▁prevent ▁wear ▁and ▁hydro static ▁types ▁may ▁be ▁completely ▁imm obile ▁when ▁de press ur ised . ▁Over all ▁power ▁consumption ▁is ▁typically ▁higher ▁compared ▁to ▁ball ▁bear ings . ▁ ▁Power ▁consumption ▁and ▁st iff ness ▁or ▁d amp ing ▁greatly ▁vary ▁with ▁temperature , ▁which ▁comp licates ▁the ▁design ▁and ▁operation ▁of ▁a ▁fluid ▁bearing ▁in ▁wide ▁temperature ▁range ▁situations . ▁ ▁Many ▁types ▁of ▁fluid ▁bear ings ▁can ▁cat ast roph ically ▁se ize ▁under ▁shock ▁situations ▁or ▁unexpected ▁loss ▁of ▁supply ▁pressure . ▁Ball ▁bear ings ▁d eter ior ate ▁more ▁gradually ▁and ▁provide ▁ac oust ic ▁sympt oms . ▁ ▁Like ▁c age ▁frequency ▁v ibration ▁in ▁a ▁ball ▁bearing , ▁the ▁half ▁frequency ▁wh irl ▁is ▁a ▁bearing ▁inst ability ▁that ▁generates ▁ecc ent ric ▁pre cess ion ▁which ▁can ▁lead ▁to ▁poor ▁performance ▁and ▁reduced ▁life . ▁ ▁Fl uid ▁leak age ; ▁keeping ▁fluid ▁in ▁the ▁bearing ▁can ▁be ▁a ▁challenge ▁for ▁liquid ▁types , ▁vac u um ▁recovery ▁and ▁fil tr ation ▁can ▁be ▁needed ▁in ▁some ▁situations . ▁ ▁O il ▁fluid ▁bear ings ▁are ▁imp ract ical ▁in ▁environments ▁where ▁oil ▁leak age ▁can ▁be ▁destruct ive ▁or ▁where ▁maintenance ▁is ▁not ▁econom ical . ▁ ▁Fl uid ▁bearing ▁" p ads " ▁often ▁have ▁to ▁be ▁used ▁in ▁pairs ▁or ▁tri ples ▁to ▁avoid ▁the ▁bearing ▁til ting ▁and ▁losing ▁the ▁fluid ▁from ▁one ▁side . ▁ ▁Un like ▁gre as eless ▁mechanical ▁bear ings , ▁fluid ▁bear ings ▁cannot ▁operate
