Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Dust shell seal / dust seal ring
Prevents dust from entering the adjustment mechanism and lubrication areas, maintaining separation of the dust-sealing air and lubrication chambers.
Dust shell seal / dust seal ring (Dust Shell Seal)— Cone Crushers Wear part, position 15.
Location and Function
| Material Options | NBR, HNBR, polyurethane or an OEM-specified elastomer or polymer |
| Typical Properties and Acceptance Criteria | Check compatibility with lubricants, temperature, dust and cleaning media. Control hardness, tensile and tear properties, compression set, joint quality and dimensional stability. Seal life also depends on mating-surface wear, concentricity, compression and the dust-sealing air supply. |
| Principal Failure Mechanism | Wear, aging, extrusion, medium 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.
