For many of the mechanical system of linear reciprocating motion of the supporting role, or transmission shaft support and cooperation, and linear bearing.
用于各种有直线往复运动的机械系统中，起支撑或传动的作用，常与轴支撑、直线轴承配合使用。
The magnetic mechanism and the driving device composed of the overlapped permanent magnet not only can be used for transferring the linear reciprocating motion but also the rotary motion.
用这种重叠式永久磁铁所构成的磁力机构和传动装置，既可以用来传递直线往复运动，也可以用来传递旋转运动。
