608-2Z/WT Bearing Product Overview & Core Advantages
The 608-2Z is a single row deep groove ball bearing designed for reliable performance in a wide range of applications. As a shielded bearing, it offers effective protection against contaminants while maintaining low friction operation. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, compact dimensions for space-constrained designs, and operation across a broad temperature range. Manufactured to ABEC 1 precision standards, it provides a cost-effective solution for applications requiring consistent performance and high reliability.
608-2Z/WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 608 | Standard bearing series designation, indicating a metric deep groove ball bearing with an 8mm bore, 22mm OD, and 7mm width. |
| 2Z | Signifies non-contact shields on both sides. This provides excellent protection against dust and other particulate contaminants while minimizing friction and heat generation, contributing to the bearing's limiting speed of 34,000 rpm. |
608-2Z/WT Bearing Structural Features & Performance Benefits
- Robust Construction & Load Capacity: Built entirely from chrome steel (rings, balls, and cage), this bearing offers high strength and durability. Its single row deep groove raceway geometry is optimized for high radial dynamic load rating (630 lbf) and static load capacity (248 lbf).
- Shielded Design for Contamination Resistance: The 2Z shields act as a physical barrier, protecting the internal components and extending service life in environments where lubrication retention and contamination exclusion are critical.
- Precision & High-Speed Operation: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, it ensures smooth and quiet operation, suitable for applications with demanding limiting speed requirements.
- Maintenance & Compatibility: Supplied without lubrication ("None"), offering flexibility for the user to apply a specific lubricant suited to their application's needs, operating within a temperature range of -30°C to 120°C.
608-2Z/WT Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors: Small motors, fans, and blowers.
- Power Tools: Drills, grinders, and other handheld equipment.
- Office Machinery: Printers, scanners, and copiers.
- Conveyor Systems: Idler rollers and guide pulleys.
- Medical Devices: Small pumps and precision instruments.
- Automotive Auxiliaries: Alternators, water pumps, and HVAC actuators.
