Gyratory crusher spider bushing assembly

A gyratory crusher spider bushing assembly comprising:

• an annular main body extending around an axis of the assembly, the main body having a radially outward facing surface and a radially inward facing surface, the main body being formed from a first material, the main body including a first end having a mount flange extending radially outward and a second end;
• an annular wear collar positioned at the inward facing surface and extending radially inward from the main body, the collar being mounted at the main body to prevent independent rotation of the collar about the axis relative to the main body, the collar including a second material having a wear resistance greater than the first material;
• an axial length of the collar corresponding to a distance between a first end and a second end of the collar that is less than that 75% of an axial length of the main body, the axial length of the main body corresponding to a distance between the first end of the main body and a region of the main body aligned at the same axial position as the second end of the collar, the collar being positioned axially closest to the second end of the main body relative to the first end of the main body;
• and
• a radially extending abutment at the inward facing surface and/or the collar, the abutment being arranged to axially separate and prevent the collar from moving axially towards the first end of the main body, wherein the inward facing surface of the main body is aligned transverse to the axis of the assembly to tilt radially outward such that a radial separation distance of the inward facing surface at an axial position of the first end of the main body is more than a radial separation distance of the inward facing surface at an axial position at or towards the abutment.
