NJ300 series

The NJ300 series is engineered for high-load and high-rigidity scenarios. It features a larger outer diameter than the NJ200 series with a comparable width, enabling the use of more and larger rollers. This structural enhancement, combined with an expanded contact ellipse, fundamentally boosts load capacity and shaft support rigidity. The trade-off for this robustness is a slightly lower speed capability due to the increased mass.
