Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Dust collar
Works with the sealing system to exclude dust from the gear and plain bearing lubrication areas.
Dust collar (Dust Collar)— Gyratory Crusher Wear part, position 25.
Location and Function
| Material Options | OEM-specified cast steel, ductile iron, copper alloy or wear-resistant composite |
| Typical Properties and Acceptance Criteria | Material selection depends on whether the design uses a contact seal, labyrinth or air seal; the part name alone is insufficient. Control roundness, concentricity, sealing clearance, surface roughness, wear resistance and dimensional stability. Inspect the collar together with the dust seal, bottom shell and eccentric assembly. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
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.
