DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of tcn oil seal in China. If you're going to buy bulk tcn oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.
Different from standard single-lip TC oil seals, TCN adopts an optimized dual-lip integrated structure with reinforced metal skeleton and full rubber-coated outer diameter.
Inner spring-loaded primary sealing lip
Stainless steel garter spring delivers lasting radial clamping force, maintaining tight shaft contact to prevent lubricant leakage under slight internal pressure; special lip curve resists lip flipping caused by medium thrust.
Outer auxiliary dust lip
Sits on the air side to intercept dust, mud, sand, splashing cooling water and abrasive particles before they reach the main sealing zone, avoiding premature lip abrasion and seal failure. The full rubber outer OD fits housing bores perfectly, absorbing minor thermal expansion and assembly tolerance, suitable for long-cycle continuous rotation in dusty workshops and outdoor machinery environments. DEDE supplies NBR and FKM two mainstream rubber materials to match normal temperature and high-temperature working
