SC180XP0 Bearing Product Overview & Core Advantages
The SC180XP0 is a Four Point Contact Thin Section Bearing from the Reali-Slim Stainless Steel series, designed in inch measurements for applications demanding high precision and compact design. As a single row ball bearing, its unique four-point contact geometry enables it to simultaneously support significant combined loads, including radial, axial, and moment loads, in a minimal cross-section. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable performance in demanding environments. Its ABEC-1 precision class and optimized internal clearance ensure smooth, precise operation, making it an ideal choice for space-constrained, high-rigidity applications.
SC180XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SC | Indicates the bearing series (e.g., Reali-Slim Stainless Steel). |
| 180 | Specifies the bore diameter in inches (18.0"). |
| X | Denotes a specific cross-section width (0.375" in this case). |
| P | Indicates a Four Point Contact design for combined load capacity. |
| 0 | Specifies the open (unsealed) configuration and standard clearance. |
SC180XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to support substantial radial loads, axial loads in both directions, and high moment loads simultaneously, simplifying system design and reducing component count.
- Ultra-Thin Cross-Section: With a width of only 0.375", this bearing is engineered for compact and lightweight assemblies, maximizing space efficiency without sacrificing performance.
- High Rigidity & Precision: The stainless steel construction and ABEC-1 tolerance class provide high dimensional stability and rotational accuracy, essential for precision motion control.
- Corrosion Resistance & Durability: The use of stainless steel for rings and balls, combined with a brass cage, ensures long service life and reliable operation in harsh or corrosive environments.
- Optimized Load Ratings: Engineered for high static and dynamic load capacity, including a significant Dynamic Load Moment rating of 22 ft-lbf, enabling it to handle complex loading scenarios.
SC180XP0 Bearing Typical Application Areas
- Robotics & Automation: Robotic arms, rotary joints, and precision actuators where space, weight, and moment load capacity are critical.
- Aerospace & Defense: Gimbals, radar systems, and satellite positioning mechanisms requiring high precision and corrosion resistance.
- Medical Equipment: CT scanners, MRI machines, and surgical robots demanding smooth, precise, and reliable rotation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where cleanliness and accuracy are paramount.
- Optical & Instrumentation Systems: Rotary tables, mirror mounts, and precision instrumentation requiring minimal deflection under load.
