KG070XP0 Bearing Product Overview & Core Advantages
The KG070XP0 is a high-performance thin section bearing designed for applications requiring precision and space optimization. As a Four Point Contact ball bearing, it excels at handling combined loads—simultaneously supporting significant radial, axial, and moment loads in a compact cross-section. Its inch-series dimensions (7" bore, 9" OD, 1" width) and ABEC-1 precision make it ideal for high-accuracy rotary systems where rigidity and reliable performance are critical.
KG070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG070XP0 | Manufacturer's specific model designation for this thin section, four-point contact bearing series. |
| Open | No integral seals or shields, allowing for custom lubrication schemes and maximum speed capability. |
| Four Point Contact | The ball raceway geometry is designed to support radial, axial, and moment loads simultaneously in a single row. |
| Lubricated | The bearing is supplied with a factory-applied lubricant suitable for initial operation. |
KG070XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity in a Slim Profile: The Four Point Contact design and single row construction enable this thin section bearing to handle a high Dynamic Load Moment of 30 ft-lbf and substantial Axial Static Load (32,830 lbf) despite its minimal cross-section, providing exceptional strength-to-size ratio.
- Enhanced Rigidity and Precision: Manufactured to ABEC-1 tolerance standards with tight dimensional controls on bore, outside diameter, and width. This ensures smooth, precise rotation with minimal runout, which is critical for accurate positioning systems.
- Robust Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage offer excellent durability, wear resistance, and reliable performance under high-stress conditions.
- Versatile Operating Range: With a specified operating temperature range from -30°C to 110°C and a controlled radial internal clearance, the bearing maintains stable performance across various environmental conditions.
KG070XP0 Bearing Typical Application Areas
This bearing is engineered for use in precision machinery and systems where space and weight are at a premium. Key applications include:
- Robotics and Automation: Rotary joints, robotic arms, and precision gearing systems.
- Aerospace and Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
