Roller screw ends can refer to two different things: 1. The ends of the roller screw itself: The roller screw is a type of screw that uses rollers instead of threads to convert rotary motion into linear motion. The ends of the roller screw refer to the two ends of the screw shaft, where the rollers are housed within the nut. These ends can be designed in different ways depending on the application, such as with flanges for mounting or with different types of seals. 2. The ends of the roller screw assembly: The roller screw assembly includes not only the screw shaft and nut, but also the motor, bearings, and other components. The ends of the assembly refer to the two ends where the roller screw is mounted and connected to other components, such as the motor or gearbox. These ends can also be designed in different ways depending on the application, such as with different types of couplings or mounting flanges., 总的来说，滚珠和滚珠丝杠都是机械传动中不可或缺的零部件，它们的应用范围广泛，具有重要的作用, 3.接着，绘制出SW滚珠丝杠的左、右两端的结构，包括轴承座、止动环、齿轮等零件的位置和尺寸, 2. 螺纹长度（L）：滚珠丝杠的螺纹部分的长度, 8. 更换润滑油：根据需要更换润滑油，注意不要过量，也不要过少,它的主要作用是将旋转运动转化为直线运动，具有精度高、负载大、寿命长等优点，被广泛应用于各种机械设备中，如数控机床、自动化生产线、航空航天等领域, 3.配备安全防护装置，保证操作人员的安全,滚珠丝杠螺母的标准长度根据不同的标准和规格而异, 5. 开始加工：按照制定的工艺流程，开始加工, 3. 滚珠丝杠选型还需要考虑丝杠的精度等级，以确保所需的运动精度
