61910/W64 Bearing Product Overview & Core Advantages
The 61910/W64 is a single row deep groove ball bearing designed for high-performance applications demanding reliability and precision. As a metric series bearing, it excels in handling primarily radial loads with a compact cross-section, making it ideal for space-constrained designs. A key differentiator is its integrated Soild Oil lubrication, which provides long-term, maintenance-free operation across a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent performance and is fully compliant with RoHS and REACH directives, ensuring global acceptability.
61910/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 61910 | Basic bearing designation for a single row deep groove ball bearing with a 50mm bore. | Defines the core bearing dimensions and type, ensuring interchangeability. |
| /W64 | Suffix indicating the bearing is pre-lubricated with Soild Oil. | Eliminates the need for re-lubrication, prevents lubricant leakage, and is suitable for high-speed operation up to 12,000 rpm. |
61910/W64 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to support significant radial dynamic load ratings of 3282 lbf, while also accommodating moderate axial loads in both directions.
- High-Speed Capability: The combination of a chrome steel cage, precision-ground chrome steel components, and integrated Soild Oil lubrication enables a high limiting speed of 12,000 rpm, making it a capable high-speed bearing.
- Maintenance-Free Operation: The Soild Oil filler provides a consistent and reliable lubricating film throughout the bearing's service life, eliminating maintenance intervals and preventing contamination.
- Standardized Precision: Conformance to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance guarantees predictable running accuracy and smooth operation for a wide range of industrial applications.
