Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Spider Bushing
Guides the upper mainshaft and provides a replaceable low-friction bearing surface.
Spider Bushing (Spider Bushing)— Gyratory Crusher Wear part, position 19.
Location and Function
| Material Options | C93200 leaded tin bronze or OEM-specified bearing bronze |
| Typical Properties and Acceptance Criteria | C93200 typically offers resistance to seizure and good embeddability, with hardness commonly around 60–90 HB; the drawing governs final composition and hardness. Key checks cover centrifugal casting soundness, coaxiality, cylindricity, bore surface, oil grooves, interference, running clearance and anti-rotation features. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes; contact fatigue, lubricant contamination, temperature rise, seizure and seal failure |
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.
