Each shafting comprises:
轴系包含
—
Intermediate shaft
中间轴
—
Propeller shaft (oil lubricated)
螺旋桨轴（油润滑）
—
Fixed pitch propeller
定距桨
The propeller is to be fit on aft end of propeller shaft by wet type keyless fitting mode.
螺旋桨通过湿式无键连接安装在螺旋桨轴后端
The propeller shafts will be arranged for inward withdrawal.
螺旋桨轴设计成向里面抽出

The stern tube bearings are to be of white-metal type. The stern tube seal will be of oil lubricated simplex compact type.
尾管轴承为白合金，尾管密封为油润滑新波莱克紧密式密封
The design of shafting will conform to the requirement of ABS, without ice Class notation
轴系设计满足ABS要求，没有冰区加强
