MYR-Type Piston Rod Seal

MYR Series: Multi-Year Rod Seal System

Product Overview

MYR (Multi-Year) series represents a paradigm shift in sealing longevity, engineered to deliver 5-10 years of continuous, maintenance-free operation in standard industrial applications. Through predictive material science and time-compensating design, MYR seals fundamentally redefine service intervals and reliability expectations.

Longevity Engineering

1. Chrono-Stable Material System

  • Temporal Reinforcement: Fiber alignment optimized for progressive load distribution over years

  • Aging Compensation: Built-in material expansion counters natural elastomer shrinkage

  • UV/Ozone Resistant Core: Multi-layer protection against environmental degradation

2. Time-Adaptive Geometry

  • Progressive Lip Angle: Self-adjusting contact profile maintains optimal pressure across lifespan

  • Wear-Compensating Design: Material migration from non-contact areas to wear zones

  • Memory Polymer Elements: Return to original geometry after temporary deformations
