SG055XP0 Bearing Product Overview & Core Advantages
The SG055XP0 is a premium Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding high precision and compact design, this bearing excels at simultaneously handling combined radial and axial loads from any direction. Its thin-section construction provides maximum load capacity within minimal cross-sectional space, making it ideal for weight-sensitive and space-constrained applications requiring high rigidity and reliable performance.
SG055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SG | Reali-Slim Series | Ultra-thin cross-section for space optimization |
| 055 | Bore Diameter: 5.5 inches | Large bore for shaft mounting compatibility |
| XP | Extra Precision (ABEC-1) | Enhanced running accuracy and smooth operation |
| 0 | Open Seal | Maximum speed capability and easy relubrication |
SG055XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support combined radial and axial loads in any direction with a single bearing row, providing exceptional load moment capacity (21 ft-lbf rated load moment).
Stainless Steel Construction: Both rings and balls are manufactured from stainless steel, offering excellent corrosion resistance and suitability for harsh environments, with an operating temperature range of -30°C to 110°C.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0010"– 0"), ensuring precise fit and smooth operation in high-precision applications.
High Load Capacity: The optimized design delivers outstanding dynamic and static load ratings (radial dynamic: 8979 lbf, axial dynamic: 13180 lbf) despite the thin-section profile, providing reliable performance under demanding conditions.
