We offer several types of rotary motion components; rotary air bearings, air bearing spindles, rotary ball bearings, and combination rotary air and ball bearing tables. Those each have a variety of configurations and options available. As precision motion experts we will help you configure exactly what you need and if our standard product designs and options don’t fit your unique application we can provide a custom solution.
ABTech’s AT series manual spin and direct-drive air bearing rotary tables, with dual thrust plate bearing designs and diameters from 4 to 16 inches (100mm to 400mm) provide micro-inch (sub-micron) accuracy at lower speeds (0 RPM to 2000 RPM), with nearly absolute repeatability. The HDRT series of heavy duty manual spin and gear motor driven rotary tables, with thrust plate diameters from 18 to 36 inches (457mm to 915mm), handles loads from 2500 to 5000 lbs.
ABTech’s programmable, high-speed air bearing spindles provide reduced error motion (as low as 1 micro-inch or 0.025 microns). These frictionless spindles have been G0.4 balanced and are thermally stable up to 10,000 RPM or more. The direct drive brushless DC motor comes with a wide range of motor, torque and load sizing.
Rotary tables in the ABT series combine ultra-precision air bearings for lift with radial ball bearings specifically for heavy, larger diameter parts that require precise rotary motion in low profile applications.
ABTech designed these precision mechanical bearing tables with pre-loaded angular contact bearings and a ground internal shaft to provide an accurate rotational axis for general industrial applications. The BT series is completely portable because it operates without an air supply.
All our products are designed, manufactured, assembled and tested exclusively by ABTech at our Swanzey, New Hampshire facility. Every rotary motion product reflects ABTech’s high quality standards and exemplifies our company-wide commitment to “Pride in Precision” craftsmanship.
