COMPATIBILITY:

Mineraloils, water soluble & water glycol fluids. APPLICATION: Lightto medium duty hydraulic cylinders Canalso be used in conjuction with SS Style rod seals for heavy duty applications. MiningEquipment. Hydraulicprops & presses.

DETAILS:

The SUNRUB type UB seal is a flexible seal suited for sealing piston rod. Theadditional o’ring profile at the bottom provides as a back-up to the mainsealing lip, providing lubrication, abrasion resistance & remains unaffectedwith varying pressures. Also available in nitrile (NBR) upto 160 BAR besidesPolyurethane for 300 BAR. Due to excellent wear resistance properties ofpolyurethane the life expected is 3 times that of NBR.

FEATURES:

Simpleinstallation. An O’ring profile at bottom improves sealing & serves as a good back-up tothe main sealing lip. It wipes off small traces of oil that passes the sealinglip with every stroke.
