Description

Product Name: Part Number 442.7259-00 CH440 Main Shaft Assembly |Aftermarket Sandvik Cone Crusher Spare Parts | High Alloy Forged Steel Wear Resistant Component
Material：
Adopt high-strength forged alloy steel as core raw material for CH440 main shaft assembly, customized heat treatment process including quenching and tempering to improve tensile strength, fatigue resistance and wear resistance. Custom forging size, alloy ingredient and machining production can be customized per client’s technical drawings or part numbers for all kinds of Sandvik aftermarket cone crusher parts and crusher parts.
Function
Main Shaft Assembly is the central rotary core aftermarket cone crusher parts tailor-made for Sandvik CH440 cone crushing equipment. Installed inside the eccentric sleeve, this heavy-duty forged main shaft bears huge eccentric swing torque, continuous rotary friction and heavy impact load during hard rock crushing process. Cooperating with inner bronze bushings, the shaft transfers crushing force to mantle for material compression and fragmentation; matched internal lubrication structure reduces abrasion between rotary components, ensuring stable long-time running of full Sandvik CH440 crusher unit.
Structure difference note: Our aftermarket CH440 main shaft assembly excludes mantle accessory, separate mantle spare parts can be matched and purchased together from our full set Sandvik crusher parts supply list.
Our factory supplies complete one-stop Sandvik Cone Crusher spare parts package, including main shaft assembly, eccentric sleeve, inner bushing, mantle, concave and frame wear parts, covering all core rotary and wearing aftermarket cone crusher parts for Sandvik crushing equipment overhaul replacement.
Compatibility
Precision forged and CNC machined to match original Sandvik CH440 cone crusher dimension standard. All aftermarket main shaft assembly and matched Sandvik crusher parts are manufactured following OEM dimensional tolerance, supporting direct mounting without onsite cutting or modification to original Sandvik cone crusher spare parts.
Quality Control
Every finished CH440 main shaft assembly is inspected by chemical composition test, hardness detection, ultrasonic flaw check and full-size calibration. Strict quality supervision effectively boosts anti-fatigue performance and prolongs service lifespan of all Sandvik aftermarket cone crusher parts and crusher parts in rugged mine operating environments.
