SD180XP0 Bearing Product Overview & Core Advantages
The SD180XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding high load capacity and compact design, this single-row bearing is uniquely capable of simultaneously supporting significant radial loads, axial loads in both directions, and load moments. Its stainless steel construction provides excellent corrosion resistance, making it ideal for precision machinery operating in challenging environments where reliability and a slim cross-section are paramount.
SD180XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD180 | Indicates the series (Reali-Slim) and the bore diameter of 18 inches. |
| X | Denotes a Four Point Contact design, enabling the bearing to handle combined loads. |
| P0 | Specifies the precision class, corresponding to ABEC-1 tolerance. |
| Open (from spec) | Signifies an unsealed (Open) construction, suitable for systems with external lubrication. |
SD180XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to support radial loads, bidirectional axial loads, and tilting moments simultaneously, effectively replacing complex bearing arrangements and simplifying system design.
- High Load Capacity: Engineered for substantial dynamic and static load ratings (e.g., Radial Static: 12,650 lbf, Axial Static: 31,640 lbf), ensuring durability under heavy combined loads.
- Stainless Steel Construction: Both rings and balls are made from stainless steel, offering superior corrosion resistance and suitability for a wide operating temperature range (-30°C to 110°C).
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a minimal radial internal clearance (0.0000 – 0.0005"), providing consistent running accuracy and high rigidity for precise positioning.
- Compact & Lightweight: With a slim cross-section (Width: 0.5") and a weight of only 3.48 lbs, it enables space-saving and weight-critical designs without compromising performance.
SD180XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a large diameter, thin-section bearing with high moment load capacity. Key industries and equipment include:
- Robotics: Rotary joints and manipulator arms.
- Aerospace & Defense: Radar platforms, gimbal systems, and satellite mechanisms.
- Machine Tool: Rotary tables, indexers, and CNC positioning systems.
- Medical Equipment: CT scanners and MRI systems.
- Semiconductor Manufacturing: Precision wafer handling and positioning stages.
