As a metric bearing with an open design, it is optimized for radial load handling while also accommodating moderate axial loads. Its construction from high-grade Chrome Steel ensures durability and reliable operation. The bearing features a CN radial internal clearance and ABEC-1 precision class, making it a robust and cost-effective solution for a wide range of machinery requiring consistent performance and long service life.
6411 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6411 | Standard designation for a single row deep groove ball bearing with a 55mm bore, 140mm OD, and 33mm width. |
| Open (Seal Type) | No integral seals or shields, allowing for higher speeds and custom lubrication schemes. Requires external sealing in contaminated environments. |
| ABEC-1 | Standard precision tolerance class, suitable for most general industrial applications. |
| CN | Normal radial internal clearance group, standard for most operating conditions. |
6411 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 22,368 lbf and a static load rating of 13,938 lbf, the 6411 bearing is designed to handle significant radial loads, ensuring reliable operation under strenuous conditions.
- Optimized for High-Speed Operation: The stainless steel cage provides strength and stability, contributing to a high limiting speed of 5,000 rpm. The open design reduces friction and heat generation.
- Precision and Consistency: Manufactured to ABEC-1 tolerances, this bearing offers precise running accuracy, which is critical for reducing vibration and noise in rotating assemblies.
- Durable Material Construction: The rings and balls made from Chrome Steel provide high hardness and wear resistance, while the stainless steel cage offers excellent corrosion resistance.
