Adjusts apron clearance and, on some models, provides overload release, opening or return functions.
Apron Adjustment Cylinder (Apron Adjustment Cylinder)— Impact Crusher Wear part, position 15.
| Installation Position | Outside the housing, connected to the apron adjustment mechanism, position 15 in common layout A. |
| Main Function | Adjusts apron clearance and, on some models, provides overload release, opening or return functions. |
| Replacement Frequency | Low to medium replacement frequency; service or replace for leakage, rod surface damage, pressure drift, insufficient stroke, clevis cracks or bending. |
| Item | Details |
|---|---|
| Material Options | Quenched and tempered 42CrMo/4140 piston rod with a hard-chromed or induction-hardened surface, honed cylinder bore and PU/NBR/HNBR seals |
| Typical Properties and Acceptance Criteria | Design checks must address cylinder strength, piston rod buckling, rod hardness and surface finish, seal compatibility and weld NDT at maximum system pressure and pressure peaks. Factory acceptance includes pressure resistance, pressure retention, internal leakage, stroke, mounting distance and rod-end dimensions. Protection pressure and accumulator or return logic must follow OEM settings. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
