KB042CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent cross-section of only 0.3125" width, 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" to 0") ensures smooth operation and accurate positioning.
High Load Capacity: Despite its slim profile, the bearing delivers 846 lbf dynamic radial load rating and 1830 lbf static radial load rating, making it suitable for demanding applications.
Quality Materials: Chrome steel rings and balls combined with a brass cage provide excellent durability, corrosion resistance, and stable operation across the temperature range of -30°C to 110°C.
Optimized Internal Clearance: Radial internal clearance of 0.0000 - 0.0005" ensures precise operation with minimal vibration.
KB042CP0 Bearing Typical Application Areas
Aerospace Systems: Actuators, control mechanisms, and instrumentation where space and weight are critical factors
Robotics & Automation: Joint bearings, rotary tables, and precision positioning systems requiring thin-section solutions
Medical Equipment: Imaging systems, surgical robots, and diagnostic devices demanding high precision and reliability
