608/W64 Bearing Product Overview & Core Advantages
The 608 is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered to primarily handle radial loads, its open design and high-quality construction ensure reliable operation. A key advantage is its Solid Oil lubrication, which provides long-term, maintenance-free service across a wide temperature range from -30°C to 120°C. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a cost-effective solution for applications requiring consistent precision and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 608 | Standard designation for a metric series, single row deep groove ball bearing with an 8mm bore, 22mm OD, and 7mm width. |
| Open | No physical contact seals or shields, allowing for higher limiting speeds and easier relubrication if required. |
| Solid Oil | The bearing is pre-filled with a polymer matrix saturated with oil, offering superior lubrication retention, contamination resistance, and extended service life. |
| CN | Standard radial internal clearance for normal operating conditions. |
608/W64 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The deep groove raceway and single row design are engineered to efficiently support significant radial dynamic load ratings (630 lbf), making it ideal for applications where radial forces are predominant.
- High-Speed Capability: The open construction and Solid Oil lubrication work in concert to minimize friction and heat generation, enabling a high limiting speed of 34,000 rpm.
- Maintenance-Free Operation: The integrated Solid Oil system eliminates the need for relubrication, reducing maintenance costs and preventing lubrication-related failures. This is particularly beneficial in hard-to-reach or sealed-for-life assemblies.
- Precision and Consistency: Manufactured from Chrome Steel for all critical components (rings, balls, cage) and held to ABEC 1 tolerances, this bearing ensures smooth, quiet, and reliable performance.
608/W64 Bearing Typical Application Areas
This versatile bearing is widely used across various industries, including:
- Electric Motors: Small motors for appliances, power tools, and fans.
- Office Machinery: Printers, scanners, and copiers.
- Material Handling: Conveyor rollers and pulley systems.
- Consumer Products: Skateboards, inline skates, and fishing reels.
- Industrial Drives: Low to medium power transmission systems.
