1.Storage

1. The new roller system or backing bearing should not destroy the inner packaging and be stored in boxes. 

2. The roller bearings that are to be reused should be thoroughly cleaned and then coated with anti-rust oil before being packaged and stored. 

3. The warehouse should be dry and dust-free. Do not allow it to get damp.

2.Disassembly

1. The dismantling site is clean and dust-free. 

2. Remove the end cover of the shaft. Then, sequentially remove the spacer sleeve or gear, saddle, key, bearing, etc. components. Do not remove the last gear or spring clip. Arrange them in an orderly manner for easy installation. 

3. The end face of the bearing outer diameter is marked with a number. During disassembly, it is strictly prohibited to mix the components. Special attention should be paid to the rolling elements, and the middle column consists of long rollers.

3.Installation

1. Before installation, the group bearings should be cleaned to remove oil and dust impurities. 

2. If installation is difficult and requires knocking, use a copper hammer to gently tap; do not use iron tools for heavy strikes. 

3. Remove any burrs or foreign objects from the shaft, saddle seat or roller box and other related parts. Use a high-pressure air duct to blow out the impurities in the oil holes and check whether each oil hole is unobstructed. Check the thickness of the bakelite thrust stopper plate. If it is too thin, replace it immediately. 

4. The saddles and bearings in the same group should be installed in sequence according to their serial numbers. The sequence numbers must not be mixed up. The numbering of the saddles should point towards the transmission side to avoid affecting the force distribution. Pay attention to the arrow position on the end face of the inner ring of the bearings. 

5. When re-installing the bearing inner ring, it should be rotated in the same direction by 90 degrees, avoiding the area where the previous load was applied. This is beneficial for extending the service life of the inner ring. 

6. After the bearings are installed, rotate each set of bearings by hand to check if the rotation is smooth and flexible. There should be no sticking or other abnormal phenomena. If any such issues occur, remove the bearings for further inspection to determine the cause of the problem. 

7. Before installation, check whether the surface of the flower-shaped hole is smooth.

4.The use of roller systems

1. When starting the machine, the lubrication system should be started first and idle for several minutes. 

2. The lubricating oil should be clean and sufficient, and the flow rate and velocity must meet the design specifications of the rolling machine. 

3. The roller system is used for one cycle (approximately 25 days). After the system is taken out of the machine, the bearings are cleaned and inspected. Any abnormalities are dealt with promptly. 

4. When abnormal situations such as belt breakage or sticking occur frequently, the replacement time of the roller system should be shortened, and the condition of the saddle bearing should be checked to see if it is damaged. 

5. The rolling process is reasonable, avoiding rough handling.

5.Rolling system maintenance

1. The supporting roller system must be managed by a special person to establish an account. Record which rolling machine has which set of saddle seats, which set of bearings, the time of installation and the time of removal, etc. 

2. The roller system must be taken off the machine at regular intervals, regardless of whether any problems occur. 

3. After unloading and disassembly, inspect each component of the roller system one by one. If any problems are found, address them promptly. 

4. After the backrest bearing is machined and disassembled, it must be stored for one cycle before being reinstalled and used again. If possible, the bearing can be removed from the machine or repaired, then placed in an oil bath at 80° - 100° for 24 hours to relieve the stress. 

5. After the bearing has been in use for some time, there may be some dents, scratches, or other defects on the outer diameter. At this point, the outer diameter should be promptly ground to remove these defects. After grinding, it is necessary to recheck and reassemble before it can be used again. The amount of grinding for the bearing depends on the specific situation. The grinding should mainly ensure that the T value and radial runout requirements of the same group are met. The measurement of the T value of the bearing cross-section height should be done using a dedicated instrument. 

6. During the installation, disassembly, cleaning and maintenance processes of the bearings, it is strictly prohibited to mix and match different types of bearings. It is also not allowed to use different bearing components randomly. The saddle seat must not be used in mixed groups. 

7. In a set of bearings, if there are damaged bearings, it is not allowed to simply replace them with another one at random. The bearing pairs need to be inspected. The height difference between the sections of the same group is less than 0.005mm, and they are distributed in a convex shape. 

8. Avoid using magnetic lifting equipment to handle the roller system. 

9. The ABCD rollers should be fitted with new or intact bearings. The rollers with slightly defective bearings should be used for the EFGH rollers.
