Installation instructions for various bearings
Rolling bearing instructions
1. When installing the bearing, the force should be uniform and should not be hammered directly. For example, if the fit 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°. They should not work for more than 4 hours at 150°, and the short-term temperature peak can reach 180°.
3. The warehouse where bearings are stored should be clean, dry and not allowed to be stored in the same warehouse as chemical products. The relative humidity should not exceed 65%, and bearings are not allowed to be stored on the floor.
Installation and use of deep groove ball bearings
1. When installing the bearing, the force should be uniform and should not be hammered directly. For example, if the fit 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 operate continuously and stably for a long time at -40°~120°. The operation at 150° should not exceed 4 hours, and the short-term temperature peak should not exceed 180°.
3. The warehouse where bearings are stored should be clean, dry and not allowed to be stored in the same warehouse as chemical products. The relative humidity should not exceed 65%, and bearings are not allowed to be stored on the floor.
4. Bearings in stock should be re-cleaned every other year and packed in anti-rust packaging.
Angular contact ball bearing installation and use
1. When installing the bearing, the force should be uniform and should not be hammered directly. For example, if the fit 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°. The operation at 150° should not exceed 4 hours, and the short-term temperature peak can reach 180°.
3. The warehouse where bearings are stored should be clean, dry and not allowed to be stored in the same warehouse as chemical products. The relative humidity should not exceed 65%, and bearings are not allowed to be stored on the floor.
Installation and use of spherical roller bearings
1. Users should select appropriate fits and bearing clearances according to usage requirements. Please proofread the bearing code first 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. During installation, it is advisable not to directly hammer the inner and outer ring end faces and rollers to avoid cracking the inner ring or the middle and small ribs. Usually the user should put the bearing in mineral oil and heat it to 90°~100° and install it on the spindle immediately. Do not use local spray burning method on bearings. When it is difficult to “hot install”, users should also use special sleeves to install them.
4. The bearing should have good sealing and dust-proof device and lubrication during use, and the oil should not be cut off.
5. The bearing warehouse should be clean and dry, without environmental pollution, the bearings should not be stacked on the ground, and the packaging should not be damaged. Bearings that have been in stock for more than one year must be re-cleaned and oiled.
Installation and use of thrust spherical roller bearings
1. When installing the bearing, the bearing oil seal should be cleaned and then coated with clean high-quality lubricating oil.
2. When installing the bearing, the force should be uniform and no hammering should be allowed. If the fit interference is large, the bearing should be placed in mineral oil and heated to 90°~100° before installation immediately.
3. The warehouse where bearings are stored should be clean and tidy, with a relative humidity not exceeding 65%.
4. Bearings in stock should be re-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 dust-proof devices, and the working conditions should be checked frequently.
Cylindrical roller bearing installation and use
1. This bearing is a separate type, and the user can adjust the clearance as needed during installation.
2. Before use, the bearings should be cleaned with gasoline or kerosene and kept well lubricated.
3. When installing the bearing, 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 rust-proofed regularly.
Installation and use of thrust ball bearings
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 no hammering should be allowed. If the fit interference is large, the bearing should be placed in mineral oil and heated to 90°~100° before installation immediately.
3. The warehouse where bearings are stored should be clean and tidy, with a relative humidity not exceeding 65%.
4. Bearings in stock should be re-cleaned and oiled every other year, and the oil seal packaging should be kept in good condition.
