A gyratory crusher includes an eccentric having an inner slide bearing surface and an outer slide bearing surface, the inner slide bearing surface defining, together with an opposing slide bearing surface, an inner slide bearing. The outer slide bearing surface defines, together with another opposing slide bearing surface, an outer slide bearing. The eccentric is rotatably connected to a crusher frame so as to allow a rotation about an eccentric axis of rotation, which is fixed relative to the frame. The eccentric axis of rotation is defined by one of the inner and outer slide bearings. The inner slide bearing has a total height-to-diameter quotient (H/D) of less than 1.0.

A gyratory crusher spider bushing assembly is positionable radially intermediate a topshell spider and a crusher main shaft. The assembly includes a main body to which is attached a radially inner annular wear collar. The collar is formed from a material having enhanced wear resistance than the material of main body.
