In dynamic mechanical systems where pressure, speed, and environmental factors converge, the choice of sealing technology directly affects system longevity and operational efficiency. The TCN high pressure oil seal series, developed and supplied by DEDE, is engineered to offer reliable sealing in high-pressure, high-speed rotary shaft applications, ensuring optimal performance even in the most rigorous industrial environments.
1. Design and Performance Features
The TCN series features a dual-lip
construction: the primary sealing lip prevents lubricant leakage under elevated
pressure, while the secondary lip acts as a dust barrier, shielding internal
components from external contaminants. This configuration enhances sealing
reliability in systems exposed to both internal pressure and external
debris.
2. TCN high pressure seals often incorporate:
· Nitrile Rubber (NBR) or Fluoroelastomer (FKM) for superior chemical resistance and thermal stability
· Carbon steel or stainless steel case reinforcement for added structural integrity
· Spring-loaded lips to maintain consistent radial pressure throughout shaft rotation
The TCN series is particularly known for its resistance to extrusion and deformation, even when exposed to fluctuating loads and aggressive operating media.
3. Application Suitability
TCN High Pressure Oil Seals are widely used in
rotating equipment operating in:
· Hydraulic motors and pumps
· Heavy-duty gearboxes
· Construction and mining machinery
· Energy generation systems (including wind turbines)
· Industrial automation and robotics
· Marine propulsion systems
· Off-road agricultural vehicles
· Compressors, actuators, and diesel engines
Given their robust sealing capability, TCN seals help reduce lubricant loss, avoid equipment contamination, and maintain mechanical efficiency across sectors such as industrial machinery, fluid power systems, rail transport, and renewable energy.
