ShopBot Tools introduces the PRS Retro Z Axis. Comprised of an extruded aluminum Z beam and a captured bearing system, the Retro Z allows owners of older ShopBot PR and PRT machines to upgrade to a newer PRS-style Z axis. The PRS Retro Z Axis increases rigidity and tool accuracy in the older-model ShopBots, the company says, permits 8 in. (203mm) of stop-to-stop vertical travel and will not limit a tools’ current travel in the X- or Y-axes.
Multiple hole locations on the mounting plate allow for the Retro Z to be fastened at variable heights, and a corresponding motor plate is included to allow for the mounting of a customer’s existing Z motors to the Retro Z Axis.
