SA042AR0 Bearing Product Overview & Core Advantages
The SA042AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space-saving designs. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its defining feature is the 30° contact angle, which provides superior axial load capacity in one direction while also handling significant radial loads. This makes it an ideal, compact solution for high-rigidity systems where weight and cross-section are critical constraints.
SA042AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Indicates the Stainless Steel construction of the bearing rings and balls. |
| 04 | Specifies the series, denoting a specific cross-section and bearing size profile. |
| 2 | Represents the contact angle of 30°. |
| A | Signifies the Angular Contact bearing type. |
| R0 | Denotes a specific internal design and radial internal clearance group. |
SA042AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design: With a minimal cross-section of only 0.25", this bearing is fundamental for lightweight and compact machinery, enabling significant space and weight savings without sacrificing performance.
- High Axial Load Capacity: The 30° contact angle is optimized to support high one-directional thrust loads, making it suitable for applications with significant axial forces.
- Corrosion Resistance: The use of stainless steel for rings and balls ensures reliable operation in harsh or washdown environments and contributes to a long service life.
- Precision & Stability: Manufactured to ABEC-1 tolerance standards, it provides consistent running accuracy. The brass cage ensures stable operation and reliable ball guidance.
SA042AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision equipment where a slim profile is essential. Key industries and machinery include:
- Aerospace Actuators and Control Systems
- Robotic Arms and Joints
- Medical and Dental Equipment
