bearing should be placed in mineral oil and heated to 90°-100°, and installed immediately.

3. The warehouse where the bearings are stored should be clean and clean, and the relative humidity should not exceed 65%.

4. The stock bearing should be re-cleaned once every other year, and the oil seal package is kept in good condition.

5. When using the bearing, there should be a good seal and dustproof device, and the work should be checked frequently.
