S209001S209001 – 90mm VPL Air Bearing


90mm VPL Air Bearing

Largest of the New Way vacuum preloaded air bearing line, the 90mm size provides the scale necessary for more significant load-carrying capability. Because both the “x” and “y” axes can be supported by a single bearing plane, this VPL offers advantages that conventional air bearings cannot touch. It is also easy to apply, replace or change.
