igus testing method for measuring the tolerance of drylin linear plain bearings

To ensure the correct function of a drylin R linear plain bearing, it is necessary to use the bearing with a defined minimum Part No. Test force Øi test housing Min. bearing Øi Max. bearing Øi

oversize (bearing clearance). The quality control of this part is carried out with a plug gauge test. For this purpose, specific force (plug gauge falls) (plug gauge sticks)
is defined with which the plug gauge is loaded when the plain bearing is tested. [N] [mm] [mm] [mm]
