9、ow rotations and slight oscillations under load. They are intended for use in the hubs of torsion levers and in separated supports. The bearings defined in this standard shall be used in the temperature range - 54 C to 150 C. However, as they are lubricated with the following greases (see EN 2337):

10、- ester type extreme pressure grease (code A), operating range -73 C to 121 C or - synthetic hydrocarbon type extreme pressure grease (code 6). operating range - 54 C to 177 C, their field of application when lubricated with code A grease shall be limited to 121 C. 2 Normative references This Europe
