Premium Quality Materials & Construction
- Main Seals (Blue Rings): Manufactured from high-performance imported Polyurethane (PU), offering exceptional tensile strength and wear resistance to endure high-frequency friction.
- O-Rings & Auxiliary Seals: Constructed from Nitrile Rubber (NBR) and Fluoroelastomer (FKM) to resist high temperatures and aging, performing reliably in harsh hydraulic environments.
- Back-up/Guide Rings (White Rings): Made of reinforced PTFE or Nylon to provide outstanding anti-extrusion properties, preventing seal deformation under extreme pressure.
- OEM-Level Precision Match: Manufactured using high-precision molds with strict dimensional tolerance control. This ensures a 100% perfect fit for the R200W-7 steering cylinder, allowing for a hassle-free, direct replacement installation.
- Extended Equipment Lifespan: Effectively seals out external dust, dirt, sand, and moisture, protecting the piston rod from scoring and scratches. This significantly reduces maintenance frequency and minimizes costly downtime.
