speed ▁applications , ▁aer ost atic ▁bear ings ▁are ▁required ▁for ▁load ▁bearing ▁at ▁low ▁speed . ▁Both ▁types ▁require ▁highly ▁finished ▁surfaces ▁and ▁precise ▁manufact uring . ▁ ▁Ex amples ▁Air ▁hockey ▁is ▁a ▁game ▁based ▁on ▁an ▁aer ost atic ▁bearing ▁which ▁susp ends ▁the ▁pu ck ▁and ▁players ' ▁p add les ▁to ▁provide ▁low ▁fr iction ▁and ▁thus ▁sust ain ▁high ▁pu ck ▁spe eds . ▁The ▁bearing ▁uses ▁a ▁flat ▁plane ▁with ▁periodic ▁or ific es ▁which ▁deliver ▁air ▁just ▁over ▁ambient ▁pressure . ▁The ▁pu ck ▁and ▁p add les ▁rest ▁on ▁air . ▁ ▁Another ▁example ▁of ▁a ▁fluid ▁bearing ▁is ▁ice ▁sk ating . ▁Ice ▁sk ates ▁form ▁a ▁hyd rod ynamic ▁fluid ▁bearing ▁where ▁the ▁sk ate ▁and ▁ice ▁are ▁separated ▁by ▁a ▁layer ▁of ▁water ▁caused ▁by ▁entropy ▁( former ly ▁thought ▁to ▁be ▁caused ▁by ▁pressure - indu ced ▁mel ting ; ▁see ▁ice ▁sk ating ▁for ▁details .) ▁ ▁Mich ell / K ings bury ▁til ting - pad ▁fluid ▁bear ings ▁ ▁Mich ell / K ings bury ▁fluid ▁dynamic ▁til ting - pad ▁bear ings ▁were ▁invent ed ▁independently ▁and ▁almost ▁simultaneously ▁by ▁both ▁British - born ▁Australian , ▁Anthony ▁George ▁M ald on ▁Mich ell ▁and ▁American ▁trib ologist ▁Albert ▁Kings bury . ▁Both ▁designs ▁were ▁near - ident ical ▁except ▁for ▁differences ▁in ▁the ▁approach ▁used ▁for ▁pivot ing ▁the ▁p ads . ▁Mich ell ▁mathemat ically ▁derived ▁the ▁pressure ▁distribution ▁where ▁a ▁span - wise ▁line
