KA070XP0 Bearing Product Overview & Core Advantages
The KA070XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, engineered for applications demanding high load capacity in a compact, thin-section design. This single row bearing is uniquely designed to simultaneously support significant combined radial and axial loads from any direction, making it an ideal solution for space-constrained, high-precision machinery. Manufactured to ABEC-1 precision and pre-lubricated, it offers reliable performance and long service life in demanding operational environments.
KA070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA070 | Indicates the specific bearing series and size designation within the Reali-Slim family. |
| XP0 | Signifies an Open (unsealed) construction and specific internal configuration for four-point contact. |
KA070XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry allows the bearing to handle combined radial and axial loads efficiently, providing versatility in load support from multiple directions.
- Thin-Section & Lightweight: With a cross-section of just 0.25", it offers significant space and weight savings (only 0.31 lbs) without compromising on load capacity.
- High Load Ratings: Engineered for high dynamic and static load capacity (Radial Dynamic: 1046 lbf, Axial Dynamic: 1730 lbf), ensuring durability under strenuous conditions.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance (0.0000" – 0.0005") for smooth, precise operation.
- Robust Material Construction: Features Chrome Steel rings and balls with a Brass cage for high strength, corrosion resistance, and operational stability.
- Pre-Lubricated: Comes lubricated from the factory, ready for immediate installation and initial operation.
KA070XP0 Bearing Typical Application Areas
- Robotics: Joint and actuator bearings in robotic arms requiring compact size and high moment load capacity.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms where precision and reliability are critical.
- Medical Equipment: Scanning and imaging devices, surgical robots demanding high precision and smooth motion.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Industrial Automation: Rotary tables, indexing heads, and other precision motion control systems.
