Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Spider Bushing Oil Seal
Retains spider bushing lubricant and excludes water and dust.
Spider Bushing Oil Seal (Spider Bushing Oil Seal)— Gyratory Crusher Wear part, position 20.
Location and Function
| Material Options | NBR, HNBR, FKM or PTFE/elastomer composite seals |
| Typical Properties and Acceptance Criteria | Select for compatibility with the grease or oil, temperature, dust and oscillation speed. Control seal lips, joints, hardness, compression set and installation preload. Worn mating faces, eccentricity and abnormal spider bushing clearance can greatly shorten seal life. |
| Principal Failure Mechanism | Sliding and three-body abrasion, local impact and cracking around fastener holes; contact fatigue, lubricant contamination, overheating, seizure and seal failure; wear, ageing, extrusion, fluid incompatibility and leakage |
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.
