1. This type of bearing can bear radial and axial loads at the same time, and consists of two outer rings, one spacer ring and one inner sleeve assembly. The bearing manufacturing clearance has been adjusted by the spacer according to the user's working conditions and with reference to the national standard when the product leaves the factory. The user only needs to install it according to the correct operating procedures.
2. After the bearing arrives at the installation site, open the package and check whether the bearing is damp and corroded, or bumped during transportation.
3. The rust prevention of the bearing adopts soluble water agent, and there is no chemical change in contact with different greases, and no deterioration reaction occurs.
4. bearing installation steps:
Use clean kerosene to clean the bearing box seat hole, roll neck and gland, and check whether there are burrs or bumps in the contact parts with the bearing. When checking the bearing box seat hole, in addition to checking whether its shape and size are out of tolerance, it is also necessary to check the corresponding positions of the two outer rings installed in the load area to see if there are obvious bosses between the two outer rings. Out of tolerance and there are obvious bosses, it is recommended to replace the new bearing housing.
Measure the actual height of the bearing, measure the height of the gland protruding from the sub-port, and calculate the maximum value of the gasket required in combination with the clear height of the bearing box. (H1+H2+B-L)/2=X Gasket thickness<X.
First install one side gland of the bearing box, turn it over and lay it flat on the platform, and install the first outer ring, spacer, inner sleeve assembly, and second outer ring in sequence. During this process, keep rotating the inner ring. Make sure that the end face of the first outer ring is firmly attached to the gland, its raceway is well attached to the first row of rollers, and the gland on this side is installed. Rotate the inner ring of the bearing by hand to check whether there is stagnation or jamming. If it is in good condition, seal the hole of the bearing housing and place it in the spare area.
5. Install the roll with the dynamic labyrinth installed on the bearing box, and reserve a certain amount of gap e between the end face of the bearing inner sleeve and the end face of the pressure sleeve in combination with the axial clearance of the bearing. This is very important, it can ensure When the bearing is working, the load can be evenly distributed to the two rows of rolling elements to the greatest extent.
6. The work of adding grease can be interspersed in one of the above links or online according to the needs of the production line.
7. Special attention:
Whether the roughness of the part in contact with the lip of the seal on the roller system meets the requirements.
Whether the dynamic labyrinth that fits with the end face of the roll has enough interference on the roll, otherwise, the bearing will be displaced during use, causing the end face of the inner ring of the bearing to wear, and radial radial cracks will appear on the end face of the bearing in severe cases.
8. Recommendations:
After the bearing is used online for a period of time, according to the working conditions, adjust the load zone of the two outer rings of the bearing to 90~120, which can effectively prolong the service life of the bearing.
