Product Information
Agricultural “AP” Seal
NAK Agricultural “AP” SEAL is designed for use in heavy contaminated
applications such as agricultural machinery, construction and mining
equipment, track driven vehicles, etc. It is ideal for use where oil or grease
must be held in contact with rotary shaft and bearing assemblies, while at the
same time sealing against external contaminants is required. With the
exceptional design of a unitized seal body and multiple lips and bumpers, the
NAK AP Seal is the ultimate dirt excluder. Custom designs can be worked out
and NAK will ensure that the seal is made to the exact specification.

Product Description
AP Seal, the Ultimate Dirt Excluder for Heavy Duty and Heavy
Contaminated Applications
NAK AP Seal is created for heavy-duty applications especially where environmental
and operating conditions are very harsh. The traditional lip seal (such as TC) that
consists of a spring loaded radial sealing lip and a static dust lip often falls short in
heavy duty and at the same time heavy contaminated applications. In many cases
the failure is caused by the penetration of mud and water at the radial lip. NAK AP
Seal resolves this problem by providing the optimal protection against mud, water and
other contaminants through a variety of design features.
Outer Protective Improved Seal
Faceplate Geometry
Multiple Lips & High-Quality Water
Bumpers Resistant Grease
Shaft Protective Strengthened
Sleeve Sealing Lips
Features
Improved seal geometric design including rubberized OD and ID for easy
installation and replacement in the field
Outer faceplate for protection against external contaminants and internal oil
and grease leakage
Multiple sealing lips which can be varied to suit required sealing purposes
Sleeve to protect the shaft from wear, especially when the roughness of the
shaft is larger than 1.0 Ra
Strengthened sealing lips and several bumper lips to give better sealing
Water resistant grease to ensure pre-lubrication and offer better reliability
during installation and replacement

Technical Information
Advanced Technologies to Ensure the Design Efficiency and
Accuracy of the AP Seal
In the creation of the AP Seal, NAK uses whole new design concepts and
advanced technologies to give to the AP Seal many superior benefits which
are not available in the traditional lip seal.
To ensure the efficiency and accuracy of the design of the AP Seal, NAK uses
advanced computer aided technologies such as Seal FEA and Seal CAE.
The systems are developed by NAK specifically for the purpose of seal design.
In addition, to verify the function and quality of the AP Seal, lab testing and
field testing are conducted prior to production launch so that we know the seal
is fit for the intended end application.
The excellent performance of NAK AP Seals has been verified in both NAK lab
testing and field testing conducted in collaboration with key customers.
