50mm ID Air Bushing

50mm ID Air Bushing

Second largest of the New Way metric air bushing line, the 50mm ID size provides the scale necessary for more significant load-carrying capability on metric shafting. These porous media bushings are an inexpensive way to achieve frictionless linear motion, and compare favorably with conventional rolling element bearings across virtually every performance characteristic. They are also easy to apply, replace or change.
