Description
Generic N and NI series rod seals (asymmetrical U-cup). Installation: In closed grooves, minimum rod diameter d_min depends on profile width S (table page 10): S=4→d_min25, S=5→30, S=6→40, S=7.5→50, S=10→80, S=12.5→100, S=15→120. For d<25 mm, axially open installation recommended. Function: Rod sealing, pressure on one side.
Possible Applications
The N and NI series asymmetrical U-cups are engineered for hydraulic cylinders operating under single-acting pressure conditions where reliable rod sealing is critical to prevent fluid leakage. These seals are frequently integrated into mobile hydraulic systems, such as agricultural machinery, construction excavators, and material handling equipment, where space constraints necessitate compact, robust sealing solutions. Because of their profile geometry, they are particularly effective in reciprocating motion applications found in industrial presses and hydraulic actuators where maintaining a consistent oil film is essential for reducing friction and wear. Their design ensures high performance in standard hydraulic circuits where the seal must withstand unidirectional pressure cycles while maintaining structural integrity within the gland.
