INSTALLATION AND
MAINTENANCE OF

SLEWING BEARINGS

Slewing bearings must always be transported with their axis of rotation in a vertical direction and properly supported, so that any deformations are impossible. In case of larger slewing bearings, when a tilted position cannot be avoided, the use of a supporting structure must be used to ensure adequate support, especially in the radial direction.

More information about the transport you can find in our technical catalogue. In order to transport the bearings safely, carefully read the instructions.

In case of any additional questions, you can contact us on rotis@rotis-lj.si

The slewing bearing must be stored indoors in a dry and dust-free location and they must not be exposed to direct sunlight. The recommended ambient temperature for storing is between 10°C and 40°C, and the maximum relative humidity should not exceed 65%.

More information about the storing you can find in our technical catalogue. In order to avoid the damages caused by outside influences, carefully read the instructions.

Rotis large slewing bearings are delivered in “plug and play” condition, therefore the slewing bearing raceway is completely filled with grease on a mineral base oil and a lithium soap thickener for extreme pressures and anti-wear properties. The slewing bearing gear is protected with oil during shipping. If longer storage times are requested, additional protection is applied. Castrol SPHEEROL EPL2 greases are generally used for raceway systems or in the case of elevated temperatures, Mobil Mobilith SHC 460.

During installation and commissioning, it is necessary to re-lubricate the slewing bearing until grease exits from beneath the seal. While re-greasing, the slewing bearing must be rotated.

More information about the storing you can find in our technical catalogue. In order to avoid the damages caused by outside influences, carefully read the instructions.

Slewing bearings are delicate and precise machine elements, therefore strict standards apply during their handling, installation and maintenance.

The slewing bearing is normally wrapped in anti-corrosive paper and foil, so the package must be carefully cut and removed, that the seals, surface coating etc., are not damaged. In case of any damage to the product, please contact us.

Prior to installation, the contacting surfaces and gear teeth must be cleaned at least of any anti-corrosive solvents, remains of grease or any other impurities. Only cleaning solvents and cloths, which do not damage the slewing bearing, i.e. seals, surface coating, etc., can be used. Slewing bearings must never be washed with high pressure washers. During cleaning, no impurities must be allowed to penetrate into the raceway system.

More information about the installation you can find in our technical catalogue.

In case of any additional questions, you can contact us on rotis@rotis-lj.si.

Each maintenance task must be properly recorded and documented. Any deviation from the expected values must be checked and verified by a responsible specialist and, if needed, communicated to Rotis.

In order to assure the optimal performance of the slewing rings, regular maintenance must be carried out.

More information about the maintenance you can find in our technical catalogue.
