KA080AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides superior stiffness and can support substantial combined radial and axial loads (Radial Dynamic: 890 lbf, Axial Static: 2280 lbf).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (Bore/OD tolerance: -0.0012" to 0") for smooth, accurate operation in precision assemblies.
- Optimized Material Selection: Components made from Chrome Steel (rings and balls) and a Brass cage ensure durability, corrosion resistance, and stable performance across a wide temperature range (-30°C to 110°C).
- Space-Saving Design: As a thin section bearing (Width: 0.25"), it maximizes design space efficiency while maintaining high load ratings, crucial for compact machinery.
KA080AR0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, actuator arms, and precision positioning systems requiring high rigidity and compact bearing dimensions.
- Aerospace & Defense: Guidance systems, radar platforms, and instrumentation where combined loads and reliability are critical.
- Medical Equipment: Imaging devices (CT/MRI scanners) and surgical robots demanding ABEC-1 precision and smooth motion.
- Industrial Machinery: Rotary tables, indexing heads, and other precision machinery utilizing angular contact ball bearings for accurate axial and radial support.
