Cylindrical Roller Bearings
Product catalog summary
Overview: The document provides detailed specifications and performance characteristics of the NACHI EG Series high capacity cylindrical roller bearings. These bearings are designed to offer enhanced load capacity, reliability, and operational efficiency.
Specifications: The EG Series bearings feature larger roller diameters and increased length to maximize load capacity while maintaining standard boundary dimensions. The bearings are available in various types, including NU, NJ, and NUP, with specific dimensions and load ratings provided in tabular form.
Design and Performance: The EG Series incorporates NACHI's EXCEL CROWNING technology, optimizing internal geometry for improved contact between rollers and raceways under different loading conditions. This design contributes to higher reliability and allows for more compact bearing arrangements.
Noise and Heat Management: The use of a glass-reinforced nylon cage in the EG Series reduces noise and heat generation, particularly in grease-lubricated applications. This design ensures lower temperature operation compared to conventional pressed steel cages.
Testing and Results: The document includes test results comparing the service life and temperature rise of the NU307EG (nylon cage) and NU307 (pressed steel cage) bearings. The EG Series demonstrates a longer service life and lower temperature rise under specified test conditions, including a rotating speed of 2000 min-1 and a radial load of 19600 N.
Key Data: Tables provide detailed dimensions, dynamic and static load ratings, and speed ratings for various bearing models. The document notes that speed ratings should be adjusted for bearings with pressed steel cages by multiplying by 0.8.
Conclusion: The NACHI EG Series cylindrical roller bearings offer significant advantages in load capacity, reliability, and operational efficiency, making them suitable for applications requiring high performance and compact design.
