Set Plate Ring Description

The Swing Motor Set Plate Ring (Part No. YNF16545) is a precision-machined spacer used in the SG04 swing motor assembly for excavators. Known as a “介子” in Chinese hydraulic repair terminology, this component is positioned between the set plate and piston group to maintain correct spacing, motion clearance, and pressure distribution. YNF Machinery’s set plate ring is engineered with tight dimensional tolerances to avoid misalignment and premature wear in hydraulic swing systems. It is a critical part for excavator swing motor rebuilders and parts distributors ensuring performance consistency.

FAQs

Why Is the Set Plate Ring Important?
Also referred to as an “intermediary ring” or “swing motor spacer,” this part keeps the internal components like the set plate, piston group, and valve plate properly aligned. Without it, component clash, imbalance, or oil leakage may occur. YNF’s SG04 set plate ring YNF16545 is built to ensure lasting integrity under rotational stress in excavator swing motor systems.
