6208-2Z Bearing Product Overview & Core Advantages
The 6208-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing offers high precision and reliability. Its key advantage lies in its ability to accommodate high radial loads while operating efficiently at high speeds. The integrated shielded design (2Z) and factory-applied grease lubrication provide robust contamination protection and long-term, maintenance-free operation, making it an ideal solution for compact and high-reliability machinery.
6208-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6208 | Basic Bearing Series & Size | Denotes a standard 6200 series deep groove ball bearing with a 40mm bore, 80mm OD, and 18mm width. |
| 2Z | Seal/Shield Type | Indicates the bearing is shielded on both sides with metal shields. This provides effective protection against solid contaminants while allowing for high-speed operation. |
6208-2Z Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is precision-engineered to support high radial dynamic load ratings (7306 lbf) and radial static load ratings (4271 lbf), ensuring durability under significant stress.
High-Speed Capability: Featuring a stainless steel cage and optimized internal design, this bearing achieves a limiting speed of 9,000 rpm, making it suitable for high-rotation applications.
Precision & Rigidity: Manufactured to a P6 tolerance class with tight dimensional control on the bore diameter and outside diameter, this bearing provides precise running accuracy and enhanced system rigidity.
Maintenance-Free Operation: The combination of Z-shields on both sides and pre-filled grease lubrication seals in the lubricant and seals out contaminants, enabling long service intervals and reduced maintenance costs.
Material Integrity: Constructed from chrome steel for rings and balls, the bearing offers high wear resistance and a broad operating temperature range from -30°C to 120°C.
