Bearings bring no backlash
The SuperZ/Macro-Flexure system is a zero backlash axis bearing without linear bearings or rolling contact.
The SuperZ/Macro-Flexure system is a zero backlash axis bearing without linear bearings or rolling contact Linear motion is derived by rolling shear members that are quite wide providing high shear and moment stiffness even though they are as thin as 0.003in

Power module attains new speeds
The ServoNut power module is a high force option for most motion chassis.
The flexures themselves are highly preloaded and resist reasonable overload conditions.
A parallelism from top to bottom of 1um is achievable throughout the stroke.
Another primary feature it is its low profile nature.
The Macro Flexure configuration allows for relatively long travels in the z-axis relative to its height, typical stroke being half of the overall height, with no possibility of binding.
Further important features of the design are its extremely low particle generation capability, vacuum compatibility and zero maintenance required.
Lead screws, ball screws, linear motors and voice coils, rack and pinion, piezoelectrics, cams, literally all types of prime mover can be used, though when matching up a drive to the super-Z bearing, one would want to select a drive with the same cleanliness and zero maintenance nature.
Bell-Everman will be providing voice-coil, piezoelectric and ball-screw prime movers as standard, with direct reading linear encoders in resolutions to 5nm.
