(1888PressRelease) May 02, 2012 - Newly released RTH Series rotary tables combine planar air bearings and RotoLinear motor technologies in the compact, direct drive configuration.
These rotary tables eliminate friction, backlash and the wear problems associated with worm gears and belt driven stages.
Small 1.5" height profile tables manufactured with diameters 4", 6", 8" and 12", operate on air bearings for frictionless, maintenance free operation, and can be supplied with aperture opening through the center.
Torque ranges from 5 to 50 lb*ft, resolution up to 1 arc-sec, repeatability 5 arc-sec, speed up to 200 rpm with unlimited rotation.
Series RT tables are compatible with standard micro stepping indexer/drivers and offer a low cost, compact envelope direct drive rotary positioning systems and can also be supplied with high resolution tape encoders for ultra-precise positioning and closed servo loop operation.
Typical applications include semiconductor assembly equipment, wafer inspection and cutting, fiber-optics alignment, optical applications, precision part indexing and robotics.
Low profile direct drive rotary tables.
