Metric Air Bushings

New Way® Metric Air Bushings are designed for rotary or linear metric shaft-based applications. Built on our foundational Porous Media TechnologyTM, New Way Metric Air Bushings remove friction in the form of a ‘tube’ of porous media. This permeable surface naturally distributes an even, yet stiff, layer of air, to provide the necessary lift/gap for operation.

This unique method of removing friction offers enhanced precision unavailable to rolling element systems, making them ideal for applications requiring precision rotary and linear motion concurrently. Maintenance downtime is also significantly reduced as burdensome lubrication requirements become obsolete. These advantages make New Way Metric Air Bushings a win-win for operations!

Air bushings can be paired with a pillow block housing unit for a simple interchange with existing rolling element systems. Co-polymer O-rings are provided for ease of installation into the pillow block to compensate for parallelism errors of up to .002″ over the length of the shaft.

New Way Metric Air Bushings are offered in six standard metric sizes to accommodate standard metric precision steel shafts. Custom sizes are also available.

Applications

With friction removed, New Way Air Bushings offer a number of operational efficiencies available across industries. Several example industries and the benefits they are seeing are listed here. Feel free to contact us today directly for use in your application!

Converting
  • Conveyance of products uses significantly less energy, with no downtime driven by lubrication or wear
  • Higher speeds are achievable, increasing production yields, as concerns of heat issues dissipate
Automotive
  • The non-contact nature of New Way Air Bushings is an ideal application to test dynamic forces such as torque, fatigue, and frame integrity
  • Achieve greater confidence in test results as the asynchronous and synchronous errors associated with ball bearings are overcome
  • The repeatable frictionless linear motion ensures precision for situations where lives depend on the accuracy of the test results
Energy
  • When contact is removed, energy costs decrease while simultaneously achieving higher speeds
  • Improved efficiency of turbine operation through lower operational costs and reduced maintenance
Semiconductor
  • Achieve high-speed, short-stroke precision with repeatable sub-micron positioning, all while meeting clean-room compliance
  • No contact or wear translates to reduced maintenance costs and downtime when compared to ball bearings which must often be replaced
