| XP | Four Point Contact design for combined loading capability |
| 0 | Open construction without seals |
KA020XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The optimized raceway geometry enables the bearing to support significant radial loads, axial loads in both directions, and moment loads simultaneously, making it a versatile solution for complex loading conditions.
Thin Section Construction: With a minimal cross-section (0.25" width), this bearing provides maximum space savings while maintaining structural integrity, ideal for weight-sensitive and compact applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000" – 0.0005"), ensuring smooth operation and precise positioning accuracy.
Premium Materials: Constructed with chrome steel rings, chrome steel balls, and brass cage for enhanced durability, corrosion resistance, and stable performance across the operating temperature range (-30°C to 110°C).
KA020XP0 Bearing Typical Application Areas
- Robotics & Automation: Joint bearings, rotary actuators, and precision positioning systems
- Aerospace & Defense: Guidance systems, radar platforms, and instrumentation mounts
- Medical Equipment: Surgical robots, imaging devices, and diagnostic machinery
- Semiconductor Manufacturing: Wafer handling robots and precision stages
