SF090XP0 Bearing Product Overview & Core Advantages
The SF090XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding compact cross-sections and high precision, this single-row bearing is uniquely designed to simultaneously support combined radial and axial loads from any direction. Its stainless steel construction provides excellent corrosion resistance, making it ideal for harsh environments and high-reliability applications where space and weight are critical constraints.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SF | Indicates the Reali-Slim® thin-section bearing series. |
| 090 | Specifies the bore diameter of 9 inches. |
| XP | Denotes a Four Point Contact ball bearing design. |
| 0 | Specifies an open (unsealed) construction. |
SF090XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to handle significant combined radial and axial loads as well as moment loads efficiently in a single, compact unit, simplifying system design.
- Thin-Section & Lightweight: With a consistent cross-section of 0.75", this bearing provides a large diameter in a minimal space, contributing to overall system weight reduction and compactness.
- High-Capacity & Precision: Manufactured to ABEC-1 precision tolerances, it ensures smooth, quiet operation. The brass cage provides stability at moderate speeds and reliable ball guidance.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls ensures long service life in corrosive or wash-down environments, and the bearing is pre-lubricated for immediate operation.
- High Load Ratings: Engineered for demanding applications, it offers a high axial static load rating of 27,510 lbf and a dynamic load moment rating of 25,410 lbf.
SF090XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a large bore and a slim profile. Key industries and equipment include:
- Robotics: Joint and actuator bearings in robotic arms.
- Aerospace & Defense: Gimbals, radar platforms, and control surfaces.
- Medical Equipment: Imaging scanners (CT, MRI) and surgical robots.
- Semiconductor Manufacturing: Wafer handling and precision positioning stages.
- Machine Tool: Rotary tables and indexing heads.
