EE 3 TN9 Bearing Product Overview & Core Advantages
The EE 3 TN9 is a single row deep groove ball bearing designed for exceptional precision and reliability in demanding applications. Manufactured to P6 tolerance class, this bearing offers superior running accuracy and is optimized for handling significant radial loads. Its compact inch design (0.375" bore) makes it ideal for applications where space is limited but performance cannot be compromised. The combination of chrome steel rings, a lightweight Nylon cage, and a specified CN radial internal clearance ensures smooth operation and high-speed capability up to 43,000 rpm.
EE 3 TN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| EE 3 | Indicates the specific bearing series and size in the inch system. |
| TN9 | Specifies the use of a glass-fiber reinforced Nylon 66 cage. This cage design contributes to low friction, quiet operation, and is suitable for high-speed applications. |
Note: This is an Open (unsealed) bearing with None pre-applied lubrication, offering maximum flexibility for custom lubrication schemes.
EE 3 TN9 Bearing Structural Features & Performance Benefits
- High Precision & Speed: Built to P6 tolerance standards with a Nylon TN9 cage, this bearing achieves excellent rotational accuracy and a high limiting speed of 43,000 rpm, making it a true high-speed bearing.
- Robust Load Capacity: With a dynamic load rating of 746 lbf and a static load rating of 315 lbf, it provides reliable performance under substantial radial loads.
- Optimal Material Selection: The use of chrome steel for both rings and balls ensures high durability and resistance to wear, supporting long service life.
- Wide Temperature Range: Operates effectively in a temperature range from -30°C to 120°C, accommodating various environmental conditions.
