KA065XP0 Bearing Product Overview & Core Advantages
The KA065XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered with an ultra-thin cross-section (0.25" width), it delivers exceptional space and weight savings while maintaining high load capacity. Its single row design with a four-point contact geometry enables it to simultaneously support combined loads—significant radial, axial, and moment loads—making it an ideal precision bearing for compact, high-rigidity applications demanding accuracy and reliability.
KA065XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA065 | Bore diameter code for 6.5 inches |
| XP0 | Specific series designation for Reali-Slim open type bearings |
| Open | No seals or shields, allowing for custom lubrication schemes |
KA065XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry allows a single bearing to handle combined radial, axial, and moment loads efficiently, simplifying assembly and reducing the need for multiple bearing arrangements.
- Thin-Section Construction: With a consistent 0.25" cross-section, this bearing enables dramatic reductions in bearing size and overall system weight without compromising structural integrity or load capacity.
- High-Precision Components: Manufactured from Chrome Steel rings and balls with a Brass cage, the bearing ensures smooth operation, minimal vibration, and extended service life under ABEC-1 precision tolerances.
- Superior Load Ratings: Engineered for demanding applications, it offers a radial dynamic load rating of 1001 lbf and an exceptional axial static load rating of 5120 lbf.
KA065XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning stages where compact design and high moment load capacity are critical.
- Aerospace and Defense: Gimbals, radar systems, and control surfaces that require lightweight, high-performance thin section bearings.
- Medical Equipment: CT scanners, surgical robots, and imaging devices demanding smooth, precise motion in a confined space.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where high rigidity and minimal particle generation are essential.
