Description
Symmetrical U-cup seal for reciprocating hydraulic applications. Function: Seals piston or rod against cylinder barrel/rod; bidirectional sealing capability. Installation: Defined by installation space dimensions (AD x ID x L). Materials: Available in NBR, TPU, PTFE, hard fabric, fabric-reinforced NBR (see material tables). Temperature range: Material dependent (e.g., NBR -40°C to +100°C; PTFE -100°C to +250°C). Pressure: Suited for moderately demanding hydraulic pressures (exact range not specified). Surface finish: Groove base and flanks must meet specified roughness; mating surfaces Ra ≤ 0.3 µm recommended. Certifications: Meets common industrial standards; not approved for automotive, aerospace or safety-critical applications. Warehouse DIN ISO 9001 & 14001 certified. Options: Custom compounds, kitting, technical services (drawing prep, radial force measurement).
Possible Applications
This symmetrical U-cup seal is primarily utilized in double-acting hydraulic cylinders found in agricultural machinery, such as tractor front loaders and harvesting equipment, where it effectively seals reciprocating rods and pistons. It is also widely integrated into material handling systems, including forklift mast cylinders and hydraulic scissor lifts, to maintain system pressure during lifting cycles. In factory automation, maintenance teams install these seals in hydraulic clamping cylinders on machine tools and assembly lines. The symmetrical profile makes it an ideal choice for general industrial maintenance and repair operations because a single seal design can service both rod and piston applications, reducing warehouse inventory complexity.
