In spite of the development of elastomeres they can not meet all demands which are made on sealing materials in the field of heavy and mobile hydraulic engineering. As a solution for these applications we are pleased to offer you the HECKER® seals made of fabric reinforced elastomeres.
The surface structure of the seals enables the deposit of lubricants and there for favours the neccesary formation of the lubricant film between the seal and the slide face. Further more due to the high extrusion stability, a bigger housing gab can be bridged with fabric seals as with seals made of pure elastomeres.
As materials Aramid- and cotton fabric with different mesh sizes and coatings are available.
