208/C3 Bearing Product Overview & Core Advantages
The 208/C3 is a single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and operational stability. This metric bearing features an open design and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and interchangeability. A key characteristic is its specified C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion, heavy loads, or where interference fits are used, providing enhanced operational reliability and longevity.
208/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 208 | Standard bearing series designation, indicating a 40mm bore, 80mm OD, and 18mm width. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with elevated operational temperatures or heavy load conditions to prevent pre-loading and potential bearing seizure. |
208/C3 Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove construction is fundamentally designed to support high radial dynamic load ratings (7554 lbf), making it a robust choice for a wide array of machinery.
Operational Flexibility with C3 Clearance: The specified C3 clearance provides extra space between the rolling elements and raceways. This design feature accommodates shaft expansion under heat or tight fitting conditions, reducing friction and the risk of premature failure, thereby enhancing bearing service life.
High-Speed Capability: With a limiting speed of 9,500 rpm, this bearing is capable of operating in demanding high-velocity environments common in industrial equipment.
Material Integrity: Constructed entirely from chrome steel for rings, balls, and cage, this bearing offers excellent durability, wear resistance, and consistent performance across its specified temperature range of -30°C to 120°C.
208/C3 Bearing Typical Application Areas
The 208/C3 is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Agricultural Machinery
- Material Handling Conveyors
- Pumps and Fans
Its design is ideal for applications where reliable performance under significant radial loads and potential thermal effects is paramount.
