SG045AR0 Bearing Product Overview & Core Advantages
The SG045AR0 is a Reali-Slim Stainless Steel Angular Contact Ball Bearing designed for applications requiring exceptional precision and corrosion resistance. This single row bearing features a 30° contact angle, enabling it to support significant combined loads—both radial and axial. Manufactured to ABEC-1 precision standards with a thin cross-section (1" width), it offers a compact, high-performance solution for space-constrained, high-rigidity systems. The use of stainless steel for rings and balls ensures excellent durability in demanding environments.

| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim series of thin-section bearings. |
| 045 | Specifies the bore diameter of 4.5 inches. |
| A | Denotes the 30° contact angle, optimized for handling combined loads. |
| R | Signifies the use of stainless steel construction for enhanced corrosion resistance. |
| 0 | Indicates an open (unsealed) design, suitable for controlled environments or custom lubrication systems. |
SG045AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides high rigidity and is engineered to support substantial radial dynamic load ratings (6562 lbf) and axial static load ratings (14530 lbf), making it ideal for applications with combined loads.
- Precision Performance: Manufactured to ABEC-1 tolerance classes with a tight radial internal clearance (0.0000 – 0.0005 inches), this bearing ensures smooth operation, reduced vibration, and high positional accuracy.
- Corrosion Resistance & Durability: The stainless steel rings and balls, combined with a brass cage, offer excellent resistance to corrosion and wear, extending service life in harsh conditions.
- Space-Saving Design: As part of the Reali-Slim series, it features a thin cross-section (1" width relative to its 4.5" bore), enabling compact and lightweight assemblies without sacrificing performance.
SG045AR0 Bearing Typical Application Areas
- Aerospace & Defense: Actuators, control systems, and radar platforms where precision, corrosion resistance, and high load capacity are critical.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices requiring sterile-compatible materials and reliable performance.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that demand ABEC-1 precision and minimal particle generation.
- Food & Beverage Processing: Machinery in wash-down environments benefiting from stainless steel construction and corrosion resistance.
- Robotics & Automation: Rotary joints, servo motors, and articulated arms where thin-section bearings enable compact, high-rigidity designs.
