SG400AR0 Bearing Product Overview & Core Advantages
The SG400AR0 is a stainless steel thin-section angular contact ball bearing designed for applications requiring high precision and corrosion resistance. This single-row bearing excels in handling combined loads, particularly significant axial loads in one direction due to its specific 30° contact angle. Manufactured to ABEC-1 precision tolerances, it delivers reliable performance in demanding environments while offering excellent resistance to corrosion through its stainless steel construction. Its compact thin-section design (1" width with 40" bore) makes it ideal for space-constrained applications where weight reduction is critical.

| SG | Stainless Steel construction for corrosion resistance |
| 400 | Bore diameter of 40 inches |
| A | 30° contact angle design |
| R0 | Standard radial clearance (0.0000 – 0.0005") |
SG400AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With only 1" width and minimal cross-section, this bearing provides significant space and weight savings while maintaining structural integrity. The stainless steel construction of both rings and balls ensures excellent corrosion resistance in harsh environments.
High Load Capacity: The 30° contact angle and optimized raceway geometry enable superior axial load capacity (55,440 lbf static) while maintaining substantial radial load capacity (19,153 lbf dynamic). The brass cage provides excellent durability and guidance under high-speed conditions.
Precision Performance: Manufactured to ABEC-1 tolerance class with tight dimensional control, this bearing ensures smooth operation and minimal runout. The precise radial internal clearance (0.0000 – 0.0005") guarantees consistent performance across various operating conditions.
Temperature Compatibility: Operating temperature range of -30°C to 110°C makes it suitable for diverse industrial environments while maintaining dimensional stability and lubrication effectiveness.
