Specifications

The 42673XT Scotseal XT from SKF delivers robust sealing for heavy duty drive axles, especially popular in Mack 44,000 lb drive applications. With a unitized, one-piece design, it includes four sealing lips and multiple unitizer rings to preserve lip integrity during installation. Its outer lip is constructed from HNBRX for high temperature stability and low drag, while the inner lip uses EPDM for reliable contact with the spindle. Because it’s hand-installable, the risk of damaging the seal during fitting is minimized. It’s compatible with modern synthetic and semi-synthetic lubricants, helping fleets reduce maintenance intervals. Available interchange charts show equivalence with many Stemco, National, and Meritor seals. This seal supports fleet uptime, lowers cost per mile, and is ideal for demanding on-road drive axle service.
