SKF PWY 80X90X6.3X9 Zaskočno poliuretansko posnemalno tesnilo z enim tesnilnim robom, dodatnim statičnim tesnilnim robom in radialnimi rebri na notranjem premeru

Hydraulic wiper seals prevent contaminants from entering a cylinder assembly and hydraulic system. PWY seals are polyurethane snap-in wiper seals. They have a single-lip design, with an additional outwardly directed sealing lip to provide better static sealing ability in the housing. Radial ridges prevent the wiper seal from getting a distorted shape in the housing which could lead to reduced wiping efficiency.
