Rectangular Bonded Air Bearings

New Way^® Air Bearings’ Bonded Bearings offers a low-profile version of our flat rectangular bearings that can be adhered in place using our signature vacuum replication process. They’re an essential component to our linear slides that we now sell separately to incorporate into those space constrained linear applications.

The nature of our bonded bearings allows for the use of vacuum pressure to provide accurate positioning of the bearing before bonding into place with epoxy. Once the bearings are secured, you will switch from vacuum to airflow through the porous carbon substrate that makes our bearings truly frictionless.

Air is forced through the millions of submicron holes that are naturally present in our Porous Media Technology™. The passageways constrain the air so that when it reaches the surface, a uniform, stiff cushion forms between the bearing and the opposing surface. This creates no contact motion and is cleanroom compliant since the Porous Media™ also acts as a filter.

Heat and noise are essentially eliminated since parts are never in contact. Crashes are a thing of the past due to the resiliency of porous media and its ability to continue to create stiff air cushions even when the surface is damaged.

Clean Room Compliant

The unique use of porous media in air bearings makes them ideal for clean room use. Not only is less air used in air bearings when compared to orifice-based air bearings, but the air is evenly distributed by the porous media. Both of these features minimize the potential of currents or eddies in the clean room and its damaging impacts on production.

Another benefit of the use of porous media is its ability to perform as a sub-micron filter for the air emitted. Testing indicates the bearing satisfies the requirements of Class 1 (ISO class 3) cleanliness, with airborne particulate concentrate limits of less than 1,000 x 0.1μm particles / m3.

Bonded bearings are available in many sizes to fit your specific application. New Way’s customer support team is standing by 24/7 to discuss your options.
