75mm VPL Air Bearing
S207501S207501

The 75mm size falls exactly in the middle of the New Way vacuum preloaded air bearing line, providing a good balance of size and 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.
