Excavators and loaders repeatedly cycle through mud, dust and abrasive material while carrying heavy loads. Standard seals may lose their dirt barrier early, leading to contaminated bearings and repeat teardown. This long-life Integrated COMBI Seal combines lubricant retention with multi-stage external exclusion to help protect rotating assemblies and reduce seal-related downtime on machines working in harsh construction environments.
Problem solved: Helps excavators and loaders avoid repeat seal replacement caused by mud-driven wear and contamination.
