Flange Integrated Bearing
Flange-integrated bearings combine the flange and the bearing outer ring into a single integrated structure.
In this design, the flange acts as the mounting and positioning reference, eliminating outer ring press-fitting and improving compactness, assembly consistency, and operating stability.
This structure can be applied to various bearing types, such as deep groove ball bearings and crossed roller bearings, and can be tailored to different precision and load requirements.

- Flange Outer Diameter (D2): 38–88 mm
- Flange Width (B1): 2–6 mm
Addressing Problems
In traditional designs, bearings typically need to be press-fitted into separate flange housings before being used as a component. This structural form introduces a series of engineering limitations in practical applications.

Compact and Lightweight Design
In flanged integrated bearings, the flange is part of the bearing outer ring, so overall size is determined by function alone. This design integrates support and mounting in a compact space, reducing impact on weight and size.
In conventional designs, an extra flange housing increases size and weight without improving performance, negatively affecting dynamics and space usage.
Stable, Consistent Performance
Flanged integrated bearings avoid radial press-fitting, so internal clearance and rolling conditions depend only on the bearing’s design. This ensures stable noise, temperature, and concentricity across batches.
In traditional bearing + flange setups, press-fitting deforms the outer ring and tolerance variations amplify inconsistencies, requiring higher machining accuracy and increasing cost.


Designs for Any Demand
Flanged integrated bearings allow optimization of rolling element size and raceway design without enlarging the overall structure, supporting higher load and longer life.
Traditional bearing + flange designs limit such adjustments, making it harder to improve load capacity or service life.
Applications
Shaft End Support and Positioning Systems
In a wide range of mechanical equipment, rotating shafts are required to provide both support and axial positioning at the shaft ends, placing high demands on concentricity. Insufficient concentricity introduces radial runout during rotation, adversely affecting operating accuracy and stability.
Rotational Support Units in Robotic Joints
Robotic joints are typically constrained by limited installation space, strict weight limits, high precision requirements, and increasing load demands. Integrating the flange structure with the bearing inner or outer ring helps reduce part count and structural layers.
