Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Apron Adjustment Cylinder
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.
Location and Function
| 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 |
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.
