Compact Direct Drive Rotary Table with Air Bearings
RTH-4 rotary tables provide superior angular positioning and designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives.
They combine axial brushless RotoLinear motoring modules and planar air bearings in a compact, direct drive configuration.
Large area air bearings provide sufficient payload stiffness and maximizes performance in respect to wobble and run-out.
Radially distributed RotoLinear motoring modules provide high positioning stiffness during rotary indexing and when installed on moving XY tables.
These tables provide unlimited rotation capability and are compatible with standard micro-stepping drives and indexers.
Can also be equipped with IntelLiCoder feedback and driven as a commutated brushless motor.
RTH tables feature center bore (aperture) for user to install cabling, vacuum lines or fixtures.
