Seal the Deal with Chesterton in mining is a tough gig that demands even tougher mining equipment.
Operating in harsh and remote environments, these big heavy-duty machines need regular maintenance due to stress, dust, dirt, and corrosion, all of which has huge impacts on reliability and uptime.
While a lot of attention focuses on the large parts and components of fluid power reciprocating equipment, rotary, and specialty equipment, smaller elements are also vital, with apparatus reliant on the performance of multiple internal seals.
Degraded seals can result in expensive equipment shutdowns, repair and replacement, environmental and safety issues, and unbudgeted extra labour costs.
To ensure equipment delivers peak performance for maximum productivity, polymer seal manufacturer Chesterton offers customised solutions that can enhance operations through increased reliability and performance whilst also bolstering the operational bottom line.
The Western Australia-based company produces high-performance elastomeric polymer seals for a wide range of hydraulic, pneumatic and rotary equipment, including hydraulic seals, rotary seals, spring energised seals and customised polymer seals.
Made from global OEM Chesterton’s raw material – AWC 860, these seals have high tolerance, quality and durability for abrasive environments, and are available in mining kits for a range of excavator brands, including Liebherr, Cat, Hitachi and Komatsu.
The company also has turnkey cylinder repair kits that match proprietary polymer technologies with unique seal geometries, to help improve the performance of off-road mining equipment.
The aftermarket hydraulic cylinder seal kits feature upgraded seals and components for longer service life, greater reliability, and improved performance.
The kits contain all the necessary seals and components in one box with one unique item number, eliminating the need to inventory multiple items.
