61914/C3W64E Bearing Product Overview & Core Advantages
The 61914/C3W64E is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and precision operation. Its defining characteristic is the C3 radial internal clearance, optimized for applications with thermal expansion or demanding fit conditions. The integrated Soild Oil lubrication provides long-term, maintenance-free operation across a wide temperature range from -30°C to 120°C. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for general industrial machinery.
61914/C3W64E Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 61914 | Basic Model: Deep Groove Ball Bearing Series | Indicates a standard single row design with a 70mm bore, 100mm OD, and 16mm width. |
| /C3 | Radial Internal Clearance greater than Normal (CN) | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring smooth operation under thermal gradients. |
| W64E | Solid Oil Lubrication System | The bearing is pre-lubricated with a polymer matrix saturated with oil, offering superior contamination resistance and eliminating relubrication needs. |
61914/C3W64E Bearing Structural Features & Performance Benefits
Robust Construction for Radial Loads: The single row deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide excellent dynamic and static load ratings (5350 lbf / 4114 lbf), ensuring durability under continuous operation.
Optimized for Operational Stability: The specified C3 clearance is critical for applications where interference fits or operational heat generation are factors, preventing binding and reducing friction and noise.
Maintenance-Free Longevity: The Soild Oil (W64E) system is a key advantage, providing consistent lubrication without leakage or the risk of being washed out. This makes the bearing ideal for sealed-for-life applications and harsh environments where maintenance access is limited.
Balanced High-Speed Capability: With a limiting speed of 8,500 rpm, this bearing is suitable for a wide range of industrial drives and motors, supported by its precision ABEC 1 grading.
61914/C3W64E Bearing Typical Application Areas
- Electric Motors and Generators: A reliable component in various AC/DC motors requiring maintenance-free operation.
- Industrial Gearboxes and Transmissions: Used in shafts and supports where radial loads and moderate speeds are present.
- Material Handling Equipment: Conveyor rollers, pulleys, and other machinery benefiting from the sealed, long-life lubrication.
- Agricultural Machinery: Implements and drives that operate in dusty or dirty conditions where the Solid Oil system excels.
- General Industrial Machinery: Pumps, fans, and blowers where cost-effective, reliable bearing performance is essential.
