Description
KNA series piston seal for semi-enclosed installation spaces. Minimum mountable size: For KNA44 in semi-enclosed groove: d > 45 mm (rod diameter reference). Segment height of semi-enclosed installation: 0.9 mm (from table page 11). Dimensions: Not fully specified; series depends on L-dimension. Application: Hydraulic cylinders with limited axial access.
Possible Applications
The KNA44 piston seal is specifically engineered for hydraulic systems where restricted axial access prevents the use of standard, open-groove sealing components. This design is ideal for compact hydraulic cylinders found in mobile construction machinery, such as mini-excavators and hydraulic steering actuators, where space-saving configurations are critical for assembly. By facilitating installation in semi-enclosed grooves, this seal streamlines maintenance processes in industrial presses and hydraulic clamping units that require frequent component replacement without full disassembly of the cylinder head. Its asymmetrical geometry ensures reliable pressure containment in these space-constrained environments, effectively preventing fluid bypass in high-cycle hydraulic applications.
