KD090XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support combined radial and axial loads in any direction, making it ideal for complex loading conditions. This design provides superior moment load capacity with rated load moment of 12 ft-lbf.
Thin Section Construction: With a consistent cross-section (10" OD × 9" ID × 0.5" width), this bearing maximizes space utilization while maintaining high load ratings (radial dynamic: 3561 lbf, axial dynamic: 5790 lbf).
Premium Material Selection: Constructed from chrome steel rings and balls with brass cage, the bearing ensures durability, corrosion resistance, and stable operation across the temperature range of -30°C to 110°C.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore/OD tolerance: -0.0012" to 0"), ensuring smooth operation and minimal vibration in precision applications.
KD090XP0 Bearing Typical Application Areas
- Robotics and Automation: Robot arms, rotary joints, and precision positioning systems
- Aerospace Systems: Aircraft control mechanisms, satellite positioning devices
- Medical Equipment: CT scanners, MRI machines, and surgical robotics
- Industrial Machinery: Rotary tables, indexing devices, and precision gearboxes
