SD050AR0 Bearing Product Overview & Core Advantages
The SD050AR0 is a thin section angular contact ball bearing designed for applications requiring exceptional precision and space optimization. As part of the Reali-Slim Stainless Steel Bearings series, it delivers reliable performance in compact designs. This single row bearing excels at handling combined loads, particularly thrust loads in one direction, thanks to its defined 30° contact angle. Manufactured with stainless steel rings and balls with a brass cage, it offers excellent corrosion resistance and smooth operation. Its ABEC-1 precision and consistent performance make it ideal for high-reliability applications where dimensional stability is critical.

SD050AR0 Bearing Structural Features & Performance Benefits
Thin Section Design: With a cross-section of only 0.5" despite its large 5" bore diameter, this bearing enables space-saving solutions without compromising performance. The optimized geometry provides maximum load capacity within minimal envelope dimensions.
Angular Contact Configuration: The 30° contact angle is specifically engineered to handle significant axial loads in one direction while simultaneously supporting radial loads. This makes it particularly suitable for applications with combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls, ensuring consistent performance and reliable operation in precision mechanisms. The brass cage provides excellent guidance and stability at various operating speeds.
Material Excellence: Constructed entirely from stainless steel components, offering superior corrosion resistance and making it suitable for harsh environments, food processing, and medical applications where contamination must be avoided.
