608-2RZTN9/C3HGWF Bearing Product Overview & Core Advantages
The 608-2ZTN9/C3 is a single row deep groove ball bearing designed for high reliability in demanding applications. This sealed bearing excels in handling primarily radial loads and offers a compact, lightweight solution. Its key advantages include a high limiting speed and consistent performance across a wide temperature range, making it ideal for applications requiring precision and durability. The combination of a nylon cage and C3 radial internal clearance ensures smooth operation and accommodates thermal expansion.
608-2RZTN9/C3HGWF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 608 | Standard bearing series designation, indicating a metric deep groove ball bearing with an 8mm bore. | Defines the core bearing dimensions and type. |
| 2Z | Contact seal on both sides. | Provides effective protection against contaminant ingress, enhancing bearing life and enabling maintenance-free operation. |
| TN9 | Polyamide (Nylon 66) cage, glass fiber reinforced, snap-type design. | Contributes to low friction, quiet running, and is suitable for high speeds. Offers good strength and guidance. |
| C3 | Radial internal clearance greater than Normal (C0) group. | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring stable operation under varying temperatures. |
608-2RZTN9/C3HGWF Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for both rings and balls, this bearing provides high load capacity and excellent wear resistance. The single row deep groove raceway is optimized for efficient radial load support.
- High-Speed Capability: The lightweight TN9 nylon cage minimizes centrifugal forces, enabling a high limiting speed of 34,000 rpm. This makes it suitable for high-speed applications.
- Sealed & Ready-to-Use: The 2Z contact seals on both sides effectively retain the factory-applied grease and exclude contaminants like dust and moisture. This design offers a long service life without the need for relubrication.
- Precision & Stability: Manufactured to ABEC 1 / ISO P0 tolerance class, it ensures consistent performance and smooth operation. The C3 clearance provides operational stability in applications where fit and thermal conditions may cause a reduction in internal clearance.
608-2RZTN9/C3HGWF Bearing Typical Application Areas
The 608-2ZTN9/C3 is a versatile component widely used in:
- Electric Motors: Small motors, fans, and blowers where high speed and sealed operation are critical.
- Office Automation Equipment: Printers, scanners, and copiers.
- Power Tools: Drills, grinders, and other handheld tools requiring durable, high-speed bearings.
- Medical Devices: Small pumps, dental handpieces, and laboratory equipment.
- Textile Machinery: Spindles and other high-speed rotating parts.
