The permissible tilting angle is given for each spherical plain bearing and rod end in the product tables. 每種球面滑動軸承和桿端裝置的允許傾斜角在產品表中一一列明。
Spherical plain bearings and rod ends with the sliding contact surface combination of steel-on-steel and steel-on-bronze require maintenance. 採用鋼與鋼和鋼與銅滑動接觸面組合的球面滑動軸承和桿端關節軸承需要進行維護。
Because of the oilless self-lubrication characteristic in ceramic, the bearing may overcome lubrication problems in an ultra-high vacuum environment. 因陶瓷材料獨具的無油自潤滑特性，故在超高真空環境中，可克服普通軸承無法實現潤滑的難題。
