Features & Benefits

  • Flexible sealing edge supports continued conformity during extended downtime
  • Retention profile helps stabilize alignment during fast hub reassembly
  • Internal rigidity limits deflection during sudden weight-transfer events
  • Installation footprint aids mechanics working with limited hub clearance

Stemco Drive Axle Wheel Oil Seal 

The Stemco Drive Axle Wheel Oil Seal protects lubricant inside the hub while shielding bearings from contamination during long-haul or local route operation. Sized for a 4.625" spindle OD and a 6" bore diameter, the seal establishes a secure interface between rotating and stationary components. The 0.981" width allows stable seating without crowding adjacent parts, and the construction helps sustain integrity through varied temperature cycles and axle loads. Its design supports consistent lubrication retention, reducing the likelihood of premature wear. This Stemco 373-0243 is suited for wheel-end assemblies that operate through extensive vibration and heat variations.
