Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Labyrinth Seal Rings
Uses a non-contact labyrinth path and a grease barrier to keep dust out of the bearing housing.
Labyrinth Seal Rings (Labyrinth Dust Seal)— Jaw Crushers Wear part, position 16.
Location and Function
| Material Options | OEM-specified materials such as cast steel, forged steel, ductile iron or bronze |
| Typical Properties and Acceptance Criteria | Sealing performance depends mainly on the number of labyrinth stages, radial and axial clearances, coaxiality, surface finish, grease purge path and freedom from rubbing. Material hardness is secondary. Measure the mating parts as a set and inspect for wear marks, deformation and cracks. Reducing clearances without design approval can cause overheating or seizure. |
| 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.
