SC042AR0 Bearing Product Overview & Core Advantages
The SC042AR0 is a thin section angular contact ball bearing designed for applications requiring high precision and space optimization. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is engineered to support combined loads, handling significant axial loads in one direction alongside radial loads. Its Reali-Slim design provides a large bore diameter relative to its cross-section, making it ideal for compact, weight-sensitive assemblies. The bearing comes pre-lubricated and is rated for a temperature range of -30°C to 110°C, ensuring reliable performance in various operating conditions.

| SC | Stainless Steel, Angular Contact configuration |
| 042 | Bore diameter code for 4.25 inches |
| A | 30° contact angle design |
| R0 | Radial internal clearance designation (0.0000 – 0.0005") |
SC042AR0 Bearing Structural Features & Performance Benefits
This bearing's performance stems from its specialized construction:
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides excellent rigidity and enables the bearing to support high axial static loads (2880 lbf) and radial dynamic loads (1194 lbf).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight bore diameter and outside diameter tolerances, ensuring smooth operation and precise rotational accuracy.
- Corrosion Resistance & Longevity: The stainless steel rings and balls, combined with a brass cage, offer superior corrosion resistance, making it suitable for harsh environments and enhancing service life.
- Space-Saving Design: The thin section bearing construction (0.375" width) allows for significant weight reduction (0.46 lbs) and compact assembly designs without sacrificing performance.
SC042AR0 Bearing Typical Application Areas
The SC042AR0 is ideally suited for precision applications where space, weight, and corrosion resistance are critical factors. Key industries and equipment include:
- Robotics and Automation: Joint actuators, rotary tables, and precision gearboxes.
- Aerospace & Defense: Guidance systems, radar platforms, and optical instrument gimbals.
- Medical Equipment: Surgical robots, imaging scanners, and laboratory automation.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages.
