KG070XW0 Bearing Product Overview & Core Advantages
The KG070XW0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered for applications demanding compact design and high load capacity within minimal cross-sections, this bearing excels at simultaneously handling combined radial loads and axial loads from both directions. Its ABEC-1 precision and optimized internal geometry ensure reliable operation in high-rigidity systems, making it an ideal solution for space-constrained, precision machinery.
KG070XW0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| KG070XW0 | Specific model identifier for this thin section bearing | Unique product designation |
| Open | No seals or shields | Allows for custom lubrication schemes and easy maintenance access |
| Four Point Contact | Ball-raceway contact geometry | Enables single bearing to support combined radial and axial loads |
| Lubricated | Factory-applied lubricant | Reduces initial friction and provides immediate operation readiness |
KG070XW0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique ball-to-raceway contact at four points allows this single-row bearing to effectively manage combined loads, replacing the need for more complex bearing arrangements in many applications.
- High Load Capacity: With a radial dynamic load rating of 10,208 lbf and an axial dynamic load rating of 15,400 lbf, it delivers exceptional performance despite its slim 1" cross-section.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth operation and accurate positioning.
- Premium Material Construction: Chrome Steel rings and balls combined with a Stainless Steel cage provide excellent durability, corrosion resistance, and long service life.
- Temperature Resilience: Operates effectively across a temperature range of -30°C to 110°C, suitable for various industrial environments.
KG070XW0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning tables requiring high rigidity in compact spaces
- Aerospace Systems: Actuators, control mechanisms, and satellite positioning systems
- Medical Equipment: CT scanners, MRI machines, and surgical robotics where precision and reliability are critical
- Semiconductor Manufacturing: Wafer handling equipment, precision stages, and inspection machinery
