NB Anti Cage-Creep Cross Roller Slide Guides and Tables

This NB STUDROLLER™ crossed-roller linear bearing is perfect for motion control applications with extremely fast acceleration and deceleration (at dimensions ranging from 30-600mm lengths, 1-12 mm rollers, endurance is 150 million cycles), NB’s new NV type crossed roller bearing's Anti-Creep Cage Technology guarantees zero slippage.

NB, by placing studs in the center roller and machining a correspondingly dimpled path in the rail, has produced a retainer that never slips. (Patent Pending)

In addition load capacities are increased 1.4 to 2.3 times over the standard SV type. Roller-to-rail contact area is extended 42 to 58 percent while the number of rollers is increased 20 to 55 percent. STUDROLLER™, lowers component costs and allows more compact designs.

In all stainless steel, the NB STUDROLLER™ is ideal for use in special environments that are highly corrosive, high temperature or vacuums.

    00:00:02 with the conventional products the roller slip phenomenon caused by repetitive motion of the track base creates deviant in the retainer causing a problem in handling high-speed specification or vertical axis specification through use of a novel idea and high technical strength to overcome this problem the new stud roller NV type which completely

    00:00:27 eliminates roller slip has been created [Music] the neone bearing slideway MV type and the mvt type each consist of a resin R retainer with a built-in stud roller and a track base precisely ground for the stud roller to move smoothly this stud roller system based on our new idea has completely eliminated slip inside the product

    00:00:54 enabling use in any position and handling of super high accelerated and decelerated motions further the optimal design of the roller transfer part and the resin R retainer have improved the sliding feature sound is quieter and movement is smoother than the ball circulation type guide and assured use is now possible also for motion under micro Strokes

    00:01:22 which has been a problem in the [Music] past furthermore the new track based design increased the length of contact between the roller and the transfer Surface by 42 to 58% in addition by making the roller pitch smaller and increasing the number of effective rollers by 20 to 55% the rated load increased 1.4 to 2.3
