A single sealing edge can be vulnerable when mud, sand and dirt arrive continuously at the shaft. This multi-lip Integrated COMBI Seal creates successive barriers so external contamination must pass multiple defenses before reaching the primary oil-sealing zone. The structure helps protect lubricant, bearings and shaft surfaces in construction, mining, agricultural and other abrasive environments where dependable exclusion is essential.
Problem solved: Creates multiple contamination barriers where a single lip is not enough against mud, sand and dirt.
