Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
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.
| Installation Position | Dust seal chamber outside the eccentric shaft bearing; no separate position number is shown in the layout. |
| Main Function | Uses a non-contact labyrinth path and a grease barrier to keep dust out of the bearing housing. |
| Replacement Frequency | Low to medium replacement frequency; replace for dust ingress, contaminated grease, rubbing or excessive clearance. |
| Item | Details |
|---|---|
| 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 |
