Assembly technical standards and methods of roller bearings

Assembly technical standards for roller bearings:

　　1. The inner hole containing the identification number on the roller bearing must be installed in the visible position for easy checking when disassembling and replacing.

　　2. After the rolling bearing is installed on the shaft or into the bearing hole of the belt seat, it is not allowed to tilt.

　　3. Among the two rolling bearings with coaxial output, one rolling bearing must have a space for radial movement when the shaft is heated and deformed.

　　4. When assembling the rolling bearing, the interaction force should be added to the end surface of the ring to be matched with each other immediately, and it is not allowed to transmit the working pressure according to the turning body.

　　5. Keep clean during the whole assembly process to prevent dirt from entering the rolling bearing.

　　6. The assembled rolling bearing should run flexibly, with low noise, and the temperature rise during work should not exceed the control value.

Assembly method of roller bearing:

　　 Roller bearings have the advantages of small friction, small radial specifications, convenient disassembly and replacement, and simple maintenance. When assembling a rolling bearing, the most basic requirement is to make the added axial force immediately act on the end surface of the ring of the installed rolling bearing. Do not harm the flip body as much as possible.

    What is the difference between roller bearing and sliding bearing in structure and movement mode? The most significant difference between rolling bearings and sliding bearings depends on whether there are rolling elements.

    Rolling bearings have rolling elements (balls, cylindrical roller bearings, tapered roller bearings, needle rollers), which rely on their rotation to support the point of rotation axis, so the contact part is a point, the more rolling elements, the greater the point contact .

    The sliding bearing does not have rolling elements, and relies on a smooth surface to support the point of rotation axis, so the contact part is a surface.

    The difference of the two structures determines that the motion mode of the rolling bearing is rolling, and the motion mode of the sliding bearing is dragging, so the friction situation is completely different.

    Roller bearings and sliding bearings are well distinguished in terms of structure and movement mode. Our company produces various types of bearings. In case of specific situations, we can also customize bearings. Dahang bearings, bearing manufacturers around you.
