40mm ID Air Bushing

40mm ID Air Bushing

Third largest of the New Way metric air bushing line, the 40mm ID size provides a good balance of size and 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.
