A152 U-ring rod seal has symmetrical lips, an energising O-ring and a POM extrusion ring. It is designed to be used for heavy duty hydraulic cylinders in rod applications. It offers exceptionally high performance in working conditions where high pressure and shock loads are present, provides lower friction, dry rod sealing and increased seal stability of the twin lip design.

A152 can be used safely for construction machinery, moving and loading platforms, forklifts, agricultural machinery, injection moulding equipment, mining and steel industry, and any heavy working condition cylnders, etc.

Its is recommended to be used in combination with minimum one guiding element such as A251, A254, A255, A256, depending on the working conditions.

A301 piston seals are produced by machining technique from a special compound of bronze-filled PTFE, combined with an O-ring used as an energizing ring. A301 can be used safely at high sliding speeds due to its low friction force, which is among one of the essential properties of PTFE. By changing the O-ring material, A301 can be used for type of oils different from mineral-base hydraulic oils.

Material: PTFE + bronze + NBR70
