Slewing Bearings for Deck Crane Machine Wind Power And Machinery Construction

Please check the weight of the ring to ensure slings and/or chains are of sufficient capacity!Shock loads, especially in the radial direction, must be avoided as this may damage the raceways.If stacked on a pallet then care must be taken not to dislodge seal strips or grease fittings during movement. Wooden or rubber spacers would be of benefit between each bearing. External gear teeth (especially) should be protected from any impact damage.

As supplied slewing rings are generally packed for storage in a covered store and for a period not exceeding 6 months. Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.

In extreme cases after long term storage bearings may need professionally reconditioning before installation.When unwrapping, care must be taken not to cut and damage the integral seals.
