Heavy Machinery & Earthmoving
High loads, impact forces, continuous vibration. bondura® expanding pins keep heavy machinery running — from excavators and mining loaders to forestry equipment and tower cranes.
Built for machines that never stop working
Heavy machinery pin joints are exposed to wear, deformation and fretting, compounded by humidity, ice and relentless operating cycles. Left unaddressed, this leads to frequent maintenance, unplanned downtime and shortened equipment life.
bondura® Expanding Pin Technology eliminates play at the source: 360° wedge force and 180° load distribution within the pivot joint removes the need for line boring and significantly extends service intervals. Certified and approved for replacing existing pins.
Construction
bondura® expanding pins are installed in the positions most exposed to heavy loads: heavy loaders, excavators, trucks and cranes.
The technology is used both in new equipment and as a direct replacement for worn pins in existing machinery, restoring precision and extending equipment life without major intervention.
Forestry
Forestry equipment runs hard across every step of the value chain, from harvesting machinery in the field to processing plants handling wood chips, saw and paper.
bondura® expanding pins are installed in wood chopping tools, handling equipment and production line machinery, reducing the maintenance burden at every stage.
Mining and quarrying
In mining and quarrying, a few hours of unplanned downtime translates directly to lost revenue. The consequence is higher still in underground operations, where the complexity of repairs and logistics compounds every failure.
bondura® expanding pins are installed in front loaders, crushers and rock blasting equipment, keeping critical joints precise under the most extreme loads and vibrations.
