Cleaning and inspection
Check shaft (spindle) end and/or bearing seat in
the housing for damage indicating that the
bearing has rotated on the shaft (spindle) and/or
in the housing respectively. Replace the damaged
part, if the faults cannot be remedied by polishing
or in some other way.
Assembly
•
Leave new bearings in original wrapping until
ready to fit. The anti-rust agent protecting a
new bearing should not be removed before
use.
•
Use the greatest cleanliness when handling
the bearings.
•
To facilitate assembly and also reduce the
risk of damage, first clean and then lightly
smear the bearing seating on shaft (spindle)
or alternatively in housing, with a thin oil.
•
When assembling ball bearings, the bearings
must be heated in oil to maximum 125 °C.
NOTE
Heat the bearing in a clean container with a
cover.
Use only clean oil with a flash point above
250 °C.
The bearing must be well covered by the oil
and not be in direct contact with the sides or
the bottom of the container. Place the
bearing on some kind of support or
suspended in the oil bath.
