A combined bearing is a specialized bearing unit that ingeniously integrates two or more bearing structural forms (such as needle/cylindrical rollers and thrust ball bearings) into a single assembly. Its core design concept is to simultaneously accommodate multiple combined loads-including radial loads, axial loads, and overturning moments-within a compact component.

Its primary functions include:
Simplifying structure: Replacing traditional multi-bearing configurations, significantly saving installation space and resulting in a more compact equipment design.
Enhancing precision and rigidity: The integrated design minimizes cumulative tolerances, providing superior system rigidity and rotational accuracy.
Improving reliability: Factory pre-adjustment and centralized lubrication simplify installation and maintenance, thereby enhancing overall operational stability and service life.
Application requirements are stringent, particularly in the following areas:
Application fields: Widely used in scenarios requiring high precision and rigidity within limited space, such as machine tool spindles, industrial robot joints, precision speed reducers, metallurgical equipment, and the slewing mechanisms of construction machinery.
Key requirements:
Precise selection: Bearing types and configurations must be accurately selected based on actual operating conditions (load type and magnitude, rotational speed, and precision class).
Precision installation: There are extremely high requirements regarding dimensional tolerances, geometric tolerances, and surface roughness of the mating surfaces; professional tools and strict procedures are essential.
Proper lubrication and sealing: Appropriate lubricants and effective sealing solutions must be employed to ensure performance and prevent contamination.
Strict control of operating conditions: Operation must remain within the designed limits for load, speed, and temperature rise to avoid overloading.
