SG070AR0 Bearing Product Overview & Core Advantages
The SG070AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and load capacity. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is specifically designed to handle significant combined loads, accommodating both radial forces and substantial thrust loads in one direction. Its Reali-Slim cross-section provides a compact, space-saving design ideal for sophisticated machinery where weight and size are critical constraints. The bearing is pre-lubricated for immediate operation and offers reliable performance across a wide temperature range from -30°C to 110°C.
SG070AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the bearing series: Reali-Slim thin section stainless steel bearings. |
| 070 | Specifies the nominal bore diameter in inches: 7 inches. |
| A | Denotes the contact angle of 30°, optimized for handling high axial loads. |
| R0 | Specifies the internal clearance group and likely denotes an open (unsealed) construction. |
SG070AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity and enables the bearing to support substantial combined radial and axial loads. It features impressive ratings including a radial dynamic load capacity of 8035 lbf and a high axial static load capacity of 18650 lbf.
- Precision & Stability: Manufactured to ABEC-1 precision tolerances with a controlled radial internal clearance (0.0000" – 0.0005"), ensuring smooth, precise operation and minimal runout for high-accuracy applications.
- Corrosion Resistance & Longevity: Constructed entirely from stainless steel (rings and balls), the bearing offers excellent corrosion resistance, making it suitable for harsh environments and ensuring a long service life.
- Space-Efficient Design: As part of the Reali-Slim series, it provides a large bore diameter relative to its cross-section (1" width), enabling compact and lightweight assembly designs.
SG070AR0 Bearing Typical Application Areas
The SG070AR0 is ideally suited for high-precision machinery and systems where load capacity, compact design, and corrosion resistance are paramount. Key industries and equipment include:
- Robotics: Robotic arms and rotary joints.
- Aerospace & Defense: Radar platforms, gimbal systems, and control surface actuators.
- Medical Equipment: High-precision scanners, surgical robots, and imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical Instrumentation: Rotary tables and positioning systems.
