Writer discusses also the characteristic of silicon nitrid ceramic materials,and chooses this ceramic bearing used in the bottom of the reactor above. 論述了氮化硅陶瓷材料的特點(diǎn)，選擇了氮化硅陶瓷軸承作為有機硅室溫膠攪拌釜底軸承并進(jìn)行了相應設計。
Oil may be forced out through the timing cover and rear-main bearing oil seals. 機油會(huì )從正時(shí)齒輪蓋和后主軸承油封處壓出。
The front cover exactly matches this shape and also has a raised circular area that fits into a matching countersunk area of the block in front of the main bearing. 封面完全匹配這個(gè)形狀和也提出了圓形區域，可以成為一個(gè)匹配埋頭面積塊前面的主軸承。
