Combi seals, also known as combination seals, are innovative sealing solutions that integrate multiple sealing functions into a single compact unit. The COMBI Oil seal is an inseparable entity connected by a metal frame, consisting of standard SC/TC/DC shaft seals and polyurethane contamination-resistant deflectors. It is particularly valued for its robust ability to form a pollution-resistant barrier. The material and design of the polyurethane component create a barrier against external impurities, making the combination seal highly reliable.

 

Combi seals find applications in a wide range of industries and machinery, including automotive, aerospace, industrial equipment, hydraulic systems, and more. They are used in various rotating shaft applications such as pumps, motors, gearboxes, and rotary equipment where reliable sealing is critical for performance and longevity.

 

Heavy-duty wheel seals and agricultural equipment seals are categorized as AP type and ST type. They are primarily used in heavily polluted environments such as agricultural machinery, construction machinery, mining equipment, trucks, buses, and more. In comparison to the TC type, the special internal lubrication design ensures close contact with the rotating shaft seals and bearing components, effectively preventing external dirt. The specifically designed multiple lips inside the seal enable it to achieve this function. The multi-lip design externally prevents dirt and grease leakage, while high-quality grease (butter) internally prevents mud and water immersion.

 

Combi seals are designed to provide a combination of sealing functions, including:

Radial shaft sealing: Preventing leakage along the rotating shaft.
Axial sealing: Sealing against fluid or contaminants from entering or exiting along the axis of the shaft.
Dust exclusion: Keeping dust, dirt, and other contaminants away from the sealing area.
Grease retention: Retaining lubricating grease within the system to ensure proper lubrication of moving parts.

 

Components of a combi seal include:

Elastomeric sealing lips: These provide the primary sealing function against the shaft and prevent fluid leakage.
Spring elements: Used to maintain radial or axial pressure on the sealing lips, ensuring proper contact with the shaft and effective sealing.
Auxiliary sealing features: Additional lips, barriers, or labyrinth designs may be incorporated to enhance sealing performance and prevent contamination ingress.
Reinforcing elements: Metal or composite reinforcements may be included to provide structural support and stability to the seal.

 

Proper installation is crucial to ensure optimal performance of combi seals. Regular inspection and maintenance are also recommended to detect any signs of wear, damage, or leakage and to replace the seals as needed to maintain system integrity.

NNK Combi Oil Seal Manufacturer

Combi Oil Seal

COMBI Oil Seals composed of more than two Oil Seal parts can be called COMBI Oil Seals. Most of the simple combined Oil Seals are made of steel and oil-resistant rubber. Developed for extreme wear applications, the Oil Seal and dust seal are combined in one metal housing, ready to use.

 

You will get efficient and thoughtful service from xtnbk.

Structure

This type of COMBI Oil Seal is an Oil Seal composed of a rubber lip, a metal skeleton and a spring ring (or more). It has inner and outer skeleton to clamp the rubber lip. Usually the COMBI Oil Seal also has a baffle to prevent the spring from coming out.

 

Spring loaded sealing lip

Additional dust lip to prevent dirt ingress and provide protection under extreme operating conditions 
Primarily used in all highly contaminated applications, such as off-road vehicle axles 
In cases where rotational and translational movements are superimposed, it is best to use a snap-on seal instead.

 

Material

NBR, FKM, FPM, PTFE.

 

Type

With dust lip (i.e.double Lip Oil Seal) or without Dust Lip (i.e.single Lip Oil Seal)

 

Feature

COMBI Oil Seals can always take advantage of the characteristics of various sealing materials to maximize their advantages. COMBI is an Oil Seal for reciprocating motion. Most Oil Seals at the joints of moving parts are made of materials with low coefficient of friction, low friction, less wear, smooth movement and long life. This material (PTFE) is self-lubricating and does not easily adhere to metal.

 

Advantages

Long service life
High resistance to dirt ingress due to optimal positioning of the sealing and dust lips
Performance in relation to external dirt
High resistance to dirt from the outside. Suitable for sludge protection.

 

Applications

Agricultural machinery 
Suitable for extreme dirt entry and critical applications 
Agricultural vehicles and general industrial drives
