NMY Rod Seal
Overview
The NMY rod seal is a compact, two-part sealing system designed for high-performance hydraulic and pneumatic cylinders. It combines excellent sealing efficiency with strong contamination exclusion in a space-saving design.
Key Features
Two-Component Design: Consists of a PTFE-based primary sealing ring and an elastomeric loading element (typically NBR).
Integrated Functions: Provides dynamic sealing, static sealing, and built-in scraper action in one unit.
Asymmetric Lip Profile: Features a low-friction primary sealing lip and an aggressive secondary wiper lip.
Pressure-Activated: System pressure energizes the seal via the elastomer, improving sealing force as pressure rises.
Function
Seals system pressure during rod movement.
Excludes dust, dirt, and moisture from entering the cylinder.
Maintains a thin lubricating film for low friction and long life.
Typical Applications
Mobile and industrial hydraulic cylinders
High-pressure applications
Applications requiring reliable performance with minimal leakage
Advantages
Low friction and smooth operation
Excellent resistance to extrusion
Compact axial space requirement
Easy installation as a pre-assembled unit
Installation Notes
Install with the primary lip facing the pressure side and the wiper lip facing outward.
Requires a standard rectangular gland groove.
Hard chrome-plated rod with fine surface finish is recommended.
In summary, the NMY rod seal is a reliable, integrated sealing solution ideal for demanding rod sealing applications where performance, compactness, and durability are critical.
