KF350AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides superior stiffness and is engineered to support high combined radial and axial loads. The substantial static load moment rating of 139,700 lbf ensures stability under complex loading conditions.
- Precision & Speed: Manufactured to ABEC-1 tolerance standards with a brass cage for stability, this bearing supports smooth operation and is suitable for high-speed applications.
- Thin-Section Design: With a compact cross-section (0.75" width) and large bore (35"), the KF350AR0 saves significant space and weight, a critical advantage in aerospace and robotics.
- Material & Construction: Components made from chrome steel offer high durability and wear resistance, ensuring long service life in demanding environments.
KF350AR0 Bearing Typical Application Areas
- Aerospace & Defense: Radar systems, gimbal mounts, and flight control mechanisms.
- Industrial Robotics: Robot arm joints, rotary tables, and precision actuators.
- Medical Equipment: CT scanners, MRI machines, and surgical robot arms.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical & Instrumentation: High-precision rotary stages and telescope mounts.
