Generation 1 hub bearings feature a separable double-row angular contact ball bearing design that is pressed into the wheel hub during assembly. This classic configuration requires precise preload setting on the assembly line and is serviceable with standard bearing maintenance procedures. Gen 1 bearings remain popular for compact and economy passenger cars, rear wheel applications, and light-duty trailers where cost-effective, proven technology is preferred over integrated hub units.
