SF075XP0 Bearing Product Overview & Core Advantages
The SF075XP0 is a Four Point Contact thin section bearing from the Reali-Slim Stainless Steel series. Engineered with inch system measurements, this single row ball bearing is designed for applications requiring high precision and compact design in a large bore format. Its defining characteristic is the ability to support significant combined loads, including high axial static load ratings up to 23,280 lbf, making it an ideal solution for space-constrained, high-performance machinery.
SF075XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Significance |
|---|---|
| SF075 | Indicates the bearing size series with a 7.5" bore and 9" outside diameter. |
| XP | Denotes the Four Point Contact design, enabling it to handle combined radial and axial loads simultaneously. |
| 0 | Specifies an Open seal type, suitable for clean environments or custom lubrication systems. |
SF075XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to support substantial axial loads in both directions, as well as radial loads and load moments, simplifying assembly and saving space compared to dual bearing setups.
- Reali-Slim Thin Section: With a consistent cross-section of 0.75", this design minimizes weight and bulk while maintaining a large diameter, crucial for robotics, aerospace, and medical equipment.
- Stainless Steel Construction: Both rings and balls are manufactured from stainless steel, providing excellent corrosion resistance and suitability for the specified temperature range of -30°C to 110°C.
- High Load Capacity: Engineered for demanding applications, it offers a high axial static load rating of 23,280 lbf and a static load moment of 38,410 lbf-in.
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with tight bore and OD tolerances, ensuring reliable performance and smooth operation.
SF075XP0 Bearing Typical Application Areas
This bearing is ideally suited for precision applications where large diameters, compact cross-sections, and high moment load capacity are critical. Key industries and equipment include:
- Robotics: Rotary joints and actuators.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: MRI and CT scanner gantries.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation Systems: High-precision rotary tables and positioning devices.
