NKS type

NKS type xipuli' piston (hole) seal is a special piston (hole) seal developed on the basis of YA type of standard shaft-hole dual-purpose seal introduced from the former Soviet Union, aiming at the requirements of domestic forging hydraulic machinery, agricultural machinery industry and other industries for the use of hydraulic sealing systems without leakage and long life under the condition that the original groove size remains unchanged.

Main advantages:
● Good wear resistance
● Impact resistance
● Compression deformation is small.
● Improved sealing performance under zero pressure
● Good sealing performance and long service life
● Easy installation

Scope of application:
Working pressure ≤ 30Mpa
Working temperature: -30- 110 ℃
Surface speed: ≤ 0.8 m/s
Mainly used for forging hydraulic press, rubber vulcanizer, as well as all kinds of small cross-section requirements of the hydraulic cylinder or cylinder on the piston hole seals.
Installation: This type of seal should have axial clearance. In order to avoid damage to the sealing lip, do not install the seal in. Pull on the sharp edge.
Material: XA-1092 is a nano-modified high-performance polyurethane sealing material independently developed by xipuli. The invention patent number is 201110257111.7. Compared with other polyurethane materials on the market, the main advantages are improved heat resistance, good aging resistance and hydrolysis resistance, small compression deformation and long service life. Can process 2.5 meters in diameter of the crystal.
