Instructions for the 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. The bearing equipped with nylon cage can work continuously and stably for a long time at -40°-120°. It 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.

Installation and use of spherical roller bearings

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

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 to avoid cracking 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 on the bearing, and it should be well sealed and dustproof when using the bearing.

4. Lubricate, do not cut off the oil.

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.

Thrust scorpion coat

1. When installing the bearing, the bearing oil seal should be 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 bearing is stored should be clean and clean, and it is relatively far from 65%.

4. 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.

Cylindrical roller bearing installation and use

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

2. Before use, the bearing 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.

Precautions before installation ①、Preparation of bearing Since the bearing is rust-proof and packed, do not open the packing until just before installation.

In addition, the anti-rust oil coated on the bearing has good lubricating performance. For general-purpose bearings or bearings filled with grease, it can be used directly without cleaning. However, for instrument bearings or bearings used for high-speed rotation, use clean cleaning oil to wash off the anti-rust oil. At this time, the bearings are easy to rust and cannot be placed for a long time.

②. Inspection of shaft and housing Clean the bearing and housing to confirm that there are no scratches or burrs left by machining. There must be no abrasive (SiC, Al2O3, etc.) molding sand, chips, etc. in the shell.

Next, check whether the size, shape and processing quality of the shaft and housing conform to the drawings.

Before installing the bearing, apply mechanical oil to the mating surfaces of the shaft and the housing that have passed the inspection.

Installation method of bearing

The installation method of bearing varies depending on the type of shaft b and fit conditions.

Because most of the shafts rotate, the inner ring and outer ring can use interference fit and clearance fit respectively, while the outer ring uses interference fit when the outer ring rotates
