TEMPERATURE

The normal working temperature of the slewing rings ranges from - 25 up to + 70˚ C. Lower or higher temperatures are possible but require special design provisions by our Engineering Department.

SPEED

The slewing rings can work whether by oscillating motion or continuous motion. It is necessary to check that the circumferential raceway speed remains within the acceptable limits of respective bearing's capacity.

ENVIRONMENT

In case when the working environment is particularly aggressive :

• sea atmosphere,

• dusty or abrasive environment (sand, coal...),particular protection devices must be incorporated such as :

• labyrinths,

• shields,

• oil-bath.

Preventive maintenance operations will be increased to ensure normal operation.

SHOCKS, VIBRATIONS

If the slewing rings are continuously solicited by shocks and/or vibrations, the customer must mention it in the specifications in order to design the right piece.

In any case, it is essential to consult our Engineering Department with the precise operating conditions.
