The load-bearing capabilities of our air bearings are guaranteed on finished surfaces with a mean roughness value of 16μm. Lapped surfaces are typically in the 2-8μm range while typical grinding operations produce a finish between 8-63μm. WebDuring startup and shutdown, the bearing and shaft make rubbing contact until sufficient rotational speeds pump air into the bearings. To reduce wear, a dry lubricant coating is applied to the foil and shaft. Most current foil-bearing applications use a polymer coating such as Teflon ® that is limited to about 400 °F. can pregnant women eat albacore tuna
