608-ZRZTN9/C3VK272 Bearing Product Overview & Core Advantages
The 608-ZRZTN9/C3VK272 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing features a unique one side shielded, one side sealed configuration, offering superior protection against contamination while retaining lubrication. Its design is optimized to handle significant radial loads and is characterized by its compact dimensions (8mm bore, 22mm OD, 7mm width), making it an ideal choice for applications where space is at a premium and operational reliability is critical.
608-ZRZTN9/C3VK272 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 608 | Standard series designation for a deep groove ball bearing with an 8mm bore diameter. |
| ZR | The bearing has a shield on one side (Z) and a contact seal on the other side (R), providing robust protection. |
| TN9 | Indicates a glass fiber reinforced nylon cage (PA66), which contributes to low weight, quiet operation, and is suitable for high speeds. |
| C3 | Specifies a greater than normal radial internal clearance, ideal for applications with anticipated thermal expansion or where interference fits are used. |
| VK272 | This suffix denotes a specific, high-performance lubricating grease formulation, ensuring optimal performance across the specified temperature range. |
608-ZRZTN9/C3VK272 Bearing Structural Features & Performance Benefits
The performance of the 608-ZRZTN9/C3VK272 is derived from its carefully selected components and design. The single row deep groove raceway is precision-ground from chrome steel for consistent performance and durability. The nylon TN9 cage ensures smooth operation at the high limiting speed of 34,000 rpm, reducing friction and wear. The asymmetric sealing solution (ZR) is a key feature; the sealed side effectively retains the premium VK272 grease and excludes contaminants, while the shielded side offers low-friction protection, contributing to the bearing's long service life and low maintenance requirements. The C3 radial clearance provides operational stability in environments prone to thermal fluctuations.
