HRT-Hydrostatic (Oil Film) Bearing Rotary Tables

Ultra-Precision/High Stiffness Direct Drive Rotary Axis

ABTech's Ultra-precision HRT-Series rotary tables combined with high torque brushless DC servo motors, digital drives, and high resolution rotary encoders provide the highest performing direct drive rotary tables on the market.

The 440C hardened stainless & electroless nickel plated steel bearing components provide excellent way surfaces and machine tool durability for these ultra-stiff rotary tables.

ABTech incorporates a modular design approach which includes turn-key engineering solutions for the end user.

These tables are ideal as an additional axis in diamond turning/milling applications, as well as heavy duty positioning, machining, grinding, and more.
