SC045AR0 Bearing Product Overview & Core Advantages
The SC045AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and accuracy. As part of the Reali-Slim Stainless Steel Bearings series, it features a single row design optimized to handle significant combined loads, including radial and axial loads in one direction. Its compact cross-section and 30° contact angle make it ideal for space-constrained, high-reliability systems demanding precise rotational motion and long service life.

SC045AR0 Bearing Structural Features & Performance Benefits
Superior Rigidity & Load Capacity: The angular contact design with a 30° contact angle provides excellent resistance to combined radial and axial loads, delivering high static load moment capacity (8270 lbf).
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore and OD tolerance: -0.0008" to 0"), ensuring smooth operation and precise positioning.
Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent corrosion resistance and suitability for harsh environments.
Space-Saving Design: The thin section bearing configuration (0.375" width) maximizes performance in minimal space, ideal for compact machinery designs.
SC045AR0 Bearing Typical Application Areas
- Robotics & Automation: Robot arm joints, precision gearing systems
- Aerospace & Defense: Guidance systems, actuator mechanisms
- Medical Equipment: Surgical robots, diagnostic imaging devices
