Quality ConstructionThese tables feature a rigid pair of quality angular contactbearings which produce smooth table top rotation. The lowbacklash precision worm gear drive provides exceptional ac-curacy and repeatability. Load capacities to 225 pounds 102kg) are available, with table top diameters of 6, 8, 10, and12 inches. All aluminum components have a black anod-ized nish and each table has a standard NEMA 23 motormount. Threaded steel inserts in the table top provide foreasy mounting of the user load, while the 0.75 inch (19 mm)diameter through hole provides easy access from below.With 3 different gear ratios for each table top, the 300 seriestables perform well in either high speed or high resolutionapplications. Mounting a 300 series rotary table directly toany of L IN T ECH 's linear positioning tables, produces aunique multi-axis system.

Standard Features - 400 SeriesSingle Axis Rotary Table
L IN T ECH 's 400 series positioning tables offer precisionperformance and design exibility for use in a wide varietyof Motion Control applications.
Quality ConstructionThese tables feature a rigid pair of 4 point contact radialbearings which produce smooth table top rotation. The lowbacklash precision worm gear drive provides years of excep-tional accuracy and repeatability. This rugged constructionoffers load capacities to 1000 pounds (453 kg) with a 5.48inch (139 mm) table top diameter. Threaded steel insertsin the table top provide for easy mounting of the user load,while the 4.5 inch (114 mm) diameter through hole pro-vides easy access from below. The NEMA 34 mount can berotated 360 degrees around either side of the table. With 5different gear ratios, the 400 series tables perform well ineither high speed or high resolution applications.
Flange can be mounted on eitheside of housing, and located in position thru 360 degrees.

L IN T ECH provides two different types of couplings that can be used to mount a motor to a 300 series positioning table.These couplings compensate for misalignment between the motor shaft & worm gear drive shaft extension. This provides fortrouble-free operation as long as certain precautions are taken. The connected motor output torque should never exceed thecoupling maximum torque capacity. Larger capacity couplings may be required for applications having high accelerations, largeback driving loads, high torque output motors, or servo motors.

0.85 inch (21,6 mm) is the largest diameter coupling allowed to be used with the 300 series because of the internal motor mount clearance.
