Original kvalitetsdel. Må ikke forveksles med rimeligere alternativer. Engelsk beskrivelse : "This is the workhorse of the Mini gearbox. This double roller bearing supports the shaft where it transmits the power to the wheels. When this bearing goes, the mainshaft loses it support and as a result can take out the rest of the box in a hurry. False economy to ignore this bearing when doing a rebuild and you need to fit a genuine RHP full cage bearing and not a cheap replacement."
