The zero-backlash preload results in an extremely low displacement resistance
Major components are made of stainless steel
Type NDN micro frictionless table consists of four major components: the stainless steel top and bottom parts, the brass cage, and the stainless roller elements. The U-shaped cage connects the two rows of balls so the tendency towards cage creep is largely eliminated. The NDN micro frictionless tables are preloaded with zero backlash and the displacement resistance is extremely low. Type NDN is available in a single-axis version in three sizes.
