6803 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The raceway design enables efficient handling of radial loads while accommodating moderate axial loads in both directions, providing versatile load capacity in a compact form factor.
Precision Manufacturing: Built to ABEC-1 tolerance class with tight dimensional control (bore: -0.008mm to 0, OD: -0.009mm to 0), ensuring consistent performance and reliable fit in assembly.
High-Speed Capability: The combination of stainless steel cage and optimized internal geometry enables operation at limiting speeds up to 29,000 rpm, suitable for high-rotation applications.
Standard Radial Clearance: With C0 clearance (0.003mm to 0.018mm), this bearing provides optimal performance for most general applications across the operating temperature range of -30°C to 110°C.
