RotoRingTM rotary tables provide superior angular positioning and are 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, low profile, direct drive configuration.
Large area air bearings provide sufficient stiffness for large payloads and maximizes performance in respect to wobble and run-out. Radially distributed brushless RotoLinear motoring modules provide high positioning stiffness during rotary indexing and when installed on moving XY tables.
These rotary tables provide unlimited rotation capability and precise velocity control.
RotoRingsTM feature "large open center design". When used in processing 12" semiconductor wafers, every area of the wafer can be accessed.
In general automation applications large open center offers the opportunity to access parts from inside and outside of the table simultaneously. This feature allows robotic devices, pick and place and ancillary tooling to be mounted inside the table, saving floor space and reducing parts handling with increased productivity.
