Frictionless-Motion Mounted Linear Air Bearings
Bearing in Housing
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. They must be connected to a compressed air system.
