Frictionless-Motion Mounted Linear Air Bearings | McMaster

Float bearings on air for precise, frictionless movement. Unlike traditional bearings that can wear your shaft down, these bearings are suspended using pressurized air for linear and rotary motion. Since there’s no friction, they glide smoothly and silently without wearing over time. These are self-aligning bearings, so they compensate for some shaft misalignment.

What Are the Best Frictionless Bearings on the Market?

Nov 13, 2018· It is designed with small indentations or divots. The balls go into the divots as they roll over the track. This motion speeds up or slows down as the balls are rolling and they will never collide. This invention makes the traditional cage design obsolete. Without the cage, the bearings have ten times less friction.

Air Thrust Bushings for frictionless, rotary motion

In order to prevent linear motion, a thrust face is added that is also made from porous carbon. These bushings are found in many rotary appliions such as turbochargers in high-performance automobiles. Thus these thrust bushings could be the answer, if you’re looking for frictionless, rotary motion that doesn’t move linearly.
