E2.6301-2Z/C3 Bearing Product Overview & Core Advantages
The E2.6301-2Z/C3 is a single row deep groove ball bearing engineered for reliable performance in demanding applications. This precision bearing features a shielded design for contaminant protection and is characterized by its C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its robust construction from chrome steel ensures high durability and the ability to handle significant radial dynamic loads up to 2271 lbf, offering a compact and efficient solution for various industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| E2.6301 | Basic bearing designation, indicating a single row deep groove ball bearing with a 12 mm bore, 37 mm OD, and 12 mm width. |
| 2Z | Signifies the bearing is shielded on both sides. This provides effective protection against solid contaminants while allowing for high-speed operation. |
| C3 | Indicates a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, heavy interference fits, or where lower operating temperatures are expected. |
E2.6301-2Z/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength and wear resistance. Its single row deep groove geometry is optimized to support high radial dynamic load ratings, ensuring long service life under demanding conditions.
- Contaminant Protection with Shields (2Z): The non-contact steel shields on both sides effectively prevent the ingress of large particulate contaminants, protecting the internal components and preserving lubricant integrity. This design contributes to maintenance-free operation in many environments.
- Optimized Internal Clearance (C3): The C3 clearance group provides extra operational space within the bearing. This feature is essential for compensating for dimensional changes due to heat or press-fits, preventing premature failure from excessive preload and ensuring smooth, reliable performance.
- Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, it offers reliable running accuracy for a wide range of applications. The shielded design and precision grinding contribute to a high limiting speed of 22,000 rpm.
