Description
Symmetrical U-cup seal (type N21) for hydraulic cylinders. Same functional characteristics as N05 but with different profile geometry. Installation space dimensions: Defined by AD, ID, L. Materials & temp.: As per material overview (NBR, TPU, PTFE, etc.). Application: Moderately demanding hydraulic systems. Certifications & services: Identical to N05.
Possible Applications
This symmetrical U-cup seal is deployed in moderately demanding hydraulic actuation systems found across mobile machinery and industrial automation equipment. Typical implementations include agricultural loaders, municipal utility vehicles, and standard hydraulic presses where reciprocating rod and piston sealing requires reliable fluid containment under moderate pressure cycles. Because the geometry provides equal sealing lips on both the inner and outer diameters, it functions effectively in both internal and external sealing configurations within standard cylinder housings. Maintenance technicians frequently utilize this profile during the overhaul of hydraulic cylinders in material handling equipment and factory automation actuators due to its versatile interchangeability across diverse elastomer and thermoplastic material grades.
