608-ZRZTN9/VK250 Bearing Product Overview & Core Advantages
The 608-ZRZTN9/VK250 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. This precision bearing is distinguished by its asymmetric sealing configuration, featuring one side shielded and one side sealed, offering a balanced solution for contamination protection and low running torque. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and is capable of handling significant radial loads, making it an ideal component for applications requiring compact design and dependable operation.
608-ZRZTN9/VK250 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| Z | One Side Shielded (Metal Shield) | Protects from large particulate contaminants on one side. |
| RZ | One Side Sealed (Low-Friction Contact Seal) | Provides superior sealing against fine dust and moisture with minimal impact on speed. |
| TN9 | Nylon Cage (Polyamide Cage), Glass Fiber Reinforced | Enables quieter operation, lower friction, and is suitable for higher speeds. |
| VK250 | Specific High-Performance Grease | Optimized for the bearing's operational temperature range and speed, providing long-term lubrication. |
608-ZRZTN9/VK250 Bearing Structural Features & Performance Benefits
The design of the 608-ZRZTN9/VK250 incorporates several key features that translate directly into performance benefits. The deep groove raceway and single row construction are optimized for high radial dynamic load rating (630 lbf). The combination of a Z shield and an RZ contact seal offers a robust defense against contaminants while maintaining a high limiting speed of 34,000 rpm. The TN9 nylon cage contributes to the high-speed capability, reduces weight, and ensures smooth operation. The bearing is pre-lubricated with VK250 grease, making it ready for immediate use and reducing maintenance needs across its wide temperature range of -30°C to 120°C.
