SF350XP0 Bearing Product Overview & Core Advantages
The Reali-Slim Stainless Steel Bearings represent a specialized category of thin section bearings engineered for applications requiring compact design and high precision. This single row, four point contact ball bearing is constructed entirely from stainless steel, offering excellent corrosion resistance. Its primary advantage lies in its ability to support significant combined loads—simultaneously handling radial, axial, and moment loads—within an extremely slim cross-section, making it ideal for space-constrained, high-reliability applications.
SF350XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation / Value | Technical Significance |
|---|---|---|
| Bearing Series | Reali-Slim | Indicates a thin-section bearing designed for compact, lightweight assemblies. |
| Seal Type | Open | No integral seals, allowing for higher possible speeds and custom sealing solutions. |
| Load Direction | Four Point Contact | The raceway geometry allows the bearing to support combined radial, axial, and moment loads efficiently in a single row. |
| Tolerance Class | ABEC-1 | A standard precision grade suitable for a wide range of industrial applications. |
| Lubrication | Lubricated | Comes pre-lubricated for immediate operation, reducing initial setup complexity. |
SF350XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: This is the core structural feature. The raceway is designed so each ball contacts the raceway at four points. This unique geometry enables a single row bearing to withstand substantial moment loads and combined loads, effectively replacing more complex and bulky bearing arrangements.
Thin Section & Full Stainless Construction: With a cross-section of only 0.75", this bearing minimizes space and weight without sacrificing performance. The use of stainless steel for both rings and balls provides excellent corrosion resistance, making it suitable for harsh environments and ensuring long-term reliability.
High Load Capacity: Despite its slim profile, the bearing offers impressive dynamic and static load ratings (e.g., Radial Dynamic: 14,100 lbf, Axial Static: 100,900 lbf). The high static load moment rating of 721,200 lbf-in highlights its robustness against overturning forces.
Precision & Stability: Manufactured to ABEC-1 tolerances with a controlled radial internal clearance, this bearing ensures smooth, predictable operation and contributes to the overall accuracy of the system it is integrated into.
SF350XP0 Bearing Typical Application Areas
- Robotics: Ideal for robot joints and actuators where compact size, low weight, and the ability to handle complex loads are critical.
- Aerospace & Defense: Used in gimbals, control mechanisms, and sensor platforms due to its precision, reliability, and corrosion-resistant stainless steel construction.
- Medical Equipment: Suitable for surgical robots, MRI scanners, and other medical devices requiring clean, compact, and precise motion control.
- Semiconductor Manufacturing: Applied in wafer handling robots and precision stages where minimal particle generation and high accuracy are paramount.
- Optical and Instrumentation Systems: Used in rotary tables and positioning systems that demand high stiffness and minimal deflection under load.
