Feature of Liebherr PR732BL Dozer Track Roller

-Advanced Sealing System

Equipped with triple-labyrinth seals combined with heavy-duty lip seals, this roller effectively excludes abrasive materials in challenging environments. The special-grade rubber compounds maintain flexibility in extreme temperatures, while the optimized grease chamber design ensures continuous lubrication, extending service intervals and component lifespan.

– Enhanced Load Distribution

Through finite element analysis (FEA) optimized design, the roller body distributes ground contact pressure evenly across its entire surface. The reinforced rib structure provides exceptional impact resistance when operating over rocky terrain, while maintaining an optimal weight-to-strength ratio for improved fuel efficiency and reduced ground pressure.

-Precision Machined Surfaces

All wearing surfaces undergo CNC grinding to achieve precise dimensional tolerances and superior surface finish. The journal surfaces are honed to exact specifications to ensure perfect bearing fit, while the flange running surfaces are finish-machined to minimize friction and prevent track link interference during operation.
