Why Use a High-Quality Ball Guide in Hydraulic Pumps?
A ball guide ensures stable piston motion within the cylinder block, minimizes deviation, and reduces wear caused by misalignment. Especially in excavators, where consistent fluid pressure and mechanical precision are essential, a worn ball guide can cause vibration and premature piston damage. YNF’s YNF16488 provides excellent durability, dimensional precision, and perfect fit with PCR-5B-30A pump sets.
