Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Spider underside wear liner
Protects the underside of the spider casting to help extend the service life of the spider assembly.
Spider underside wear liner (Spider Underside Wear Liner)— Gyratory Crusher Wear part, position 31.
Location and Function
| Material Options | High-manganese steel, martensitic wear-resistant cast steel or quenched and tempered wear plate |
| Typical Properties and Acceptance Criteria | For conditions where the spider is buried in feed or abrasive ore wears its underside. Requires wear resistance, adequate impact toughness, secure fastening and full coverage. Pay particular attention to liner edges, bolts, joints and stress concentrations around the central bushing. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
