6209 TN9W/C4H Bearing Product Overview & Core Advantages
The 6209 is a single row deep groove ball bearing designed for outstanding performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers reliable operation due to its robust construction. Its key advantages include a high limiting speed of 7,700 rpm and a generous radial internal clearance of C4, making it exceptionally suitable for applications involving thermal expansion or where shaft misalignment is a concern. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution without compromising on essential precision and reliability.
6209 TN9W/C4H Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6209 | Basic Bearing Number | Indicates a single row deep groove ball bearing with a 45mm bore, 85mm OD, and 19mm width. |
| - | No Standard Suffix | Confirms the bearing is an open (unsealed) design. |
| C4 | Radial Internal Clearance | Specifies a greater than normal internal clearance, ideal for applications with significant temperature gradients or misalignment. |
6209 TN9W/C4H Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Built from chrome steel for both rings and balls, this bearing delivers high strength and durability. Its single row deep groove raceway is optimized to support substantial radial dynamic load ratings of 7351 lbf and static load ratings of 4564 lbf.
High-Speed Capability with Nylon Cage: The lightweight and durable nylon cage ensures smooth operation at high rotational speeds, contributing to the bearing's impressive limiting speed. This design minimizes friction and heat generation.
Flexibility with C4 Clearance: The specified C4 radial internal clearance provides operational flexibility. It accommodates shaft expansion under high-temperature conditions and can tolerate minor misalignments, reducing stress and extending service life.
Open Design for Custom Lubrication: As an open bearing supplied without lubrication, it offers the flexibility to be paired with a specific grease or oil best suited for the application's unique speed, temperature, and environmental conditions.
