Innovation Raises Linear Guides Standards
The EXRAIL® linear guide has more rollers in less space than other linear bearings, which increases load capacity and disperses the load more evenly. It has longer rollers for greater contact surface and less contact pressure.
By using needle rollers, the EXRAIL® slide guide provides smoother movement. Its multiple small diameter needle rollers reduce dynamic frictional resistance and range of fluctuation of dynamic frictional resistance.
Another EXRAIL® feature is that its Static Load Capacity is higher. In fact, for the new design independent testing data indicated that it exhibited higher performance than presently available products. The EXRAIL® had a 1.5 to 2 times higher static load rating as well as allowable static moment in the rolling, pitching, and yawing directions in comparison to other products on the market.
Since 1939, NB has been the leading manufacturer of high-quality linear motion products in Japan due to our unique product designs, attention to detail and fresh approaches to meeting linear motion needs.
NB Linear Systems are linear motion mechanisms using the recirculating movement of ball or roller elements to provide smooth and accurate linear travel. Products are designed to minimize size and weight while providing superior performance in high-precision equipment. The products are low friction and low noise. They’re available as total systems or as individual components.
