Dong WeiliangThis type of bearing can bear radial and axial loads 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 spacer ring according to user's working condition and national standard when the product leaves the factory. The user only needs to install according to the correct operation regulations. 2、 After the bearing is transported to the installation site, open the package and check whether the bearing is damp, rusted or collided during transportation. 3、 Soluble water agent is used for anti rust of bearing, and there is no chemical change in contact with different lubricating grease, and no deterioration reaction will occur. 4、 Bearing installation steps:
Clean the bearing housing seat hole, roll neck and gland with clean kerosene, and check whether there are burrs and bumps in the contact parts with the bearing. If so, polish them with abrasive cloth or polishing machine. When checking the bearing housing seat hole, in addition to checking whether the shape and position dimensions 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 whether there is obvious boss between the two outer rings. If the size is out of tolerance and there is obvious boss, it is recommended to replace the bearing housing with a new one. 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 required gasket combined with the clear height of the bearing box. (H1 + H2 + B-L) / 2 = x & nbsp; gasket thickness & lt; X. First, install one side of the bearing housing gland, turn it over and place it on the platform, and then install the first outer ring, spacer ring, inner sleeve assembly and the second outer ring in turn. In this process, the inner ring should be continuously rotated to ensure that the end face of the first outer ring is close to the gland, and its raceway fits with the first row of rollers. Install the gland on this side. Rotate the inner ring of the bearing by hand to check whether there is stagnation and jamming. If it is in good condition, seal the bearing housing seat hole and put it in the spare area. 5、 The roller with movable labyrinth is installed on the bearing box. Combined with the axial clearance of the bearing, it is important to reserve a certain value of gap e between the end face of the bearing inner sleeve and the end face of the pressing sleeve, which can ensure that the load can be evenly distributed to the two rows of rolling elements as much as possible when the bearing is working. 6、 According to the needs of the production line, grease can be added alternately in one of the above links or online filling. 7、 Special precautions: Whether the roughness of the part contacting with the seal lip on the roller system meets the requirements. If there is enough interference in the labyrinth which fits the roller end face, it will cause displacement in the use of the bearing, resulting in wear of the inner ring end face of the bearing, and in serious cases, radial radial radial cracks appear on the end face of the bearing. 8、 Suggestions: After the bearing has been on-line for a period of time, the load area of the two outer rings of the bearing can be adjusted by 90-120 & deg; according to the working conditions, which can effectively prolong the service life of the bearing.
