Description

Product Name: Step Washer – Aftermarket  Cone Crusher Spare Part For Sandvik
Material:High-strength forged alloy steel, medium carbon alloy steel with quenching & tempering heat treatment; customized material hardness and thickness can be arranged per customer’s working condition requirement.
Function:
The step washer is a core anti-loosening Sandvik cone crusher spare part directly fitted onto the outer step surface of main shaft, positioned between main shaft shoulder and head nut inside upgraded Sandvik CH series cone crusher. It relies on unique stepped contour to lock the axial position of head nut firmly, bearing alternating vibration and torque load during continuous ore crushing operation instead of main shaft. As indispensable Sandvik crusher spare parts, it stops head nut from spontaneous loose rotation and slipping displacement, avoids abnormal gap change of main shaft assembly, prevents surface scratch and thread damage on expensive main shaft and head nut, and stabilizes running precision of matched Sandvik Cone crusher parts inside main shaft locking system.
