Eccentric stud type track rollers are easily registrable respect to
raceways, moreover if more studs are assembled together load
can be uniformly distributed
Rollers can easily rotate up to get an eccentric form, thanks to
the slot inserted on lateral part of stud (see ‘V’ dimensions in the
following tables)

lubrication hole, located on lateral side of the stud, only eccentric
studs cannot be relubricated from the thread as the assembled
eccentric ring avoids oil penetration.
