Transport and handling
Slewing bearings, like any other part of a machine, require careful handling. They should always be transported and stored in horizontal position. For safe handling of bearings which include transport holes, high tensile lifting eye bolts must be used. If they have to be transported vertically, they will require internal cross bracing. The bearing weight must be indicated on the crate or pallet. Impact loads, particularly in a radial direction, must be avoided.
Delivery condition
- Raceway system
The slewing bearings are delivered filled with one of the greases (see table) unless no special lubricant and special grease quantities are required. - External surfaces
External surfaces protected with Cortec VpCI 369/H10. - Gearing
The gearing is not greased. Anti-corrosion treatment as for external surfaces.
Storage
Approx. 6 months in roofed storage areas. Approx. 12 months in enclosed, temperature-controlled areas (temperature > 12°C). Outside storage is not allowed.
Longer storage periods will necessitate special preservation. After the slewing bearing has been stored for a relatively long time, an increased frictional torque may be observed caused by the suction adhesion of the sealing lip. Careful lifting of the sealing lip with a blunt object around the entire circumference and several clockwise and counterclockwise rotations of the slewing bearing through 360 degrees will reduce the frictional torque to normal.
