JBT2300-slewing bearings - SlideShare

13/9/2015· Therefore, the static reference load of the slewing bearing should be as follows: Fa′= 1750 kN× 1.45 = 2537.5 kN M′ = 5566.3 kNm × 1.45 = 8071.1 kNm The bolt’s computed load should be: Fa = 1750 kN M = 5566.3 kNm Note: The load used in the bolt check table is not the static reference load of the slewing bearing!

Bearing (mechanical) - Wikipedia

Bearing (mechanical) A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the
