China Industrial High Quality TCN High Pressure Oil Seal Durable NQKSF Seal

　　As industrial hydraulic and heavy-duty equipment reach higher pressure
ratings, conventional oil seals are increasingly pushed beyond their design
limits. The TCN High‑Pressure Oil Seal Series, developed by NQKSF (ShanFeng),
provides a robust sealing solution engineered for high‑pressure environments,
protecting equipment and minimizing maintenance cost.

　　Engineering Challenges in High‑Pressure Environments

　　High‑pressure systems face multiple simultaneous challenges:

　　Frequent pressure spikes common in hydraulic cylinders and actuators

　　Rapid temperature variations that strain standard elastomers

　　Dust, dirt, and fluid contamination accelerating seal wear and leakage

　　The TCN series addresses these through its advanced structural design and
material selection, significantly enhancing reliability.

　　Product Features

　　Cloth‑reinforced skeleton for enhanced resistance to pressure deformation,
maintaining integrity under up to 70 MPa transient loads

　　Dual‑lip or tri‑lip geometry—main lip for oil sealing, secondary lips
for dust and fluid exclusion

　　High-performance elastomer compounds (NBR, FKM, PTFE) tailored for
temperature, chemical resistance, and fluid compatibility

　　Precision molding and tight shaft interface fit minimizing leakage and
friction

　　Optimized for longevity in hydraulic machinery, wind turbines, agricultural
equipment, and metalworking applications

　　Recommended Applications

　　Hydraulic pumps, cylinders, and motors in industrial and mobile systems

　　Gearboxes and actuators in construction machinery

　　Wind turbine pitch and yaw mechanisms

　　Mining and metallurgy hydraulic platforms

　　Agricultural machinery and heavy transport equipment
