Hydraulic Oil Seal MPS/MPI/U + S Reinforced Main Oil Seal Excavator Bulldozer Seal Ring
Product Overview
Hydraulic Star-shaped U-ring MPS Combination Seal | Advanced U + S Sealing System
The Hydraulic Star-shaped U-ring MPS Combination U + S Seal is a precision sealing component developed specifically for high-pressure hydraulic systems. It innovatively integrates the bidirectional sealing capability of the U-shaped seal structure with the elastic compensation advantages of the star-shaped S-ring, forming a core design of 'dual sealing + elastic self-adaptation'.
Manufactured from imported high-quality elastomeric materials through precise molding and secondary vulcanization processes, this seal maintains excellent performance under extreme pressure, temperature fluctuations, and complex medium environments. It effectively addresses industry challenges such as wear, leakage, and short service life of traditional sealing components.
U-shaped main seal layer: Optimized lip angle design automatically adheres to sealing surface under pressure, forming bidirectional sealing barrier that withstands up to 40MPa working pressure
S-shaped star elastic ring: Embedded inside U-shaped structure, provides continuous elastic compensating force, adapts to minor deformations and wear, reduces friction coefficient and power loss
Selection of high-end materials for complex working conditions
Main material composed of PU + NBR with wear-resistant and high-pressure resistant properties
Excellent tear resistance (≥15kN/m), compression set resistance (≤20%), and temperature resistance range (-30℃~120℃)
Precision manufacturing process with stable and reliable quality
Formed using CNC precision molds with dimensional tolerance controlled within ±0.02mm
Extensive testing including 24-hour high-temperature aging, 100,000-cycle pressure test, and medium immersion test
Product pass rate reaches 99.8% with service life 3~5 times longer than traditional seals
