KG040XP0 Bearing Product Overview & Core Advantages
The KG040XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed in inch dimensions for space-constrained, high-precision applications. This single row, open-type bearing excels at simultaneously handling combined radial and axial loads from any direction. Manufactured to ABEC-1 precision tolerances, it offers reliable operation and high rigidity in a compact, thin-section cross-section, making it ideal for applications demanding high rotational accuracy and structural efficiency.
KG040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG040 | Indicates the specific bearing series and size designation (4" bore, 6" OD, 1" width) within the Reali-Slim family. |
| XP0 | Signifies an Open (unsealed) construction, allowing for custom lubrication schemes and facilitating high-speed operation. |
KG040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry allows a single bearing row to support significant combined radial and axial loads from any direction, simplifying assembly and reducing the need for complex bearing arrangements.
- High Load Capacity: Engineered for demanding applications, it offers a substantial radial dynamic load rating of 7979 lbf and an impressive axial dynamic load rating of 11260 lbf.
- Precision & Rigidity: Built to ABEC-1 tolerance standards with a tight radial internal clearance, ensuring smooth, precise rotation and enhanced system stiffness.
- Thin-Section & Lightweight: The compact cross-section (1" width) and low weight (3.6 lbs) enable significant space and weight savings in machinery design without compromising performance.
- Durable Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage provide excellent durability, wear resistance, and reliable operation across a wide temperature range.
KG040XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, high-capacity solution:
- Robotics: Joint and actuator bearings in robotic arms and precision automation equipment.
- Aerospace & Defense: Gimbals, radar platforms, and control surface mechanisms.
- Machine Tool: Rotary tables, indexing heads, and other precision rotary components.
- Medical Equipment: Imaging scanners (CT, MRI) and surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages.
