Sealed four-row conical roller bearing "CROU-LL type"

Achieved a 9% increase in load capacity compared to conventional NTN products, doubled load-bearing capacity, and reduced internal water ingress by 50%!

The "CROU-LL type" is a sealed four-row tapered roller bearing from the ULTAGE series, designed to achieve "high load capacity," "high load resistance," and "high sealing performance" required for steel roll neck applications. By maximizing the dimensions and number of rollers, it realizes high load capacity and extended lifespan. A new type of crowning has been adopted for the rolling elements, significantly improving load-bearing performance by equalizing the contact stress distribution between the rolling elements and the raceway. A "high sealing type" fluororubber seal with a reduced seal volume is standard. By optimizing the main lip's tension and incorporating an external foreign object shielding structure, it cuts internal water ingress by over 50% while preventing grease leakage with the secondary lip. 【Features】 ■ World-class high load capacity design ■ World-class load-bearing performance ■ Compact high-sealing design ■ Long-life grease as standard ■ 1.3 times the rated lifespan compared to our conventional products *For more details, please download the PDF or feel free to contact us.
