SD090XP0 Bearing Product Overview & Core Advantages
The SD090XP0 is a premium Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding high precision and compact design, this single-row bearing excels at simultaneously handling combined radial loads and axial loads from any direction. Its stainless steel construction provides excellent corrosion resistance, making it ideal for challenging environments where reliability is paramount. The combination of a thin cross-section and robust load capacity makes it a superior choice for space-constrained, high-performance systems.
SD090XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SD090XP0 | Series & Size Designation | Identifies the Reali-Slim series with 9" bore and specific performance profile. |
| Open | Seal Type | No contact seals, enabling higher speeds and allowing for custom lubrication schemes. |
| Four Point Contact | Load Direction Capability | Enables the bearing to support substantial axial loads in both directions as well as radial loads and moment loads. |
| ABEC-1 | Tolerance Class | Specifies standard precision tolerances for reliable performance in general industrial applications. |
SD090XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry allows a single bearing to accommodate combined loads (radial, axial, and moment) efficiently, simplifying system design and reducing the need for multiple bearing arrangements.
Thin-Section Construction: With a consistent 0.5" width across large diameters (9" bore, 10" OD), this bearing provides maximum load capacity within a minimal envelope, enabling lightweight and compact machinery.
All-Stainless-Steel Construction: Both rings and balls are manufactured from stainless steel, offering superior corrosion resistance and suitability for clean or harsh environments, including food processing and medical applications.
High Load Capacity: Engineered for demanding applications, it features a high axial static load rating of 16,250 lbf and a significant static load moment of 30,870 lbf, ensuring long-term durability.
Precision Brass Cage: The brass cage ensures stable ball guidance and reliable operation, contributing to smooth running and extended service life.
SD090XP0 Bearing Typical Application Areas
- Robotics and Automation: Robot joints, rotary actuators, and precision positioning stages.
