4.1 Dry bearing

The functional criteria for a radial bearing used in fine mechanics ( 9 ) are, for example:

• maintenance-free and preferably dry-running;

• tolerance of high relative humidity ;

• minimum friction losses.

The key operating parameters are as follows:

• continuous slip ;

• normal load: F _N = 5 N, i.e. p ₀ " 0.15 MPa ;

• rotation speed: n = 10 tr·min ^–1...
