The WDH TCN oil seal is a high-performance double-lip rotary shaft seal engineered to handle high-pressure and high-speed rotational applications. Its robust sealing structure and dust lip design ensure superior oil retention while preventing the ingress of dirt, mud, and other contaminants — even under demanding working conditions.
Double-lip design – Inner lip for oil retention, outer lip for dirt and dust exclusion
Durable materials – Available in NBR (Nitrile) or FKM (Viton®) for optimal resistance to wear, heat, and oil
Spring-loaded sealing lip – Ensures consistent radial contact and reliable sealing performance
High dust resistance – Ideal for harsh working environments
Wide size range – Customizable to fit various shaft diameters and housing bores
Agricultural machinery (tractors, harvesters, rice transplanters)
Industrial gearboxes and pumps
Construction and mining equipment
Automotive and heavy truck axles
Marine propulsion and power systems
