NTN Products 2. NTN Roller Follower This type of bearing is used in mechanisms where the outer ring rolls on a track, such as aligning rollers, guide rollers, rocker arm rollers, cam rollers, and pressure rollers. For increased durability, it features a thick-walled outer ring capable of withstanding greater loads and impacts. The outer surface of the outer ring (rolling surface) can be ordered in either spherical and cylindrical configurations. 3. Magnetic bearing spindle The NTN magnetic bearing spindle is comprised of two radial magnetic bearings and one thrust magnetic bearing, which support the spindle by magnetic force. All bearings in the five-axis control type spindle have a position sensor to assist the controller in providing the correct amount of force to keep the spindle in a fixed position. 298
NTN Products 4. High precision air spindle This air spindle can be supported without direct contact by feeding clean compressed air between a rotor and a stator to form thin air film . NTNs super precision machining technique enables precision of rotation up to the submicron level. It also features less friction and longer service life. 5. NTN BEAREE FL3305 & FL3307 BEAREE FL3305 & FL3307 are unique sliding materials designed for machine tools. Oil lubrication achieves the smallest friction coefficient possible. These materials have the following features: ¡Minimized friction coefficient (with oil lubrication) ¡Smaller deformation under compression ¡Oil film is not disrupted and friction coefficient remains low during sliding action. ¡Withstands frequent starts and stops. 299
