| KB | Manufacturer series designation for thin-section bearings |
| 090 | Bore diameter: 9 inches |
| X | Cross section designation |
| P0 | Standard precision grade (equivalent to ABEC-1) |
KB090XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support substantial combined loads (radial, axial, and moment loads) with a single bearing row, providing exceptional load capacity in minimal space.
Thin-Section Construction: With a compact cross-section of only 0.3125" width, this bearing delivers maximum performance in applications where space and weight are critical constraints.
Premium Material Composition: Constructed with chrome steel rings and balls combined with a brass cage for optimal strength, durability, and stable operation under varying load conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (±0.0012" on diameters) ensuring consistent performance and easy installation.
Optimized Load Ratings: Engineered to handle dynamic load moments up to 6 ft-lbf with substantial radial dynamic load capacity (1732 lbf) and axial dynamic load capacity (2880 lbf).
KB090XP0 Bearing Typical Application Areas
The KB090XP0 thin-section four point contact bearing is ideally suited for:
- Robotics and Automation: Robotic joints, rotary actuators, and precision positioning systems
- Aerospace Systems: Aircraft control mechanisms, satellite positioning systems, and aerospace instrumentation
- Medical Equipment: CT scanners, MRI systems, and surgical robot joints requiring precise movement
