61800-2RS1/W64L Bearing Product Overview & Core Advantages
The 61800-2RS1/W64L is a miniature deep groove ball bearing designed for compact applications requiring high reliability. This sealed single row bearing excels in handling radial loads and is pre-lubricated with Soild Oil for maintenance-free operation. Its metric dimensions (10mm bore, 19mm OD, 5mm width) and ABEC 1 precision make it ideal for space-constrained, high-speed applications up to 48,000 rpm while providing excellent contamination protection.
61800-2RS1/W64L Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2RS1 | Double rubber contact seals on both sides | Superior contamination protection, retains lubrication effectively |
| W64L | Solid Oil lubrication with special additive package | Maintenance-free operation, extended service life, suitable for -30°C to 120°C temperature range |
61800-2RS1/W64L Bearing Structural Features & Performance Benefits
Optimized Sealing System: The double rubber contact seals (2RS1) provide excellent protection against contaminants while maintaining low friction, contributing to the bearing's high limiting speed of 48,000 rpm.
Advanced Lubrication Technology: The Soild Oil formulation (W64L) ensures consistent lubrication throughout the bearing's service life, eliminating the need for re-lubrication and preventing oil leakage in sensitive applications.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with CN radial clearance, this bearing delivers reliable performance with minimal vibration and noise, making it suitable for precision applications.
High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, ensuring dimensional stability and durability under demanding operating conditions.
