Skeleton Radial Shaft Oil Seal 168×188/190×30/32 Heavy Truck Crankshaft Transmission Wheel Hub Seal For FH12 FH16 FM12 FMX Replacement Parts
Purpose-built for the demanding drivetrain sealing requirements of FH12, FH16, FM12 and FMX heavy truck series, this 168×188/190×30/32 skeleton radial shaft oil seal delivers reliable crankshaft, transmission input/output shaft and wheel hub oil retention across long-haul and severe-duty operating cycles. The rigid carbon steel skeleton provides structural stability under the high radial loads and thermal cycling typical of heavy truck powertrains, while the dual-lip configuration—an inner FKM sealing lip for hot gear oil resistance and an outer NBR dust lip for road debris exclusion—forms a comprehensive contamination barrier. For fleet maintenance operations managing high-mileage trucks, this seal offers the consistent sealing reliability needed to prevent roadside breakdowns, oil loss and premature bearing wear between scheduled service intervals.

- High-strength steel skeleton + wear-resistant rubber lip
- Optimized for heavy truck crankshaft and transmission shaft sealing under sustained high-speed rotation and thermal cycling
- Dual-lip configuration: FKM inner lip resists hot gear oil degradation, NBR outer lip blocks road dust, water spray and debris
- Reinforced outer metal case withstands press-fit installation forces without deformation, ensuring consistent housing bore contact
- Extended seal life reduces unscheduled roadside service events and protects adjacent bearings from contamination-related failure
