SF300XP0 Bearing Product Overview & Core Advantages
The SF300XP0 is a Four Point Contact thin section bearing engineered for applications demanding high precision and compact design. Manufactured from stainless steel with a brass cage, this single-row ball bearing is designed to simultaneously handle significant combined loads, including radial, axial, and moment loads. Its Reali-Slim cross-section provides a high load capacity within a minimal space envelope, making it ideal for weight-sensitive and high-reliability applications. The bearing comes pre-lubricated and is rated for a wide operating temperature range.
SF300XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF300XP0 | Specific manufacturer model designation for this thin section, four-point contact bearing series. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for maximum speed and easy re-lubrication in clean environments. |
| Lubricated | The bearing is pre-lubricated from the factory, ensuring immediate operation and initial corrosion protection. |
SF300XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to support combined radial, axial, and moment loads simultaneously in a single bearing row, simplifying assembly and saving space.
- High Load Capacity: Engineered to handle a high Dynamic Load Moment of 150,708 lbf and a Static Load Moment of 533,600 lbf, providing robust performance in demanding applications.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with tight dimensional control on the bore, outside diameter, and width for precise running accuracy and system rigidity.
- Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent resistance to corrosion and making it suitable for harsh environments.
- Compact & Lightweight: The Reali-Slim thin-section design minimizes weight and cross-sectional space while maintaining high performance, contributing to overall system efficiency.
SF300XP0 Bearing Typical Application Areas
- Robotics: Ideal for robot joints and arms where compact size, moment load capacity, and precision are critical.
- Aerospace & Defense: Used in gimbal systems, radar platforms, and flight control mechanisms due to its precision and reliability.
- Medical Equipment: Suitable for MRI scanners, surgical robots, and other medical devices requiring corrosion-resistant, non-magnetic components.
- Semiconductor Manufacturing: Applied in precision stages and wafer handling equipment where high accuracy and clean operation are paramount.
- Optical & Instrumentation Systems: Used in rotary tables and positioning systems that demand minimal friction and high rotational accuracy.
