61908-2RS1/W64 Bearing Product Overview & Core Advantages
The 61908-2RS1/W64 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and sealed operation. Its compact design, featuring a 40mm bore, 62mm outside diameter, and 12mm width, delivers exceptional space efficiency. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent precision and smooth operation. The integrated Solid Oil lubrication and sealing system provides long-term, maintenance-free service across a wide temperature range from -30°C to 120°C, making it an ideal solution for applications demanding high reliability and durability.
61908-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides superior protection against contaminants and retains lubrication effectively. |
| /W64 | Solid Oil lubrication | Ensures consistent lubrication, eliminates leakage, and enables maintenance-free operation. |
61908-2RS1/W64 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its optimized construction. The single row deep groove geometry is designed to handle significant radial loads (dynamic rating: 3102 lbf) while accommodating moderate axial loads in both directions. The use of high-grade chrome steel for all bearing components (rings, balls, cage) ensures high strength and extended service life. The CN radial internal clearance is the standard for normal operating conditions, providing a balance between smooth running and load capacity. The combination of contact seals (2RS1) and Solid Oil (W64) creates a robust, sealed-for-life unit, capable of operating at limiting speeds up to 14,000 rpm without relubrication, significantly reducing total cost of ownership.
61908-2RS1/W64 Bearing Typical Application Areas
The 61908-2RS1/W64 is specified in a wide range of industries and equipment where reliability and minimal maintenance are critical. Common applications include:
- Electric Motors and small generators
- Industrial gearboxes and transmission systems
- Pumps, fans, and blowers
- Material handling equipment (conveyors, pulleys)
- Agricultural machinery
- Automotive auxiliary units
