20mm ID Air Bushing
S302001S302001

Second smallest of the New Way metric air bushing line, the 20mm ID size provides excellent load-carrying capability with the flexibility to fit into tight designs 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.
