Introduction When working with air bearings, we often describe the quality [...] quality of the stage or bearing itself, straightness and flatness error motions of air bearings can be affected by several outside influences. 4.1 Quality of the mounting surface Air bearing stages require a [...] Linear Air Bearing Slide , 230mm linear travel variant, straightness measurement over full travel when mounted on a granite base vs an optical table (steel) 4.2 Length of travel Since air bearing precision

Top 7 Air Bearing Myths

Top 7 Air Bearing Myths 1. Air bearings are expensive. PIglide air bearings with no motors start at under $2k for a simple linear air bearing slide bearings and under $3k for a small rotary bearing. Planar [...] call a motorized air bearing product an “Air Bearing Stage” and an air bearing without a motor will simply be an “Air Bearing”. Non-motorized linear air bearing. Provides friction less motion for many test [...] house/shop air will do. Clean, oil-free, dry air is required to run an air bearing. Oil and moisture in the air supply will damage the air bearing. If an oil-free compressor is not being used, PI sells air-prep
