DLI
GDK
4016931000
DLI is a dust-proof and oil - scraping double - acting dust-proof seal. The bilip metal skeleton dustproof ring can prevent the entry of dust, dirt, sand and metal chips, prevent scratch and protect the piston rod metal surface, prolong the working life of sealing parts and have the function of scraping oil.
Material : NBR/PU+SPCC
Max pressure: ≤32MPA
Temp range: -35~+120ºC
Max Speed: ≤2m/s
DLI dust seal is used to prevent dust, dirt, sand, and metal chips from entering the hydraulic cylinder. Due to reducing the intrusion of external contaminants into the sliding element creates a risk of scratches. Besides, the special design of the lip of the dust ring can achieve an excellent dustproof effect. The DKB type has a strong wear resistance, a small permanent deformation, and is characterized by the use of proven external mechanical shock resistance. The diameter of the seal groove is not only tightly fitted to the metal, but also the dust seal can be securely mounted at an appropriate position in the axially formed groove.
