Installation and usage points
Installation between machine hoods, side doors, guard plates, or structural components, serving as a limiter, support, and anti-rebound function.
The pins/bushings at both ends require lubrication to avoid dry friction and abnormal noise.
Inspect the rod body for bending and cracks, and check the holes at both ends for enlargement and wear.
Replace the rod if bending, deformation, or abnormal noise is observed to prevent support failure that could lead to component falling or interference.
