求翻譯：All ball bearings can withstand a certain amount of thrust, but if the thrust is sufficiently high to preclude the use of deep-groove bearing, an angular-contact bearing may be used. If the bearing is single-row, the thrust, of course, can be resisted in one direction only. Double-row angular-contact bearings allow thr是什么意思？ 待解決
