Product Overview:
The NUP 2213 EM C3 RICH is a heavy-duty single row cylindrical roller bearing engineered for maximum radial load capacity and high-speed stability. As a NUP-type bearing, it features two integral flanges on the outer ring and one fixed flange plus a loose flange ring on the inner ring, allowing for axial displacement of the shaft in both directions while providing precise location. This model is built with a reinforced "E" execution and a premium machined brass cage, which offers superior durability and heat resistance compared to standard steel or polyamide cages. The C3 internal clearance ensures the bearing operates efficiently under high thermal loads, preventing seizure caused by shaft expansion in demanding industrial gearboxes and electric motors.
Key Performance Advantages:
- High Radial Load Capacity: Reinforced execution (E) provides a larger roller set for intense industrial forces.
- Machined Brass Cage: Offers excellent frictional properties and strength for high-vibration or high-speed applications.
- NUP Design Flexibility: Facilitates axial location of the shaft while simplifying mounting and dismounting procedures.
- C3 Clearance Optimization: Designed for heavy-duty cycles where thermal expansion is a critical operational factor.
Transparency Note: This bearing is manufactured under the RICH brand. The code NUP 2213 EM C3 is used solely for identification and does not imply affiliation with other manufacturers.
