308 NR/C3VE110 Bearing Product Overview & Core Advantages
The 308 NR/C3 is a single row deep groove ball bearing engineered for high-performance radial load applications. Its defining feature is the integral snap ring on the outer ring, which provides secure axial location and simplifies housing design by eliminating the need for complex shoulder machining. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, this bearing offers reliable operation under a wide range of conditions, including thermal expansion. The open design allows for versatile lubrication options, making it a robust and cost-effective solution for demanding industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 308 | Basic Bearing Series & Size | Standard metric dimension series (40mm bore, 90mm OD). |
| NR | Snap Ring (fitted) | Outer ring has a groove and is supplied with a snap ring for axial location. |
| C3 | Radial Internal Clearance | Greater than normal clearance, suitable for applications with thermal expansion or interference fits. |
308 NR/C3VE110 Bearing Structural Features & Performance Benefits
Deep Groove Raceway & High-Capacity Design: The optimized raceway geometry enables the bearing to handle significant radial dynamic loads (10,274 lbf) and radial static loads (8,093 lbf), making it exceptionally durable.
Snap Ring for Simplified Assembly: The integrated snap ring (outer ring locating feature) allows for a simplified and more economical housing design, reducing machining costs and assembly time while ensuring secure axial positioning.
Optimized for Versatility & High-Speed Operation: With a limiting speed of 8,500 rpm and an open seal type, this bearing is highly adaptable. It can be paired with various lubrication systems to achieve optimal performance in high-speed applications.
Robust Material Construction: All critical components—rings, balls, and cage—are manufactured from high-grade chrome steel, ensuring consistent performance, long service life, and high resistance to wear.
308 NR/C3VE110 Bearing Typical Application Areas
- Electric Motors & Gearboxes: Ideal for locating bearings in compact motor designs.
- Industrial Pumps & Compressors: Handles radial loads and simplifies housing construction.
