608-2RZTN9/C3VT162F6 Bearing Product Overview & Core Advantages
The 608-2RZTN9/C3VT162F6 is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation and compact design. This sealed bearing excels in handling significant radial loads and is engineered for smooth, high-speed operation. Its construction ensures high reliability in demanding environments, making it an ideal choice for applications where precision and durability are paramount. The bearing is pre-lubricated and features a C3 radial internal clearance, which accommodates thermal expansion in high-speed or high-temperature scenarios.
608-2RZTN9/C3VT162F6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 608 | Standard series designation for a deep groove ball bearing with 8mm bore, 22mm OD, and 7mm width. |
| 2RZ | Indicates non-contact seals on both sides, providing effective protection against contaminants while minimizing friction. |
| TN9 | Specifies a glass fiber reinforced nylon cage (Polyamide 66), contributing to low weight, quiet operation, and high-speed capability. |
| C3 | Denotes a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| VT162F6 | Identifies the specific high-performance grease lubrication (compatible with the specified temperature range of -30°C to 120°C). |
608-2RZTN9/C3VT162F6 Bearing Structural Features & Performance Benefits
- High-Speed Performance: The combination of the lightweight TN9 nylon cage and optimized grease lubrication (VT162F6) enables a high limiting speed of 34,000 rpm, making it an excellent high-speed bearing solution.
- Robust Sealing & Contamination Resistance: The 2RZ non-contact seals on both sides effectively shield the internal components from dust, moisture, and other contaminants, significantly extending service life and enabling maintenance-free operation in many applications.
- Optimized Internal Clearance: The C3 radial internal clearance provides operational stability in applications subject to thermal gradients or interference fits, preventing binding and ensuring smooth rotation.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings and balls, this bearing delivers consistent performance and high durability under radial dynamic loads up to 630 lbf.
608-2RZTN9/C3VT162F6 Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized motors requiring high-speed operation and long-term reliability.
- Power Tools: Used in drills, grinders, and other handheld tools where compact size and high RPM are critical.
- Office Machinery & Computer Peripherals: Commonly found in cooling fans, printer rollers, and spindle drives.
- Medical Equipment: Suitable for low-noise, high-speed devices such as dental handpieces and small pumps.
- Automotive Auxiliary Systems: Applied in components like idler pulleys, alternators, and small blower motors.
