SD180AR0 Bearing Product Overview & Core Advantages
The SD180AR0 is a high-precision thin section bearing engineered for applications demanding compact design and superior performance. As a single row angular contact ball bearing, it is specifically designed to handle combined loads, efficiently supporting significant radial loads and axial loads in one direction. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and durability. Its ABEC-1 precision class and optimized 30° contact angle ensure smooth, reliable operation in high-accuracy systems, making it an ideal solution for space-constrained, high-performance machinery.
SD180AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD | Indicates the bearing series, specifically Reali-Slim Stainless Steel Bearings. |
| 180 | Specifies the bore diameter of 18 inches. |
| A | Denotes the 30° contact angle, optimized for handling high axial loads. |
| R | Signifies the use of a brass (Riveted) cage for stability and strength. |
| 0 | Indicates an open (unsealed) construction, suitable for systems with external lubrication. |
SD180AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design: With a cross-section of only 0.5", this bearing provides a maximum load capacity within a minimal space envelope, enabling lightweight and compact machinery design.
- High Load Capacity: The 30° contact angle and robust stainless steel construction enable it to handle high combined loads, with a dynamic radial load rating of 4113 lbf and a static moment load capacity of 42,180 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance, it ensures smooth, low-vibration operation essential for high-precision applications.
- Corrosion Resistance & Durability: The all-stainless steel components (rings and balls) and brass cage offer excellent resistance to corrosion and are suitable for a wide operating temperature range from -30°C to 110°C.
SD180AR0 Bearing Typical Application Areas
The SD180AR0 is ideally suited for demanding applications across various industries, including:
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning stages.
