SB080AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is defined by its specialized construction:
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides excellent resistance to combined loads, supporting a radial dynamic load rating of 1284 lbf and a significant axial static load rating of 3260 lbf.
- Precision & Smooth Operation: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance (0.0000 – 0.0005"), it ensures minimal vibration and high running accuracy.
- Corrosion Resistance & Durability: Both rings and balls are made from stainless steel, offering superior protection in harsh environments and a wide operating temperature range from -30°C to 110°C.
- Space-Saving Design: As part of the Reali-Slim series, it features a thin cross-section, enabling compact and lightweight machinery designs without sacrificing performance.
SB080AR0 Bearing Typical Application Areas
