TN = plastic insurance aircraft, allowing operation temperature: 120 ¡æ
continuously, 150 ¡æ temporarily, 180 ¡æ and short-term. 1) In the case of
lubricating grease to allow the listed numerical value of 60%.
+ There are stalls circle, no oil hole and groove, such as the need for hole
and slot, the required increase in the bearing code ASR1. |
