Fluid bearing - Wikipedia

Fluid bearings are noncontact bearings that use a thin layer of rapidly moving pressurized liquid or gas fluid between the moving bearing faces, typically sealed around or under the rotating shaft. The moving parts do not come into contact, so there is no sliding friction; the load force is supported solely by the pressure of the moving fluid.

How to calculate coined static load - Linear Motion Tips

While dynamic load capacity is used to calculate bearing life, static load capacity indies how much load the bearing can withstand before permanent damage occurs to the balls and/or the raceways. Even when they’re not moving, linear guides often experience a coination of both forces and moments, all of which contribute to the coined static load that the bearing sees.
