GNY Packings

Sakagami GNY rod packings are engineered with high wear-resistant RN919 material for exceptional durability. Featuring a larger cross-sectional area than SKY-packings, they support extended operation times and superior sealing. GNY packings maintain stable performance even under significantly eccentric rod action, making them ideal for demanding hydraulic applications.
