The unsung heroes of mining machinery

“Seals may seem insignificant compared to the scale of mining equipment,” said Mark, “but their failure can have enormous consequences.” He explained that even a low-cost seal failure could result in costly machine downtime, environmental damage, or significant repair expenses.

Hydraulic and rotary seals prevent the leakage of gases or liquids in mining equipment like haul trucks, dozers, and excavators. Mark highlighted how seals work in tandem with components such as rod wipers and wear bands to withstand extreme conditions, from abrasive contaminants to high pressures. “The right seal material can make all the difference,” he added, describing how Motion tailors seals to specific applications using materials like polyurethane, PTFE, and specialised thermoplastics.

Custom solutions for mining demands

A key focus of the webinar was Motion’s customisable seal kits for heavy mining equipment. Mark emphasised their flexibility to meet customer needs: “Unlike OEM kits, our solutions can be customised to include upgraded materials, additional components, or even redesigned seals to address unique challenges.”

Motion’s seal kits are particularly valuable for large-scale mining equipment. Case studies demonstrated their reliability, such as a field trial in Indonesia where Motion’s kits surpassed the 14,000-hour operational benchmark.

Tackling downtime with CNC precision

David introduced Motion’s Interseal division, which manufactures custom seals using advanced CNC machines. “This capability allows us to deliver seals tailored to the exact specifications of our customers, often in less than 24 hours for urgent breakdowns,” he said.

The team highlighted the advantages of machined seals over traditional moulded alternatives, including faster lead times, cost efficiency, and greater adaptability. David showcased an innovative solution for a century-old ball mill on a mining site, where a custom split seal resolved chronic leakage and downtime. “Eighteen months later, the seal is still running, and the customer hasn’t needed to use the spare set we provided,” he said.

Innovation driving sustainability

The webinar also underscored how seal innovations contribute to sustainability. Upgraded materials increase equipment efficiency and reduce waste, while robust designs minimise the environmental risks of fluid leaks. “By preventing failures, we’re not just saving costs—we’re reducing environmental harm and enhancing safety,” said Mark.
