6311/C3VK252 Bearing Product Overview & Core Advantages
The 6311/C3VK252 is a high-performance single row deep groove ball bearing designed for robust industrial applications. Engineered with Chrome Steel components throughout, it delivers exceptional durability and reliable operation under demanding conditions. Its key advantages include a high radial dynamic load rating of 16,096 lbf, making it suitable for applications with significant radial forces. The bearing features an open design for versatile lubrication options and a C3 radial internal clearance, which accommodates thermal expansion in applications with elevated operating temperatures or heavy interference fits, ensuring stable performance and extended service life.
6311/C3VK252 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Standard designation for a single row deep groove ball bearing with a 55 mm bore, 120 mm OD, and 29 mm width. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy press fits, or where reduced friction and heat generation are desired. |
| VK252 | Manufacturer-specific suffix. Typically denotes a specific cage design and material (in this case, a pressed steel cage), optimized for strength and guiding efficiency at the bearing's limiting speed. |
6311/C3VK252 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceways and continuous shoulder design on both rings enable the bearing to handle not only high radial loads but also moderate axial loads in both directions, offering versatile load-carrying capacity.
- Optimized Cage Performance: The pressed steel cage (VK252) ensures secure ball guidance, reduces friction, and contributes to the bearing's high limiting speed of 5,600 rpm, making it suitable for high-speed applications.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class, it provides reliable running accuracy. The C3 clearance provides operational stability in environments with thermal gradients or where shaft and housing fits are tight.
- High-Quality Material: All critical components (rings, balls, cage) are made from Chrome Steel, providing high hardness, wear resistance, and a long operational lifespan.
