SD210XP0 Bearing Product Overview & Core Advantages
The SD210XP0 is a Four Point Contact stainless steel thin-section bearing engineered for applications requiring exceptional precision and corrosion resistance. As part of the Reali-Slim series, it delivers a high load capacity within an extremely compact cross-section, making it ideal for space-constrained, high-performance machinery. Its single row design with a brass cage provides excellent stability and smooth operation under combined radial and axial loads.
SD210XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD210XP0 | Series designation for a specific Reali-Slim bearing size and type. |
| Open (Seal Type) | No integral seals, allowing for higher potential speeds and custom lubrication schemes. Requires a clean operating environment. |
| Four Point Contact | The ball raceway geometry is designed to support significant axial loads in both directions as well as radial loads from a single row of balls. |
| Lubricated | The bearing is supplied with a factory-applied lubricant suitable for its specified temperature range. |
SD210XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The Four Point Contact design and stainless steel construction enable the bearing to handle substantial combined loads (radial, axial, and moment loads) with high rigidity, as evidenced by its Dynamic Load Moment rating of 45,826 lbf.
- Corrosion Resistance & Longevity: Manufactured from stainless steel for both rings and balls, this bearing is inherently resistant to corrosion, making it suitable for harsh environments and ensuring long service life.
- Precision & Smooth Operation: Built to ABEC-1 tolerance standards with a brass cage, the SD210XP0 offers precise running accuracy and low vibration, which is critical for precision applications.
- Compact & Lightweight Design: With a slim 0.5" width and a weight of only 4.04 lbs for its large 21" bore diameter, it provides an optimal strength-to-weight ratio for modern, lightweight machinery designs.
SD210XP0 Bearing Typical Application Areas
- Aerospace & Defense: Actuators, control surfaces, and radar positioning systems.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: MRI and CT scanner gantries, robotic surgery arms.
- Robotics & Automation: Robotic joints, rotary tables, and precision gearboxes.
- Optics & Instrumentation: Telescope mounts and high-precision rotary platforms.
