K09020XP0 Bearing Product Overview & Core Advantages
The K09020XP0 is a Four Point Contact Ball Bearing from the Reali-Slim mm Metric Bearings series, designed for applications requiring compact cross-sections and high load capacity. This thin section bearing excels in handling combined loads, simultaneously supporting significant radial, axial, and moment loads. Its single row construction with a four-point contact design provides high rigidity and precision, making it ideal for space-constrained, high-performance machinery operating under ABEC-1 tolerance standards.

K09020XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: Enables the bearing to support combined radial, axial, and moment loads efficiently in a single, compact unit, simplifying assembly and reducing overall system size.
High Load Capacity: Engineered with a brass cage and chrome steel rings and balls, it offers a high dynamic load rating (4989 lbf radial, 7123 lbf axial) and static load rating (5452 lbf radial, 13626 lbf axial) for demanding applications.
Precision & Rigidity: Manufactured to ABEC-1 precision tolerances with controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth operation, accurate positioning, and high system rigidity.
Thin Section Profile: The slim bearing dimensions (20mm width) save space and weight (0.08 kg), ideal for compact designs without sacrificing performance.
K09020XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and arm linkages requiring high moment load capacity.
- Aerospace & Defense: Actuators, radar platforms, and guidance systems.
- Medical Equipment: CT scanners and surgical robot arms.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
