KF090XP3 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The optimized raceway geometry allows the bearing to support combined radial and axial loads in any direction, making it ideal for complex loading conditions.
Ultra-Thin Cross-Section: With a width of only 0.75" and large 9" bore diameter, this thin section bearing provides maximum space savings while maintaining structural integrity.
Precision Engineering: Manufactured to ABEC 3F tolerance class with tight dimensional control (±0.0012") and minimal radial internal clearance (0.0000-0.0005") for precise positioning applications.
High Load Capacity: Delivers exceptional dynamic load ratings (6,947 lbf radial, 11,030 lbf axial) and static load ratings (11,000 lbf radial, 27,510 lbf axial) despite its slim profile.
Premium Materials: Constructed with chrome steel rings and balls with a brass cage for durability, corrosion resistance, and reliable performance across a wide temperature range (-30°C to 110°C).
KF090XP3 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring compact, high-precision bearings
- Aerospace and Defense: Radar systems, satellite mechanisms, and aircraft control surfaces
- Medical Equipment: CT scanners, MRI machines, and surgical robotics where space constraints and precision are critical
- Machine Tools: Rotary tables, indexing heads, and precision spindles
- Semiconductor Manufacturing: Wafer handling equipment and precision positioning stages
