Frictionless-Motion Mounted Linear Air Bearings
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.

High-Capacity Air-Glide Dollies
Also known as bearing movers, air casters, and air bearings, these dollies float loads on a cushion of air. They work well on large, unevenly distributed loads. As air escapes out of the air diaphragm located under the top platform, the load is lifted for easy, frictionless movement in any direction over smooth surfaces. The low lift height reduces the risk of injury to personnel and damage to other equipment.
