Tapered roller bearing can bear radial and axial load at the same time. It is composed of two outer rings, one spacer ring, and one inner sleeve assembly. Bearing manufacturing clearance has been adjusted with spacers according to user working conditions and national standards when the products leave the factory. Users only need to install it according to the correct operating procedures.
Two. After the tapered roller bearings arrive at the installation site, open the packaging and check whether the bearings are corroded by moisture or bumped during transportation.
3. Tapered roller bearings are rust-proof with soluble water agents, and there is no chemical change in contact with different grease, and no deterioration reaction will occur.
Four. Installation steps of tapered roller bearings:
Clean the bearing box seat hole, roll neck, and gland with clean kerosene, and check whether there are burrs or bumps in the contact parts with the bearing. If there are, polish them with an emery cloth or grinder. When checking the bearing box seat hole, in addition to checking whether its shape and position size are out of tolerance, it is also necessary to check the corresponding position of the two outer rings installed in the load area to see whether there is an obvious boss between the two outer rings. If the size is out of tolerance and there is an obvious boss, it is recommended to replace the new bearing box.
Measure the actual height of the bearing, measure the height of the gland protruding mouth, and calculate the maximum value of the gasket required in combination with the net height of the bearing box. (H1+H2+B-L)/2=X thickness of the gasket

First, one side of the gland of the bearing box is installed, which is turned flat on the platform, and then the first outer ring, spacer ring, inner sleeve assembly, and the second outer ring are installed in turn. In this process, the inner ring should be rotated continuously to ensure that the end face of the first outer ring is compact with the gland, the raceway is well fitted with the first row of rollers, and the gland on this site is installed. Rotate the inner ring of the bearing by hand to check whether there is stagnation or jam. If it is intact, seal the hole of the bearing box seat and put it in the spare area.
Five, the roller has been installed on the bearing box, combined with the axial clearance of the bearing, a certain value of gap E is reserved between the end face of the bearing inner sleeve and the end face of the pressure sleeve, which is very important, it can ensure that the bearing work, the load can be evenly distributed to the two rows of the rolling body to the maximum extent.
The work of adding grease can be interwoven in one of the above links or filling online according to the needs of the production line.
VII. Special Notes:
Whether the roughness of the parts in contact with the lip of the seal on the roller system meets the requirements.
Whether there is enough interference installed on the roller in the moving maze fitting with the end face of the roller, otherwise, it will be displayed in the use of the bearing, causing the end face of the inner ring of the bearing to wear, and radial radiation cracks appear on the end face of the bearing in serious cases.
After the bearing is used online for a period of time, according to the working conditions, the load area of the two outer rings of the bearing is adjusted by 90°~120°, which can effectively prolong the service life of the bearing.
