WRFAI split bearings are manufactured of an extremely abrasion-resistant and low-friction POM-PTFE Bronze compound. The excellent dry-running properties allow installation behind the primary rod seal. The WRFAI utilizes a scraper edge for integrated wiping function and contaminant removal. These are genuine Hunger® parts.
