Product Description

Product Description

KDAS compact seal,also called DAS,DDAS,KDAS is a double-acting seal and compact piston oil seal.

DAS piston seal set include a rubber seal,two split support rings and two split bearings, located either side of the seal. The profile seal ring seals in both the static and dynamic range whilst the backup rings prevent extrusion into the sealing gap. The function of the guide rings is to guide the piston in the cylinder tube and to absorb transverse forces. The design provides a compact seal and guide combination for a closed or split installation groove. It is a combination seals used in hydraulic applications as well as some heavy industries.

Product Parameters

 

With 5 parts design our KDAS compact seals are used as piston seal for double acting cylinders at maximum 400 bar.          
          

KDAS has a NBR ring, having 3 sealing lips, in the middle; 2 polyester elastomer back-up rings used for decreasing permissible gap in both sides; 2 POM rings as guide besides them.  As seen in the design, sealing operation is carried out by NBR ring.

Oil seals solution

Rotary shaft seals

Oil seals, grease seals and dust seals help prevent lubricant leakage by retaining the fluid within the cylinder and at the same time, protecting it from intrusion of harmful external elements.
Oil seals are divided into three main categories according to their design: rubber outside diameter, metal outside diameter and metal outside diameter with a metallic cage inside.
