RAB Series Standard Linear Air Bearings-Image

If your application requires smooth, precise linear motion Nelson Air's RAB series linear rectangular air bearings are right for you. These bearings can easily replace ball bearing and crossed roller bearing slides and are simple to integrate and use.

They offer better straightness, angular deviation and repeatability than ball bearing slides, especially for travel lengths over 4". In addition, because air bearings are inherently frictionless they do not exhibit breakaway or running friction, even under their maximum loading.

Finally, the totally noncontact, clean nature of air bearings means that they are virtually maintenance free and their accuracy won't degrade over time due to wear. Just add air and precision positioning is at your fingertips.
