The NB SLIDE GUIDE is a high-precision and high-rigidity linear guide designed to utilize the motion of rolling elements. They have numerous advantageous characteristics including low friction, no stick/slip, and smooth linear motion even under high load conditions. Since they can maintain their high-efficiency and high-functionality characteristics for an extended period of time, they meet a wide range of needs, from general industrial to precision machinery.

  • The NB SLIDE GUIDE SEB type is a profile miniature linear rail guide system in which the ball elements roll along two raceway grooves. This is the smallest and lightest slide guide series offered by Nippon Bearing. The compact design allows for the size and weight of machinery and other equipment to be reduced.

  • EXRAIL® - A new innovative linear recirculating linear guide rail system to achieve ultra-high rigidity, ultra-high motion accuracy, and ultra-high damping capability. Incorporation of needle rollers gives the EXRAIL® 50% higher rigidity and higher damping capability compared to current roller bearing and guide way assemblies in the market. Nippon Bearing incorporated the latest technology including a built in lubricated porous resin material to meet customer expectations for extended lubrication intervals, three oil holes for flexibility in lubrication options and side seals, under seals, and inner seals for advanced dust prevention capabilities. The EXRAIL®’s seals are made from HNBR, a special material known for oil and ozone proof properties and strong wear resistance. The EXRAIL® is a linear recirculating roller bearing and guide way assembly whose carriage and guide way are supplied as pre-assembled units. This allows the EXRAIL® to perform at its maximum capability for high precision and rigidity.
