KA030XP0 Bearing Product Overview & Core Advantages
The KA030XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered with an ultra-thin cross-section (Width: 0.25"), it delivers exceptional space and weight savings without compromising load capacity. Its Four Point Contact design enables it to simultaneously support combined radial and axial loads from any direction, making it an ideal solution for compact, high-precision applications requiring high rigidity and reliable performance in a slim profile.

KA030XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact & High Rigidity: The unique raceway geometry allows the bearing to handle combined loads efficiently. The single-row design with a thin section provides high system rigidity while minimizing envelope size.
- Superior Load Capacity: Engineered for high moment load capacity (Rated Load Moment: 785 ft-lbf), it offers substantial axial static load rating (2470 lbf) and radial dynamic load rating (643 lbf), making it suitable for applications with complex loading conditions.
- Precision & Smooth Operation: Manufactured to ABEC-1 precision tolerances with a brass cage for stable operation and a tight radial internal clearance (0.0000 – 0.0005") for precise positioning.
- Material & Construction: Components made from Chrome Steel provide high durability and wear resistance, ensuring long service life under demanding conditions.
KA030XP0 Bearing Typical Application Areas
The KA030XP0's compact design and high load capacity make it ideal for:
- Robotics (Robotic arms, rotary joints)
- Aerospace & Defense (Gimbals, control mechanisms)
- Medical Equipment (CT scanners, surgical robots)
- Machine Tools (Rotary tables, indexing heads)
- Semiconductor Manufacturing Equipment
