61815/C3 Bearing Product Overview & Core Advantages
The 61815/C3 is a metric single row deep groove ball bearing engineered for high-performance applications demanding reliability and precision. Its open design and C3 radial internal clearance make it exceptionally suited for operational conditions involving thermal expansion or where interference fits are utilized. This bearing excels in handling pure radial loads and offers a high limiting speed, making it a robust and versatile component for power transmission systems requiring consistent performance under demanding conditions.
61815/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 61815 | Standard series designation for a single row deep groove ball bearing with a 75mm bore. | Indicates the basic bearing type and size. |
| /C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Essential for applications with shaft or housing interference fits, or where operational temperatures cause differential expansion, preventing premature failure. |
61815/C3 Bearing Structural Features & Performance Benefits
The performance of the 61815/C3 is a direct result of its design and material selection:
- Optimized Load Capacity: The single row deep groove construction is fundamentally designed to support high radial dynamic and static load ratings, providing reliable service life.
- High-Speed Capability: Manufactured from high-grade chrome steel for both rings and balls, and featuring a chrome steel cage, this bearing is built for stability and durability at its high limiting speed of 8,500 rpm.
- Precision & Stability: Produced to ABEC 1 | ISO P0 tolerance class, it ensures consistent running accuracy and low vibration, which is critical for smooth operation.
- Operational Flexibility: The open seal type allows for versatile lubrication regimes, while the C3 clearance provides the necessary operational flexibility for challenging thermal and fit conditions.
61815/C3 Bearing Typical Application Areas
The 61815/C3 bearing is a preferred choice in a wide array of industrial machinery where reliability under radial load and high speed is paramount. Key applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
