The Alltrux ATX-S430 Drive Axle Outer Wheel Bearing Set replaces industry standard SET430TRB and is engineered for heavy-duty commercial truck rear drive axles equipped with ConMet PreSet and PreSet Plus hub systems. This tapered roller bearing assembly is equivalent to cone 580 and cup 572 and is designed for outer wheel end positions requiring high load capacity, precise alignment, and long service life in demanding fleet and vocational applications.

Bearing sets designed for PreSet hub systems provide controlled preload and simplified installation without manual adjustment, helping reduce installation errors and improve wheel end reliability. The outer drive axle bearing plays a critical role in supporting radial and axial loads while maintaining smooth hub rotation and proper load distribution under heavy freight and long-haul operating conditions.

Manufactured from high-quality hardened steel for durability in severe service environments, this bearing set is suitable for modern heavy-duty truck drive axle hub assemblies using ConMet PreSet technology. It is commonly used across various commercial vehicle platforms and is ideal for fleet maintenance, axle rebuilds, and preventive wheel end service programs.
