SB180XP0 Bearing Product Overview & Core Advantages
The SB180XP0 is a Four Point Contact thin section bearing from the Reali-Slim Stainless Steel series, designed for applications demanding high precision and space-saving solutions. This single row ball bearing is engineered to simultaneously support combined loads, including significant radial, axial, and moment loads, within an extremely compact cross-section. Its stainless steel construction provides excellent corrosion resistance, making it ideal for challenging environments. The bearing is pre-lubricated for immediate use, offering reliable performance and long service life.
SB180XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB180 | Base model number indicating the specific thin-section bearing size (18" bore). |
| X | Denotes the Four Point Contact design, enabling it to handle combined radial, axial, and moment loads. |
| P0 | Specifies an Open (unsealed) construction, allowing for custom lubrication schemes or operation in clean environments. |
SB180XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to support substantial axial loads from both directions and high moment loads efficiently, simplifying assembly and reducing the need for complex bearing arrangements.
- Thin Section & High Rigidity: With a remarkably slim cross-section (0.3125" width on an 18" bore), it maximizes space utilization while the stainless steel construction and precise geometry provide excellent structural rigidity and dimensional stability.
- Superior Load Capacity: Engineered for high static and dynamic load ratings, including a Radial Static Load Rating of 7440 lbf and a significant Static Load Moment of 68090 lbf, ensuring reliable performance under demanding conditions.
- Precision & Corrosion Resistance: Manufactured to ABEC-1 tolerance standards with Stainless Steel rings and balls and a Brass cage, it delivers smooth operation, low torque, and resistance to corrosion.
- Pre-lubricated for Immediate Use: Comes lubricated from the factory, reducing initial setup time and ensuring optimal performance within its specified temperature range of -30°C to 110°C.
SB180XP0 Bearing Typical Application Areas
- Robotics and Automation: Ideal for robot joints, rotary actuators, and precision gearing systems where compact design and high moment load capacity are critical.
- Aerospace and Defense: Used in radar platforms, satellite communication systems, and flight control mechanisms requiring lightweight, corrosion-resistant components.
- Medical Equipment: Suitable for MRI scanners, surgical robots, and diagnostic imaging devices demanding high precision and reliability.
- Semiconductor Manufacturing: Applied in wafer handling robots, precision stages, and other cleanroom equipment where contamination control is essential.
- Optical and Instrumentation Systems: Perfect for rotary tables, positioning stages, and telescope mounts requiring smooth, precise motion control.
