QuickTrak Linear Guides reduce design and installation costs because they are easily built into equipment and are available off-the-shelf from Bishop-Wisecarver Corp., Pittsburgh, Calif., (bwc.com). The guides provide long length, antifriction movement, and reduced noise and vibration. The belt or screw-driven devices are ideal for light industrial use in laboratory, medical, and packaging applications that need precision guided motion and corrosion resistance, according to the developer. Multiple holes on the wheel plate make it easy to mount single and double axis gantries. The units require minimal attention between long intervals. Performance can also be upgraded with peripheral accessories.
