SF120XP0 Bearing Product Overview & Core Advantages
The SF120XP0 is a high-performance **Four Point Contact** ball bearing engineered for demanding thin-section applications. This **stainless steel bearing** delivers exceptional load capacity in a compact design with a 12" bore and 0.75" cross-section. Its **single row construction** is optimized to simultaneously handle significant **radial loads** and **axial loads** from both directions, making it an ideal solution for applications requiring high rigidity and precision within a minimal envelope. Manufactured to **ABEC-1** tolerance standards, it offers reliable performance and long service life.
SF120XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF120 | Denotes the Reali-Slim series with a 12" bore diameter. |
| XP | Indicates a Four Point Contact ball bearing design. |
| 0 | Specifies an open (unsealed) construction. |
SF120XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry allows a single row bearing to support combined radial and axial loads efficiently, simplifying assembly and reducing the need for complex bearing arrangements.
- High Load Capacity: Engineered with a Dynamic Load Moment of 38 ft-lbf and a Static Load Moment of 91730 lbf, it provides robust performance under high moment loads.
- Precision & Rigidity: Manufactured to ABEC-1 precision tolerances with a controlled radial internal clearance, ensuring smooth operation and accurate positioning.
- Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with a brass cage, making it suitable for applications exposed to moisture or corrosive environments.
- Pre-lubricated: Comes lubricated from the factory for immediate use, operating effectively within a temperature range of -30°C to 110°C.
SF120XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space and weight are critical constraints, including:
- Robotics and Automation (Robotic arms, rotary joints)
- Aerospace & Defense (Gimbals, radar platforms)
- Medical Equipment (CT scanners, rotating assemblies)
- Semiconductor Manufacturing (Wafer handling robots)
- Precision Rotary Tables and Indexers
