Installation · Lubrication · Maintenance (ILM)
®
Does not apply to bearings with specific ILM instructions – for replacement
deliveries it is essential to get into contact with the machine manufacturer
regarding installation, lubrication and maintenance.
Mechanical machining of the bearing connection surfaces
on the connecting structure is required if the values are
exceeded. The mounting position of slewing bearings
must correspond to that shown in the drawing.
The corrosion protection can be removed with an alkaline
cleaner. Solvent must be prevented from coming into
contact with the seals or the raceway. Remove the pro-
tective coating from the upper and the lower mounting
surfaces of the slewing bearing as well as from the gear.
Note
The corrosion protection can easily be removed,
for example, using a biodegradable alkaline cleaner.
Advantage
Rapid removal of the corrosion protection
and low environmental impact.
Hardness gap
The unhardened zone between the beginning and the end
of the hardened region of the raceway is marked with an
"S" on the inner or outer diameter of each bearing ring.
On the gear ring, the hardness gap is marked on the
axial surface. Wherever possible, the hardness gap "S"
must be positioned outside the main load-carrying areas.
If the main working area for the application is known,
then the hardness gap of the ring loaded on the circum-
ference must also be positioned outside the main load-
carrying area.
Gearing
Entanglement hazard due to
exposed gear
• Keep hands away from moving parts
The backlash is adjusted relative to the three gear
teeth marked in green and should be at least
0.03 – 0.04 x module. After the final tightening of the
bearing, the back lash should be rechecked over the
entire circumference. A tip edge radius and a tip relief
must be provided on the pinion (see the "Gearing"
chapter in the catalog Rothe Erde
www.thyssenkrupp-rotheerde.com).
