KA045XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized raceway geometry creates four contact points between balls and raceways, enabling the bearing to handle combined radial, axial, and moment loads efficiently in a single compact unit.
Thin-Section Construction: With a consistent 0.25" cross-section and large 4.5" bore diameter, this bearing provides maximum load capacity while minimizing space requirements and weight (only 0.22 lbs).
Premium Material Composition: Constructed with chrome steel rings and balls combined with a brass cage for superior strength, durability, and stable operation under varying load conditions.
High Load Capacity: Delivers exceptional radial dynamic load rating of 809 lbf and axial dynamic load rating of 1310 lbf, with static capacities reaching 1440 lbf radial and 3600 lbf axial.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0008" to 0") for consistent performance in precision applications.
KA045XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring high stiffness and compact design
- Aerospace and Defense: Radar systems, gimbal mechanisms, and satellite positioning equipment
- Medical Equipment: CT scanners, MRI machines, and surgical robotics where precision and reliability are critical
