SD160AR0 Bearing Product Overview & Core Advantages
The SD160AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability. Constructed entirely from stainless steel with a brass cage, it is designed to handle significant combined loads, including substantial thrust loads in one direction, thanks to its specific 30° contact angle. This single-row design offers a compact solution with a large 16-inch bore in a remarkably slim 0.5-inch cross-section, making it ideal for space-constrained, high-precision assemblies requiring corrosion resistance and consistent performance.
SD160AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD | Indicates the bearing series, specifically a Reali-Slim thin-section bearing. |
| 160 | Specifies the bore diameter in sixteenths of an inch (160/16 = 16-inch bore). |
| A | Denotes the contact angle of 30°, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (C0). |
| (Open) | The bearing features an open (unsealed) construction, allowing for custom lubrication schemes. |
SD160AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The angular contact design and stainless steel construction enable the bearing to support high radial dynamic load ratings of 3856 lbf and exceptional axial static load ratings of 10130 lbf, providing stable and rigid support for rotating components.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control on the bore diameter and outside diameter, ensuring smooth operation and precise rotational accuracy.
- Optimized for Performance: The brass cage ensures reliable ball guidance, contributing to smooth operation at moderate speeds. The specified radial internal clearance is optimized for the intended operating conditions.
- Corrosion Resistance & Durability: The all-stainless steel construction, including rings and balls, provides excellent resistance to corrosion, making it suitable for harsh environments and applications requiring cleanliness.
SD160AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbals, rotor heads, and precision control mechanisms.
