Huilian SB81 Membrane — Reliable Excavator Breaker Seal
Product Overview
What is the SB81 Membrane?
The SB81 membrane from Huilian is a precision-made rubber diaphragm used in hydraulic excavator breakers. It acts as a critical seal inside the breaker hammer, keeping hydraulic oil and gas separated while ensuring smooth impact transfer. Built for tough jobsite conditions, the SB81 membrane delivers consistent sealing performance and long service life.
Key Features
Durability and Materials
Manufactured from high-grade elastomer compounds, the SB81 membrane resists wear, heat, and oil aging. This reduces the frequency of maintenance and lowers total operating costs.
Precision Fit
Each membrane is crafted to tight dimensional tolerances to ensure a reliable fit with OEM-style breaker components. This minimizes leaks and maintains stable breaker performance.
Easy Installation
SB81 is designed for straightforward replacement. Technicians can install the membrane quickly, reducing downtime and keeping equipment working longer between services.
Applications
The SB81 membrane is suitable for a wide range of hydraulic breakers used on excavators in construction, demolition, quarrying, and mining. It is compatible with many mainstream breaker models and ideal for field repairs and scheduled maintenance.
