WebWhy do air bearings not work on poor floor conditions? The floor over which the load is being moved is a critical part of the air bearing's efficient operation. It stands to reason that any holes or cracks in the floor will result in loss of air pressure and volume. Likewise, large vertical floor projections are a problem. WebAs with conventional bearings, air bearings constrain the relative motion of a desired object to one or more axes. Nearly every conventional bearing has an analogous air bearing … si 109 of 2019 https://itworkbenchllc.com
