Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Dust Seal Ring
Excludes dust and protects the upper lubrication area.
Dust Seal Ring (Dust Seal)— Gyratory Crusher Wear part, position 05.
Location and Function
| Material Options | NBR, HNBR, polyurethane, FKM or OEM-specified elastomer/composite seal |
| Typical Properties and Acceptance Criteria | Verify compatibility with the lubricant, temperature, dust, cleaning medium and surface speed. Control Shore hardness, tensile and tear properties, compression set, joints and cross-sectional dimensions. Seal life also depends on mating-surface roughness, coaxiality, preload and 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.
