. Bearing
3 DMF components
Large and small ball bearing
The primary mass is fitted with a turned hub on which
the large-size ball bearing is fitted.
A hub flange with the bearing seat (turned or drawn) is
mounted onto the primary mass. The bearing seat can be
adjusted to mount a small ball bearing – as shown here
– or a plain bearing.
Plain bearing
In comparison with ball bearings, plain bearings take up
less space and are more simply designed. In spite of their
low manufacturing costs, they can be universally used
and, if necessary, can be designed to allow axial motion.
