Frictionless Linear Guidance Without Wear
If your application requires smooth, precise linear motion, the RB Series rectangular linear air bearings are a strong fit. These slides can replace ball-bearing and crossed-roller slides in applications where lower friction, better smoothness, and long-term accuracy are required.
RB linear air bearing slides offer better straightness, angular deviation, and repeatability than conventional mechanical slides, especially for travel lengths greater than 100 mm / 4 inches. Because the air bearing is inherently frictionless, it eliminates breakaway and running friction, even under high loading.
The fully non-contact, clean bearing interface is virtually maintenance free. Since there is no mechanical wear, the accuracy does not degrade over time the way it can with rolling-element bearings a great advantage in many applications. For situations where air is not available, we also offer mechanical bearing motorized linear actuators.
