Mounting and Dismounting of Rolling Bearings
Store bearings in their original package in order to protect them against contamination and corrosion. Open package only at the as-sembly site immediately prior to mounting. Larger bearings with relatively thin-walled rings should not be stored upright (Figure 1a) but flat and supported over their whole circumfe-rence (Figure 1b).
