DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of pneumatic oil seal in China. If you're going to buy bulk pneumatic oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.
Pneumatic equipment relies on compressed air as power source, yet its rotating assemblies must rely on lubricants to cut friction and abrasion. The Seal delivers dual protection: it seals grease and lubricating oil inside rotary structures, and stops external dust, water vapor and grit from invading the assembly. Correctly matched oil seals greatly lift the running stability of pneumatic rotary parts and extend their overall service life.
Selection Guide
Multiple key parameters need confirmation before ordering to pick the proper pneumatic oil seal:
- Rotary shaft rotation speed
- Continuous working temperature range
- Matching type of lubricating medium
- On-site working environment (dry, dusty, humid etc.) DEDE supplies standard NBR pneumatic oil seals applicable to most general industrial pneumatic equipment. Custom rubber materials are available upon special working condition demands.
Typical Applications
● Pneumatic drive power units
● Screw & piston air compressors
● Rotary pneumatic actuators
● Full sets of industrial automation machinery
● All kinds of pneumatic rotary transmission systems
Product Details
Precision flexible sealing lip
Adopting micron-level trimming technology, the thin and uniform lip fits the rotating shaft adaptively, preventing micro oil leakage and air leakage. The ultra-low friction design ensures flexible operation of light-load pneumatic equipment without extra running resistance.
01
Reinforced embedded metal frame
The integrated metal frame enhances overall structural rigidity, maintaining stable coaxiality after installation. It prevents sealing offset and loosening caused by frequent pneumatic start-stop, improving overall sealing stability and structural durability.
02
Oil and aging resistant surface treatment
The sealing surface is specially treated to resist oil erosion, oxidation and hardening. It adapts to humid and dusty workshop environments, avoiding cracking and aging failure in long-term pneumatic lubrication working conditions.
03
Constant-pressure spring locking structure
The precision tension spring adaptively adjusts locking force according to equipment operation status. It tightly locks lubricating oil in static state and maintains low-resistance fitting in operating state, balancing sealing performance and operation flexibility.
04
High-precision tolerance groove adaptation
Strict dimensional tolerance complies with pneumatic equipment installation standards. The outer ring fits closely without gaps, preventing impurity penetration and oil mist leakage. It features high installation tolerance and supports fast manual assembly and replacement.
