3349963 XCMG GR2605 motor grader spring washer
Introduction
3349963 spring lock washer is a commonly used anti-loosening element in the fastening system of construction machinery. It is mainly used at bolt and nut connections, providing continuous tension through its own elastic deformation to prevent thread loosening caused by vibration and shock, ensuring reliable connections. Made of elastic steel with uniform opening and stable elasticity, it is suitable for key parts such as gearboxes, frames and traveling mechanisms.
