Cone Crusher socket liner

The cone crusher socket liner, a replaceable wear-resistant component in the socket’s bearing cavity, acts as an interface between the rotating main shaft and stationary socket. It protects against wear, reduces friction (≤0.15 with lubrication), distributes loads, and compensates for minor misalignment, requiring good wear resistance and lubricant compatibility.​ Structurally, it is a cylindrical/flanged sleeve with a liner body (bronze, babbitt, or bimetallic materials), inner bearing surface (Ra0.8–1.6 μm with oil grooves), outer surface (interference fit), optional flange, lubrication features, and chamfers, with 5–15 mm wall thickness.​ Manufacturing involves casting (centrifugal/sand) for bronze liners, plus heat treatment and machining, or steel shell preparation, bearing layer application (sintering/roll bonding) and machining for bimetallic ones.​ Quality control includes material testing (composition, hardness), dimensional checks (CMM, roundness testing), microstructural analysis, performance tests (friction, wear), and fit checks, ensuring it protects components for efficient crusher operation
