SD200XP0 Bearing Product Overview & Core Advantages
The SD200XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel series. Engineered for applications requiring compact cross-sections and high load capacity, this bearing excels in handling combined radial and axial loads simultaneously. Its stainless steel construction provides excellent corrosion resistance, making it ideal for demanding environments where reliability and precision are paramount. The bearing is pre-lubricated for immediate use and features an open design for easy re-lubrication or custom sealing solutions.
SD200XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD200 | Reali-Slim series with 20" bore diameter and specific cross-section |
| XP0 | Open construction (no seals), Four Point Contact design |
SD200XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Enables the bearing to support significant combined loads (radial, axial, and moment loads) in a single, compact unit, reducing system complexity and weight.
- Thin Section Construction: With a consistent 0.5" width and minimal cross-section, it saves space in compact machinery designs without sacrificing performance.
- High Load Capacity: Delivers exceptional dynamic and static load ratings (Radial Dynamic: 5534 lbf, Axial Dynamic: 9670 lbf) for its size, ensuring long service life under heavy loads.
- Stainless Steel & Brass Construction: Provides superior corrosion resistance and durability. The brass cage ensures smooth operation and is suitable for a wide temperature range (-30°C to 110°C).
- ABEC-1 Precision: Offers reliable running accuracy for general precision applications, contributing to consistent system performance.
SD200XP0 Bearing Typical Application Areas
- Robotics: Joint and actuator bearings in robotic arms and precision automation systems.
- Aerospace: Control mechanisms, actuation systems, and instrumentation where weight savings and reliability are critical.
- Medical Equipment: Scanning devices, surgical robots, and precision positioning tables.
- Semiconductor Manufacturing: Wafer handling robots and precision stages requiring high rigidity and clean operation.
- Military & Defense Systems: Turret drives, radar positioning systems, and guidance mechanisms.
