Where to mount
Bearings should be installed in a dry, dust-free room away from metalworking or other machines producing swarf and dust.
When bearings have to be mounted in an unprotected area, which is often the case with large bearings, steps need to be taken to protect the bearing and mounting position from contamination by dust, dirt and moisture until installation has been completed. This can be done by covering or wrapping bearings, machine components etc. with waxed paper or foil.
