SG160AR0 Bearing Product Overview & Core Advantages
The SG160AR0 is a high-precision thin section angular contact ball bearing engineered for applications demanding exceptional rigidity and accuracy within compact spaces. Manufactured from corrosion-resistant stainless steel, this single-row bearing is specifically designed to handle significant combined loads, supporting substantial radial and axial forces simultaneously due to its defined 30° contact angle. Its ABEC-1 precision grade ensures reliable performance in high-accuracy positioning systems, making it an ideal solution for precision applications where space and weight are critical constraints.
SG160AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the bearing series: Reali-Slim® Thin Section Stainless Steel Bearings. |
| 160 | Specifies the nominal bore diameter in sixteenths of an inch (16/16" = 1" Bore). |
| A | Denotes the contact angle of 30°, optimized for carrying high axial loads. |
| R0 | Specifies the radial internal clearance group (C0). |
| Open | No seals or shields, allowing for custom lubrication schemes and high-speed operation. |
SG160AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row design with a 30° contact angle and stainless steel construction provides high rigidity, enabling the bearing to support high combined loads (Radial Dynamic: 12,142 lbf, Axial Static: 30,830 lbf).
- Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0016" to 0"), ensuring smooth operation and accurate rotational performance in precision applications.
- Corrosion Resistance & Durability: Both rings and balls are made from stainless steel, offering excellent corrosion resistance for use in harsh environments, while the brass cage ensures stable operation.
- Space-Saving Design: As a thin section bearing (1" width with 16" bore), it provides a large diameter-to-cross-section ratio, maximizing performance in compact, weight-sensitive designs.
SG160AR0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Precision Robotics: Rotary joints and arm assemblies requiring high moment load capacity (Static Load Moment: 93,020 lbf-in).
- Aerospace & Defense Systems: Gimbals, radar platforms, and control surfaces where corrosion resistance and reliability are critical.
- Medical Equipment: CT scanners and surgical robot arms demanding high precision and smooth motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages operating in cleanroom environments.
- Industrial Automation: Rotary tables and indexing units where high axial stiffness and accuracy are required.
