SF040XP0 Bearing Product Overview & Core Advantages
The SF040XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications requiring compact cross-sections and high load capacity, this single row bearing is designed to simultaneously support significant radial loads, axial loads in both directions, and load moments. Its stainless steel construction provides excellent corrosion resistance, making it ideal for demanding environments where reliability and precision are paramount.
SF040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF | Series prefix for Reali-Slim thin section bearings. |
| 040 | Indicates a bore diameter of 4 inches. |
| X | Denotes the cross-section size (0.75" width). |
| P0 | Specifies an open (unsealed) design and standard ABEC-1 precision tolerance class. |
SF040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to handle combined radial loads, bidirectional axial loads, and tilting moments efficiently, replacing the need for more complex bearing arrangements and saving space.
- High Load Capacity: Engineered for substantial dynamic and static load ratings (Radial Dynamic: 4665 lbf, Axial Static: 13400 lbf), ensuring reliable performance under heavy combined loads.
- Thin Section & Lightweight: With a compact cross-section (Width: 0.75") and a weight of only 1.9 lbs, it enables the design of lighter, more compact machinery without sacrificing strength.
- Corrosion-Resistant Materials: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering superior resistance to corrosion and suitability for a wide temperature range (-30°C to 110°C).
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance, ensuring smooth operation and high positional accuracy.
SF040XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robot arms, and precision stages where compact design and high moment load capacity are critical.
- Aerospace and Defense: Gimbals, radar platforms, and control surface actuators benefiting from lightweight and corrosion-resistant properties.
- Medical Equipment: CT scanners, surgical robots, and imaging devices requiring high precision and reliability.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning tables.
- Optical and Instrumentation Systems: Rotary stages and positioning devices where minimal deflection and high accuracy are required.
