Excavators

Keep your vital machinery operational for longer with our hydraulic seal replacement kits for excavators including boom, arm, bucket and level cylinder kits.

Superior Cylinder Seal Kits for Excavators Booms, Arms and Buckets

Excavators endure rigorous tasks such as digging, lifting and loading, which can lead to hydraulic system challenges. Fluid contamination can damage seals and shafts, creating a path that leads to leakage and seal failure.

Implementing a robust hydraulic sealing solution from Chesterton Customseal can enhance cylinder reliability by extending operational hours between failures and reducing downtime.

To safeguard your excavators and minimise operational costs, Chesterton Customseal offers high-performance, turnkey cylinder repair kits engineered to excel in the most challenging environments.

Our field specialists collaborate closely with customers to assess specific requirements and deliver tailored sealing solutions.

With decades of engineering expertise in the mining industry, our team is dedicated to developing innovative solutions that address the most demanding sealing challenges.

Seal Kits for Hitachi Excavators

Chesterton Customseal’s proprietary thermoset polymer technologies offer high abrasion and cut. Built for power and precision, Hitachi excavators operate in some of the toughest conditions. But over time, seals wear down, leading to hydraulic inefficiencies and potential breakdowns.

Our aftermarket seal kits are compatible with Hitachi excavator models EX1100, EX1200, EX1800, EX1900, EX2500, EX3600 and EX5500. These premium seal kits are designed for a perfect fit, ensuring smooth operation and reduced maintenance costs.

CASE STUDY

Sealing Solution Prevents Costly Excavator Downtime

A mine was experiencing leakage of worn, scored shafts in the boom cylinder of an excavator, causing an unplanned shutdown and production loss. Upon inspection, the OEM rubber wiper was found ineffective, leading to scoring of the piston rod.

Our specialist recommended a cylinder upgrade installed on site – including a 21K split wiper with a 11K split stacked set. This significantly improved reliability and postponed the capital repair of a large diameter, heavy duty hydraulic cylinder.
