Technical Advantages
- Enhanced Load Capacity: The "XL" (Extra Load) design incorporates additional rollers compared to standard bearings, delivering significantly higher radial load ratings and shock resistance capabilities.
- Superior Durability: X-LIFE technology optimizes internal geometry, surface finishes, and material quality, extending service life by up to 50% compared to conventional bearings.
- Thermal Flexibility: The NU design permits axial movement of up to 0.2–0.5 mm, accommodating thermal expansion in high-temperature environments, while the C3 clearance prevents seizure under thermal stress.
- Efficient Operation: The TVP2 polyamide cage minimizes friction, reduces operating temperatures, and enables higher rotational speeds than full-complement bearings, improving energy efficiency.
- Easy Maintenance: Separable inner ring facilitates straightforward mounting/dismounting, inspection, and relubrication, reducing downtime and maintenance costs.
Performance Ratings
- Dynamic Load Rating (C): 53 kN
- Static Load Rating (C₀): 63 kN
- Limiting Speed: Up to 8,500 rpm (depending on lubrication and operating conditions)
Ideal Applications
The FAG NU208-E-XL-TVP2-C3 excels in diverse industrial sectors, particularly:
- Gearboxes: Transmission systems requiring high radial loads and thermal expansion accommodation
- Electric Motors: High-efficiency motors for industrial drives, pumps, and compressors
- Pumps & Compressors: Rotating equipment handling variable loads and speeds
- Agricultural Machinery: Heavy-duty farm equipment operating in harsh conditions
- Material Handling: Conveyor systems, gear reducers, and industrial fans
- Textile Machinery: High-speed looms and spinning equipment requiring precision and reliability
Mounting & Usage Recommendations
- Suitable for use as a support bearing; can be combined with HJ angle rings (sold separately) to accommodate light axial loads in one direction
- Recommended operating temperature range: -30°C to +120°C (with appropriate lubrication)
- Preferable lubrication: Grease (mineral or synthetic) with a base oil viscosity of 10–100 mm²/s at operating temperature
- Mounting should be performed using proper tools to avoid damage to bearing surfaces or cage
