SA075AR0 Bearing Product Overview & Core Advantages
The Reali-Slim Stainless Steel Bearings series represents a specialized category of thin section bearings engineered for applications demanding compact design and corrosion resistance. This single row angular contact ball bearing with a 7.5" bore is designed to handle significant combined loads, efficiently supporting both radial and axial forces. Its stainless steel construction ensures excellent corrosion resistance, making it ideal for harsh environments. The compact cross-section (0.25" width) provides a high load capacity relative to its size, offering a robust solution for space-constrained, high-precision machinery requiring high rigidity and reliable performance.

SA075AR0 Bearing Structural Features & Performance Benefits
The performance of this bearing is defined by its specific structural characteristics. The 30° contact angle is crucial for its ability to support high axial static loads (2190 lbf), making it an excellent choice for applications with significant thrust forces. The use of a brass cage ensures stable operation and reliable guidance of the stainless steel balls. Despite its slim 0.25" width, the bearing maintains a high radial static load rating of 2720 lbf and a static load moment of 7840 lbf, demonstrating exceptional load carrying capacity for its cross-section. The tight radial internal clearance (0.0000 – 0.0005") contributes to precise shaft guidance and smooth running. The stainless steel rings and balls provide inherent corrosion resistance, extending service life in challenging conditions.
SA075AR0 Bearing Typical Application Areas
This thin section angular contact bearing is ideally suited for applications where space is at a premium and corrosion resistance is mandatory. Key industries and equipment include:
- Robotics and Automation Equipment (for joint and arm articulation)
- Aerospace Actuation Systems and Control Surfaces
- Medical Equipment such as MRI scanners and surgical robots
- Semiconductor Manufacturing Equipment
- Precision Rotary Tables and Indexing Heads
- Food Processing and Packaging Machinery (where washdowns are common)
