SC040AR0 Bearing Product Overview & Core Advantages
The SC040AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability in a compact envelope. As part of the Reali-Slim Stainless Steel Bearings series, it is designed to handle significant combined loads, supporting both radial and axial forces simultaneously due to its 30° contact angle. Its ABEC-1 precision class and corrosion-resistant stainless steel construction make it an ideal choice for high-accuracy systems where space and weight are critical constraints.
SC040AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Indicates the bearing is part of the Stainless Steel, Reali-Slim series. |
| 040 | Specifies the bore diameter of 4 inches. |
| A | Denotes the 30° contact angle, optimized for handling combined loads. |
| R | Signifies Brass retainer (cage) material for enhanced strength and durability. |
| 0 | Indicates an Open (unsealed) design, suitable for controlled environments or custom lubrication systems. |
SC040AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and brass cage, provides excellent rigidity and enables the bearing to support high radial dynamic load ratings (1153 lbf) and axial static load ratings (2770 lbf).
- Precision & Accuracy: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise operation and minimal runout in high-accuracy applications.
- Corrosion Resistance & Lightweight: Constructed entirely from stainless steel (rings and balls), the bearing offers superior corrosion resistance. Its thin-section design results in a low weight of only 0.44 lbs, critical for reducing system inertia.
- Wide Temperature Range: The standard lubrication and stainless steel construction allow for reliable operation across a temperature range of -30°C to 110°C.
SC040AR0 Bearing Typical Application Areas
- Robotics & Automation: Gantry systems, rotary joints, and robotic arms where precision motion and compact design are paramount.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms requiring lightweight and corrosion-resistant components.
- Medical Equipment: Imaging devices (CT/MRI scanners) and surgical robots demanding high precision and reliability.
- Semiconductor Manufacturing: Wafer handling and precision stages where ABEC-1 precision and cleanroom compatibility are essential.
