Gyratory crusher spider bushing

A gyratory crusher spider bushing arranged for positioning radially intermediate a topshell spider and a crusher main shaft configured for gyroscopic precession within a crusher, the bushing comprising:

• a cylindrical main body with an inside surface and an outside surface centered around a mainly vertically orientated longitudinal axis;
• a collar arranged in connection to a top end of the gyratory crusher spider bushing, wherein the inside surface includes a fulcrum point having a smallest diameter of the gyratory crusher spider bushing, wherein a fulcrum angle defines an inside surface inclination above/below the fulcrum point in relation to the longitudinal axis, and wherein an inside length is defined from the fulcrum point to a top end of the collar;
• and
• a plurality of longitudinal cutouts located at the inside of the main body, wherein the cutouts are partly recessed in the inside surface, and wherein the cutouts have a length of which a lowermost part is located at or above a region of the fulcrum point.
