SF160AR0 Bearing Product Overview & Core Advantages
The SF160AR0 is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance in inch dimensions. This single row bearing features a 30° contact angle, optimized to handle combined loads—significant radial loads alongside high thrust loads in one direction. Manufactured entirely from Stainless Steel with a Brass cage, it offers superior corrosion resistance and reliable operation. Its Reali-Slim thin-section construction provides a high load capacity within a compact, space-saving cross-section, making it ideal for high-precision and high-reliability machinery where size and weight are critical constraints.
SF160AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF | Indicates the product series: Reali-Slim Stainless Steel Bearings. |
| 160 | Specifies the bore diameter in inches, which is 16.000". |
| A | Denotes the contact angle of 30°, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (C0). |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for custom lubrication schemes and maximum speed capability. |
SF160AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The 30° contact angle and robust stainless steel construction enable the bearing to support high radial dynamic load ratings of 7563 lbf and exceptional axial static load ratings of 19,540 lbf, providing stable and rigid support for shafts under complex loading conditions.
- Precision & Speed: Built to ABEC-1 precision tolerances with a tight radial internal clearance (0.0000" – 0.0005"), this bearing ensures smooth, quiet operation and is suitable for high-speed applications. The brass cage contributes to operational stability and durability at elevated speeds.
- Corrosion Resistance & Lightweight: The all-stainless steel components, including rings and balls, provide excellent resistance to corrosion, making it suitable for harsh environments. The thin-section design minimizes weight (6.78 lbs) and rotational inertia without compromising strength.
- Wide Temperature Range: The bearing is lubricated and capable of operating within a temperature range of -30°C to 110°C, ensuring performance across various industrial conditions.
SF160AR0 Bearing Typical Application Areas
This bearing is engineered for applications where precision, corrosion resistance, and high load capacity in a compact form factor are paramount. Key industries and equipment include:
- Aerospace & Defense: Gimbal systems, rotor heads, and precision instrumentation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: MRI scanners, surgical robots, and high-speed centrifuges.
- Robotics: Robot arm joints and precision actuators.
- Food & Beverage Processing: Machinery requiring frequent washdowns and corrosion resistance.
