Unique SEALS

•SJ Tech's sealing technology have been widely employed in extreme environments such as in agriculture, construction, forestry and mining.

•Our seals operate under wide range of pressure and temperature withstanding dust and moisture along with the corrosive greases and fluids inside and outside pneumatic & hydraulic cylinders.

MATERIALS

‘Our MATERIALS are extremely resistant to abrasion, and their low-friction properties proportionate ideal results for rotary solutions’.

Our purpose is to guarantee the machine's performance by providing a long-lasting sealing solution.

Low friction rotary seals are optimized for equipment that requires long periods of operation and consists of rotation and vibration that require lubrication. The rotary seal is made of an ultra-high molecular material and NBR material suitable for high pressure based on Engineering Plastic.

KNOW-HOW

Finite element analysis is conducted by applying a constant value according to the mechanical property value of the material.

In this process, the behavior and deformation characteristics of the SEAL and the contact surface pressure on the seal are checked when the seal is mounted on the cylinder and subjected to pressure.

At this point we can determine whether the generated stress value deviates from the material's intrinsic property value.

QUALITY

SJ Tech's SEALS are verified through deep analysis, prototyped and tested for the highest durability.

For the durability test of seals, we have test equipment similar to the structure that is actually mounted on cylinders, and SJ Tech is constantly testing  the quality level of the developed products.

The durability tester proceeds with a linear reciprocating motion similar to a hydraulic cylinder, and tests are conducted in accordance with the test standards for reciprocating seals for cylinders such as static leakage test, dynamic leakage, and low-temperature function test.
