1. Outer Ring: The outer ring of Combined Radial-Axial Bearings is designed in a cup or sleeve shape. Its inner cylindrical surface is machined as the raceway for radial bearings, while the end face or bottom inner surface is machined as the raceway for axial bearings.
2. Inner Ring: Coaxially arranged with the outer ring, its outer cylindrical surface and cylindrical rolling elements together form the radial load-bearing portion.
3. Rolling Elements and Cage:
Radial rolling elements: Installed between the inner and outer rings to bear radial loads.
Axial rolling elements: Arranged on one or both sides of the bearing. One side of the running track is formed by the end face of the outer ring, and the other side is formed by a thrust washer.
4. Running Disk: Used to provide the running track on the other side for the axial rolling elements.
5. Cage: Used to separate and guide rolling elements, preventing them from colliding with each other.
When the shaft is subjected to radial force, this force is transmitted through the shaft to the inner ring of the Combined Radial-Axial Bearings, and then through the radial rolling elements to the cylindrical inner raceway of the outer ring.
The rolling motion of the rolling elements converts sliding friction into rolling friction, efficiently bearing radial loads with low loss.
When the shaft is subjected to axial force, the force is transmitted through steps or locating elements on the shaft to the thrust washer, and then through the axial rolling elements to the end face raceway of the outer ring.
Similarly, rolling friction ensures efficient bearing of axial loads.
The radial and axial load-bearing functions are performed independently and simultaneously within the same bearing unit, simplifying the equipment structure and avoiding the alignment errors and cumulative tolerances that may occur when installing two independent bearings separately, thus improving overall rigidity and rotational accuracy.
One Combined Radial-Axial Bearing can replace the work that originally required two separate bearings, shortening the axial dimension and reducing the overall weight of the equipment.
Utilizing BMT Bearing's advanced ultra-precision machining equipment and strict assembly processes, the runout and dimensional tolerances of this product can be controlled at the micron level, making it suitable for precision machine tools and robot joints.
For applications such as heavy-duty agricultural equipment and high-frequency vibration automated production lines, the combined bearing can also provide stable support, preventing premature failure caused by uneven stress.
Through high-quality bearing steel and advanced heat treatment processes, combined with precision cleaning and grease filling, the product has a stable service life of 2-3 years or more under normal maintenance.
