DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of drum shaft seal in China. If you're going to buy bulk drum shaft seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.
Rotary drum equipment runs continuously with long-term contact to water, laundry detergent and chemical cleaning agents. Ordinary general oil seals will quickly swell, harden or leak when exposed to aqueous cleaning media. Our Drum Shaft Seal adopts a low-friction optimized sealing lip structure matched with integrated metal skeleton. The tight lip-shaft fit forms a durable waterproof barrier, isolating mixed water-detergent medium outside the bearing chamber and avoiding premature bearing corrosion and abrasion caused by liquid penetration. Two elastomer grades NBR and FKM are supplied to match household front-load washing machines and heavy-duty industrial drum cleaning equipment separately, maintaining consistent sealing performance under long-hour continuous rotation.
Material Matching Options
NBR Nitrile Rubber Shaft Seal
Cost-effective standard grade for household front-load washing machines. Good resistance to daily laundry detergents and cold & warm washing water; working temperature range -35℃ ~ +100℃, perfect for domestic appliance mass production and maintenance replacement.
FKM Fluoroelastomer Shaft Seal
Premium high-temperature & chemical resistant grade for industrial washers and heavy-duty drum cleaning equipment. Stable within -20℃ ~ +160℃, tolerates high-temperature hot water, concentrated alkaline cleaning agents and corrosive industrial detergents.
Typical Applications
Household front-load washing machines
Commercial industrial washing machines
Rotary drum type industrial cleaning equipment
All kinds of mechanical equipment built with rotating drum transmission systems
Product Advantages
Adaptive drum-shaped structure with higher tolerance
The exclusive curved drum design compensates long shaft deflection and eccentricity, eliminating partial wear and intermittent leakage caused by shaft swinging, which cannot be solved by ordinary flat-lip seals.
Strong deformation resistance for long shaft operation
Optimized for continuous swinging and slight deformation of long roller shafts, the lip always fits the shaft surface tightly without gap leakage or dry wear.
Enhanced dust and water protection
The widened outer protective flange blocks dust, mud and splash water, suitable for dusty, humid and harsh working environments.
Stable sealing under variable speed and load
The constant-pressure spring and flexible curved structure automatically adjust fitting status, preventing low-speed oil splashing and high-speed overheating for consistent dynamic sealing performance.
High compatibility for roller equipment replacement
Customized for drum and roller shaft equipment, it can directly replace old special roller seals without shaft or hole modification for easy maintenance and upgrading.
Excellent aging and wear resistance
The curved structure disperses local stress, reducing friction loss and aging cracking, achieving longer service life than standard ordinary oil seals.
