Rod Seal (U-Cup asymmetrical, inner sealing), SNI30, SNI30, Freudenberg Sealing Technologies (Dichtomatik)

Possible Applications

This asymmetrical U-cup rod seal is primarily integrated into medium-duty hydraulic cylinders operating within agricultural machinery like tractors and front loaders, as well as construction equipment such as mini-excavators and skid steers. It is highly suited for the reciprocating piston rods of material handling systems, including forklift mast cylinders and scissor lifts, where reliable fluid containment is critical during lifting cycles. The inner-sealing asymmetrical lip design ensures optimal contact pressure against the dynamic rod surface, effectively preventing hydraulic oil bypass under fluctuating operating pressures. Additionally, its robust sealing profile makes it a dependable choice for pneumatic and hydraulic actuators in factory automation assembly lines, where it protects against external contaminants while maintaining system pressure.
