Individual Part

Main Shaft

The central load-bearing shaft supports the crushing head and transmits gyratory crushing loads. The shaft and its external protective sleeve are separate parts.

Gyratory crusher mainshaft and mainshaft assembly identification diagram
The mainshaft assembly diagram distinguishes the shaft body, protective sleeve, head nut, mantle and adjacent mating parts.

Main Shaft(Mainshaft) is an individual gyratory crusher part. Verify its interfaces with adjacent mainshaft, spider, liner, eccentric and hydraulic system parts against the actual machine arrangement.

Installation position and function

Installation PositionRuns along the crusher centreline through the crushing head, eccentric drive and hydraulic support areas.
Main FunctionSupports the crushing head and mantle, transmits gyratory loads and receives axial support from the hydraulic adjustment system.

Drawing-based manufacture and technical review

For drawing-based manufacture, check the mainshaft body and protective sleeve separately. Confirm journals, tapers, threads, fits, material, forging grain flow, heat treatment, mechanical properties, non-destructive testing, surface finish and straightness.

Required Ordering / RFQ Information

  • OEM, complete model, serial number and assembly or part number;
  • Latest drawing revision, dimensions, unit weight, critical tolerances and assembly interfaces;
  • Current material, heat treatment, hardness, mechanical properties and nondestructive testing requirements;
  • Failure photos, wear measurements, crack locations, current service life and target life;
  • Fit with adjacent parts, fastening, lubrication, sealing and assembly/disassembly requirements.
Parts or assemblies with the same name can differ between brands, series and production periods. Confirm the complete model, drawing number and revision before manufacture.
