A rubber-metal part is part of the suspension design, not a generic replacement rubber.
Its geometry and compound influence load transfer, stiffness, vibration and service life.
Before: replacement is matched mainly by shape and dimensions.
After: the component is selected or developed from its actual suspension function.
The product is only useful when it fits the real railway job.
CBP brings the vehicle requirement and Indonesian project context to TMS, then manages qualification, testing, supply and lifecycle replacement planning.
