PRG Series Multi-Axis Precision Modules

The Leader in Linear Motors

Overview

PRG MULTI-AXIS PRECISION MODULES

T and H configuration precision gantry

PBA's Rigid Gantry systems was designed for high precision/speed pick-and-place, vision inspection, dispensing stations and high-accuracy placement machines inspection.

PBA's Rigid gantries are available with choice of PBA IronCore or Ironless Direct drive motors in T or H gantry configuration with linear encoder resolutions of up to 0.8mm resolution when used with PBA Maxtune drives.

H-config with dual encoders on the bottom axes available as well for better positional accuracy and repeatability.

PRG gantries look to solve the most demanding of applications through the use of precision assembly methods and high performance motion controllers to achieve stable and consistent motion performance with short settling time, this improving machine throughput and performance.

Application
