Large-diameter antifriction bearings, like any other machine part, require careful handling. They should always be transported and stored in the horizontal position; if they must be transported vertically, they will require internal cross bracing. Impact loads, particulary in a radial direction, must be avoided.

State of delivery
(unless otherwise agreed):

Running system
lubricated with one of the quality greases specified.

Gear ring
not lubricated; treatment as for external surfaces.

External surfaces
Tectyl 502-C-EH. Washing with a general-purpose cleaner such as Shell Callina 2306.

Storage
Approx. 6 months in roofed storage areas.
Approx. 12 months in enclosed, temperaturecontrolled areas.
Longer storage periods will require special preservation.

After a long storage period the large antifriction bearing could incur high rotational resistance during start up and running through suction of the seal rim. Careful lifting with a blunt article around the entire circumference and repeated rotation of the large antifriction bearing over 360° right and left this reduces the torque to normal values.
