Are there any standard sizes for the imperial ball screw or is it customizable based on need?

滚珠丝杠螺母中的滚珠应该是要装满的，这样可以保证螺母在旋转时滚珠可以顺畅地滚动，从而减少摩擦和磨损，提高螺母的使用寿命。如果滚珠没有装满，会导致螺母旋转时摩擦增大，容易出现卡滞或者滑动不平稳的现象。因此，在安装滚珠丝杠螺母时应该确保滚珠装满。

Is the imperial ball screw commonly used in certain industries or applications?

Ball Screw Specification Imperial Units Lead (inches/rev): This is the distance the nut will travel axially in one revolution of the screw. Example: 0.5 inches/rev. Diameter (inches): This is the diameter of the screw shaft. Example: 1 inch. Pitch (inches): This is the distance between adjacent threads on the screw. Example: 0.2 inches. Max Load (lbs): This is the maximum load that the ball screw can handle without failing. Example: 500 lbs. Dynamic Load Rating (lbs): This is the load that the ball screw can handle for 1 million revolutions with a 90% reliability. Example: 1000 lbs. Accuracy (inches/ft): This is the maximum deviation from the desired position over a distance of one foot. Example: 0.001 inches/ft.
