SB120XP0 Bearing Product Overview & Core Advantages
The SB120XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding extreme thin cross-sections without compromising load capacity, this bearing excels in compact, space-constrained designs. Its four point contact design enables it to simultaneously support significant radial loads, axial loads in both directions, and moment loads, making it an ideal, all-in-one solution for complex loading scenarios. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation.
SB120XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB120 | Product series designation for a 12" bore Reali-Slim bearing. |
| XP0 | Indicates an open (unsealed) design and standard ABEC-1 precision tolerance. |
SB120XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact & High Load Capacity: The unique raceway geometry creates four distinct contact points between the balls and raceways. This design allows the SB120XP0 to handle combined radial, bidirectional axial, and moment loads efficiently, with high static load moment (30,770 lbf-in) and dynamic load moment (9,446 lbf-in) ratings.
- Ultra-Thin Section & Space Savings: With a cross-section of only 0.3125", this bearing provides a large 12" bore relative to its 12.625" outside diameter, maximizing structural space within lightweight and compact assemblies.
- Corrosion-Resistant Construction: Both the rings and balls are made from stainless steel, offering superior performance in harsh environments where corrosion is a concern. The brass cage ensures smooth operation and durability.
- Precision & Reliability: Manufactured to ABEC-1 tolerance standards, this bearing guarantees consistent performance and smooth running for a wide range of industrial applications.
SB120XP0 Bearing Typical Application Areas
- Robotics: Rotary joints, robotic arms, and manipulators requiring high moment load capacity in a thin section.
- Aerospace & Defense: Radar platforms, gimbal systems, and satellite positioning mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robots where precision and corrosion resistance are critical.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Machine Tool: Rotary tables and indexing heads for light to medium-duty applications.
