Product Overview

This heavy-duty accumulator diaphragm (piston cup seal) is specially developed for Inan Makina MTB85 hydraulic rock breakers, the core energy storage sealing component of breaker accumulator system. It completely isolates high-pressure nitrogen and hydraulic oil, solves common failures like nitrogen leakage, weak striking force, frequent nitrogen refilling and short service life of original diaphragm.

Adopted imported high-performance HNBR rubber with reinforced fiber layer, the diaphragm owns outstanding oil resistance, high temperature resistance, anti-fatigue and tear resistance. It fully matches OEM dimensional standard, restores full impact power of MTB85 breaker, greatly cut maintenance frequency under long-term heavy crushing operation.

Key Selling Points

  • 1. 100% Exact OEM Replacement. Fully dimensional matched with original MTB85 breaker diaphragm, consistent with OEM part numbers 45B0122A11 and MTB85-DIAPHRAGM. No trimming, no modification, direct plug-and-play installation.
  • 2. Premium Reinforced HNBR Raw Material. Core diaphragm body adds fiber reinforcing layer, excellent anti-fatigue stretch performance. Stable elastic performance under -35°C low temperature to 135°C high oil temperature, anti-aging, anti-swell from hydraulic oil.
  • 3. Zero Nitrogen Leakage & Stable Impact Force. Pass strict 110MPa high-frequency fatigue impact test. Effectively prevent nitrogen escaping, maintain stable accumulator energy storage, keep continuous strong striking force without power attenuation during long-time crushing.
  • 4. Ultra Long Service Life & Low Maintenance Cost. Resist frequent reciprocating deformation, avoid early tearing, cracking and bulging failure of ordinary rubber diaphragms. Reduce times of nitrogen filling and diaphragm replacement, lower machine downtime and overall operating cost.
  • 5. Strict Factory Full Inspection. Every diaphragm goes through air tightness, high pressure fatigue, high & low temperature aging tests before delivery, fully reach OEM quality standard, reliable for all-day heavy construction workload.
  • 6. Wide Application Scope. Perfect match for MTB85 hydraulic rock breakers equipped on various construction machinery:
  • 6–10 ton medium excavators
  • Small wheel loaders with breaker attachment
  • Municipal demolition engineering equipment
  • Road & bridge concrete crushing machinery
  • Mining secondary rock crushing equipment
  • Foundation excavation & old building demolition hydraulic hammer systems
