| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2RS1 | Double Contact Seals (Rubber) | Provides excellent protection against contaminants and moisture ingress |
| W64 | Solid Oil Lubrication | Ensures maintenance-free operation, prevents lubricant leakage, and extends service life |
61811-2RS1/W64 Bearing Structural Features & Performance Benefits
Compact Design & High Rigidity: The single row deep groove construction with 9 mm width provides excellent radial stiffness while maintaining minimal cross-section, ideal for space-constrained applications.
Enhanced Sealing Performance: The double rubber contact seals (2RS1) effectively exclude contaminants while retaining lubrication, significantly increasing bearing service life in harsh environments.
Maintenance-Free Operation: The Solid Oil lubrication (W64) eliminates the need for relubrication, prevents oil leakage, and maintains consistent performance across the entire operating temperature range.
Optimized Load Capacity: With a radial dynamic load rating of 2032 lbf and static load rating of 1978 lbf, this bearing delivers reliable performance under substantial radial loads.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance standards with CN clearance, ensuring smooth operation and consistent performance in precision applications.
