KB080XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry allows the bearing to support combined radial and axial loads in any combination, providing exceptional versatility in a single-row design.
- High Rigidity & Load Capacity: Despite its thin cross-section, the bearing delivers a high static load rating of 3370 lbf radial and 8430 lbf axial, ensuring stable performance under significant load moments.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance of 0.0000 – 0.0005 inches, guaranteeing smooth, low-vibration operation.
- Durable Construction: Features chrome steel rings and balls with a brass cage for superior strength, corrosion resistance, and reliable performance across a wide temperature range (-30°C to 110°C).
- Weight Optimization: At just 0.57 lbs, it significantly reduces rotational inertia, making it ideal for high-speed applications and systems where weight savings are critical.
KB080XP0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, robotic arms, and precision positioning systems requiring compact, high-capacity bearings.
- Aerospace & Defense: Gimbals, radar systems, and control surface actuators where weight and space are at a premium.
- Medical Equipment: CT scanners, MRI machines, and surgical robots demanding high precision and reliability.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that operate in cleanroom environments.
- Optical & Instrumentation Systems: Telescope mounts, rotary tables, and other precision instruments requiring minimal deflection and smooth motion.
