KA042CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With only 0.25" width and minimal cross-section, this bearing enables compact machinery design while maintaining structural integrity.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0008"–0") ensures smooth operation and precise positioning.
High Load Capacity: The chrome steel construction of rings and balls combined with brass cage provides a radial dynamic load rating of 591 lbf for reliable performance under radial stresses.
Optimized Clearance: Controlled radial internal clearance (0.0000 – 0.0005") ensures consistent performance across operating conditions.
Wide Temperature Range: Suitable for operations from -30°C to 110°C, making it versatile for various industrial environments.
KA042CP0 Bearing Typical Application Areas
- Robotics and Automation: Joint and pivot points in robotic arms requiring compact, lightweight bearings
- Aerospace Systems: Control mechanisms and instrumentation where space and weight are critical factors
- Medical Equipment: Precision imaging devices and surgical robots demanding high accuracy
