Advanced material with a denser structure!
Wear rings have the task to guide precisely the piston rod of a hydraulic-cylinder and to absorb the existing lateral forces. There must be no metallic contact between the sliding parts, i.e. with the counter surface.
Krütex 102 is distinguished for careful characteristics of the gliding surface and high absorption ability for defilement particles. The laminate material consists of cotton woven fabric, impregnated with phenolic-resin according to DIN 7735 – Hgw 2086.
Our manufacturing process envolves the complete line, starting with phenolic-resign plus woven fabric, resulting in finished wear-rings, bushes or bearings, with excellent tolerances. This procedure includes prepreg-fabrication, tube-production on modern winding machines and the use of CNC revolving automatons, each step accompanied by careful quality control. For this reason, we are able to react fast and flexible to special requests of our clients with respect to dimensions.
Standard range of dimensions and tolerances:
Inside diameter: 15 mm – 500 mm Width: from 3 mm
Wall thickness: 1,5 mm – 25 mm Tolerances: 0,03 – 0,08 mm
