KF140CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With only 0.75" width and minimal cross-section, this bearing enables compact machinery design while maintaining structural integrity. The optimized geometry provides maximum load capacity within minimal space constraints.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, combined with a brass cage, ensures excellent wear resistance and dimensional stability. This material combination delivers reliable performance under the specified temperature range of -30°C to 110°C.
High Load Capacity: The radial dynamic load rating of 6620 lbf and static load rating of 16650 lbf demonstrate robust performance capabilities for demanding applications. The optimized raceway geometry distributes stresses evenly, extending service life.
Precision Engineering: Featuring ABEC-1 tolerance class with tight dimensional controls (bore tolerance: -0.0016" to 0", width tolerance: +.000 to -.010") ensures consistent performance and reliable operation in precision mechanisms.
KF140CP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring compact, high-precision bearings
- Aerospace Systems: Control mechanisms, actuation systems, and instrumentation where weight savings are critical
- Medical Equipment: Imaging systems, surgical robots, and diagnostic equipment demanding precision and reliability
- Semiconductor Manufacturing: Wafer handling equipment, precision stages, and cleanroom applications
