61912-2RS1/W64 Bearing Product Overview & Core Advantages
The 61912-2RS1/W64 is a single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers reliable operation and long service life. Its key advantages include superior radial load capacity (3709 lbf dynamic rating), integrated Solid Oil lubrication for maintenance-free operation, and sealed construction that protects against contamination. The bearing's optimized design ensures smooth operation across a wide temperature range from -30°C to 120°C, making it suitable for various industrial applications requiring consistent performance.
Model Code Detailed Explanation
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 61912 | Basic designation for single row deep groove ball bearing with 60mm bore, 85mm OD | Standardized sizing for easy replacement and selection |
| 2RS1 | Double contact seals on both sides | Enhanced contamination protection and lubricant retention |
| W64 | Solid Oil lubrication system | Maintenance-free operation, no relubrication required |
61912-2RS1/W64 Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway and precision-ground chrome steel components provide excellent radial load capacity while maintaining compact dimensions (13mm width). The bearing's construction ensures smooth rotation and minimal vibration.
Advanced Sealing Technology: The double contact seals (2RS1) create an effective barrier against contaminants while retaining lubricant. This design significantly extends bearing service life in demanding environments.
Solid Oil Lubrication System: The W64 Solid Oil technology replaces traditional grease with a polymer-based oil-saturated matrix. This provides consistent lubrication throughout the bearing's service life, eliminates lubricant leakage, and enables operation in various orientations without performance degradation.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial internal clearance, this bearing delivers consistent performance and reliable operation in general industrial applications.
