608-2ZTN9/C5MT33 Bearing Product Overview & Core Advantages
The 608-2ZTN9/C5MT33 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing features a compact design with a shielded construction, offering robust protection against contamination. Its primary advantages include the ability to handle significant radial loads and operate effectively at high rotational speeds. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and is an ideal choice for applications requiring a balance of precision, durability, and cost-effectiveness.
608-2ZTN9/C5MT33 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 608 | Standard series designation for a deep groove ball bearing with 8mm bore. | Defines the basic bearing dimensions and type. |
| 2Z | Bearing is shielded on both sides. | Provides effective contamination protection, retaining lubrication and extending service life. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced, snap-type design. | Contributes to quiet operation, low friction, and suitability for high-speed applications. |
| C5 | Radial internal clearance greater than normal (C0). | Accommodates thermal expansion in applications with higher operating temperatures or where fits result in clearance reduction. |
| MT33 | High-performance, lithium soap-based grease. | Ensures optimal lubrication for the specified temperature range (-30° to 120 °C), offering long-term, maintenance-free operation. |
608-2ZTN9/C5MT33 Bearing Structural Features & Performance Benefits
Optimized Load Handling: The single row deep groove raceway geometry is designed to support high radial dynamic load ratings (630 lbf), making it robust for various mechanical loads.
High-Speed Capability: The combination of the lightweight TN9 nylon cage and effective MT33 grease lubrication allows the bearing to achieve a high limiting speed of 34,000 rpm, minimizing friction and heat generation.
Enhanced Service Life & Reliability: The double-shielded (2Z) design effectively seals the bearing, protecting the chrome steel components and grease from contaminants. This, combined with the pre-lubrication, results in a maintenance-free and long-lasting bearing solution.
Precision & Stability: Manufactured to ABEC 1 precision class with strict dimensional tolerances, this bearing provides reliable and consistent running accuracy, which is critical for smooth operation.
608-2ZTN9/C5MT33 Bearing Typical Application Areas
