KF300XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to handle combined radial, axial, and moment loads efficiently, providing versatile load-carrying capability in a single bearing.
Thin-Section Construction: With a compact cross-section of only 0.75" width and minimal wall thickness, this bearing maximizes space utilization while maintaining structural integrity.
Premium Material Composition: Manufactured from chrome steel rings and balls with a brass cage, ensuring dimensional stability, wear resistance, and reliable operation under demanding conditions.
High Load Capacity: Exceptional dynamic and static load ratings (Radial dynamic: 13,065 lbf, Axial dynamic: 23,720 lbf) combined with a rated load moment of 150 ft-lbf deliver robust performance in challenging applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005"), ensuring consistent performance and smooth operation.
KF300XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems
