SD065AR0 Bearing Product Overview & Core Advantages
The SD065AR0 is a high-precision thin section bearing engineered for applications demanding space optimization without compromising performance. As a single row angular contact ball bearing manufactured from stainless steel, it is designed to handle significant combined loads, particularly excelling in managing thrust loads from one direction due to its specific contact angle. Its Reali-Slim cross-section provides a compact, lightweight solution ideal for high-accuracy and high-reliability systems where weight and space are critical constraints.
SD065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD | Indicates the bearing series, specifically the Reali-Slim Stainless Steel line. |
| 065 | Specifies the bore diameter in inches (6.5"). |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the internal clearance group (Radial Internal Clearance: 0.0000 – 0.0005"). |
SD065AR0 Bearing Structural Features & Performance Benefits
Superior Material Construction: The use of stainless steel for rings and balls, combined with a brass cage, provides excellent corrosion resistance and durability in harsh environments, aligning with ROHS compliance.
High Load Capacity & Rigidity: The single row angular contact design and 30° contact angle enable the bearing to support high radial dynamic load ratings (2346 lbf) and exceptional axial static load ratings (5720 lbf), making it highly rigid under combined loading conditions.
Precision & Speed: Manufactured to ABEC-1 tolerance standards with a tightly controlled radial internal clearance, this bearing ensures smooth operation and is suitable for applications requiring precise rotational accuracy.
Space-Saving Design: As a thin section bearing with a cross-section of only 0.5" in width, it offers a significant reduction in weight and envelope size, contributing to overall system efficiency.
SD065AR0 Bearing Typical Application Areas
- Robotics and Automation: Ideal for robotic arms, joints, and rotary tables where compactness, precision, and load capacity are paramount.
- Aerospace and Defense: Used in gimbal systems, control mechanisms, and radar antennas due to its lightweight stainless steel construction.
- Medical Equipment: Suitable for imaging devices (CT/MRI scanners) and surgical robots requiring high hygiene standards and reliable performance.
- Semiconductor Manufacturing: Applied in precision stages and wafer handling equipment where minimal deflection and high accuracy are critical.
- Optical and Instrumentation Systems: Used in rotary encoders, telescopes, and precision measuring devices demanding smooth, low-friction motion.
