While there are identical bearing sizes used in wheel hubs and suspension pivots, installing MAX bearings in wheel hubs, or fast-spinning Enduro hub bearings in suspension pivots is unadvisable. To optimize performance and reduce drag, Enduro hub bearings include bearing ball retainer rings, low viscosity speed grease a light contact, dual-lip LLB seals. The make-up of a high-performance hub bearing is a serious mismatch for the demands encountered in modern MTB suspension designs.Conversely, Enduro MAX full-compliment suspension bearings only rotate a few degrees and are engineered to withstand 1000's of high-load, jarring impacts. MAX bearings do not include retaining rings which provides space for additional balls (increasing load capacity 35-40%), extra thick, high-pressure grease and full-contact, double-lip LLU seals. These design features are a perfect match for suspension pivot bearings, but way too burly and sloth-y for bicycle hubs. Also, to assemble a full-complement radial bearing, it requires that a fill slot be ground into the inner and outer races to allow the additional bearings to be inserted into the races, which makes the bearing design not particularly well suited to withstand the axial loads found in hubs and BBs.Visit Enduro Bearing Basics to learn more.
