Apron Pivot Pin Bushing

Name: Apron Pivot Pin Bushing
Brand: ANRANST

Provides the apron pivot or release point and transfers impact and adjustment loads.

Apron Pivot Pin Bushing (Apron Pivot Pin and Bushing)— Impact Crusher Wear part, position 17.

Installation and Function

Installation Position	At the apron pivot and adjustment mechanism connections, position 17 in common layout A.
Main Function	Provides the apron pivot or release point and transfers impact and adjustment loads.
Replacement Frequency	Medium replacement frequency; assess as a set for excessive clearance, uneven wear, seizure, pin cracks, bushing movement or lubrication failure.

Materials and Mechanical Properties

Item	Details
Material Options	Quenched and tempered or induction-hardened 42CrMo/4140 pins with copper alloy, hardened steel or OEM-specified composite bushings
Typical Properties and Acceptance Criteria	Pins require core toughness, surface wear resistance, bending fatigue strength and shear resistance. Bushings need resistance to seizure, embeddability and the ability to operate under boundary lubrication. Control pin bore coaxiality, pin roundness and hardened case, bushing interference, running clearance, oil grooves and dust protection. Replacing the pin without correcting a worn bore can cause rapid recurrence.
Principal Failure Mechanism	Sliding or three-body abrasion, localized impact and cracking around fastener holes; contact fatigue, lubricant contamination, temperature rise, seizure and seal failure

Material and Design Considerations

Identify material hardness, particle size, abrasiveness, moisture, temperature, pH, impact and tramp material;
High hardness does not replace core toughness, fatigue strength, corrosion resistance or high-temperature performance;
For composite, hardfaced, ceramic and elastomer designs, assess substrate bonding, edge protection, fastening and maintainability;
For parts that mate with shafts, gears, seals, roll surfaces or housings, control fits, tolerances, surface finish and assembly clearances together;
Assess material upgrades using cumulative throughput, dimensional wear, failure modes, product quality and downtime costs.

Required Ordering / RFQ Information

Equipment manufacturer, machine model, serial number, part number 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.
