608-ZTN9/C5MT33 Bearing Product Overview & Core Advantages
The 608-ZTN9/C5MT33 is a single row deep groove ball bearing designed for precision applications requiring high reliability. This metric bearing excels in handling primarily radial loads and offers smooth operation. Its compact design, featuring an 8 mm bore and 22 mm outside diameter, makes it ideal for space-constrained assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and is pre-lubricated with high-performance grease for immediate use, offering a broad operating temperature range from -30° to 120 °C.
608-ZTN9/C5MT33 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 608 | Standard series designation for a deep groove ball bearing with an 8mm bore. | Defines the basic size and type of the ball bearing. |
| Z | Shield on one side. | Provides effective protection against contamination from one side while maintaining low friction. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced. | Contributes to light weight, low friction, and excellent performance at high speeds, supporting the limiting speed of 34,000 rpm. |
| C5 | Radial internal clearance greater than Normal (CN). | Suited for applications where thermal expansion is a concern, ensuring stable operation under varying temperature conditions. |
| MT33 | High-performance lithium soap base grease. | Provides long-term lubrication, wide temperature range capability, and contributes to the bearing's maintenance-free characteristics. |
608-ZTN9/C5MT33 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is designed for efficient radial load distribution, minimizing stress concentrations and ensuring smooth rotation.
High-Speed Nylon Cage (TN9): The glass fiber reinforced polyamide cage is lightweight and possesses excellent sliding properties, which is critical for achieving the high limiting speed of 34,000 rpm. It reduces centrifugal forces and ensures stable cage guidance.
Shielded Protection: The pressed steel shield (Z-type) effectively retains the MT33 grease and protects the bearing interior from larger particulate contaminants, enhancing service life in various environments.
Precision & Material Integrity: Manufactured from chrome steel for both rings and balls, this bearing offers high hardness and wear resistance. Adherence to ABEC 1 | ISO P0 tolerance class guarantees dimensional accuracy and running precision.
