H K C Urethane Ultra-Seal RodSeal
A D Hydro-Line’s Ultra-Seal RodSeal provides much longerwear life than conventional rod seals. Special urethaneformulation allows superiorresistance to abrasion, tear- ing and extrusion. The bal-anced radial cross-sectionaldesign with back-beveled sealing lips provides excel-lent low pressure sealability.Higher pressures energizethe sealing lips increasing the contact stress profileand giving the added seal-ing needed at increased pressures.

Key Features

Sculptured FloatingCushions
L Unitized Rod CartridgeConstruction Self-centering cushions aresculptured to allow thecylinder driving force and load to be absorbed gradu-ally and smoothly over theentire cushion length main- taining near constant pres-sure. Refer to pages 20 and21 to determine your spe- cific cushion requirements. LAN5 •The unitized constructioncontains all cartridgeseals in one assembly•Standard removableretainer allows cartridge removal with hex wrenchwithout loosening the tierods•See Page 5 for excep-tions Pneumatic cylinders incorpo-rate all AN5 features and arealso permanently lubricated at assembly by filling the pis- ton and rod seals “V” groovewith molybdenum disulfidegrease.
