Description
The Alltrux ATX-S429 Drive Axle Inner Wheel Bearing Set replaces industry standard SET429TRB and is engineered for heavy-duty commercial truck rear drive axles equipped with ConMet PreSet and PreSet Plus hub systems. This premium tapered roller bearing assembly is equivalent to cone 594A PS and cup 592A PS and is designed for inner wheel end positions requiring high load capacity, precise alignment, and long service life.
Bearing sets designed for PreSet hub systems differ from traditional adjustable wheel bearings by providing controlled preload and simplified installation without manual adjustment. This design reduces installation errors, minimizes friction, and helps improve wheel end reliability and fuel efficiency in long-haul and fleet applications.
Manufactured to handle demanding radial and axial loads, this bearing set features an approximate 3.75 inch bore and 6.00 inch outer diameter, making it suitable for modern heavy-duty drive axle hub assemblies used on trucks such as Freightliner and other OEM platforms utilizing ConMet PreSet technology. Proper installation following hub manufacturer guidelines is essential to ensure optimal wheel end performance and durability.
