Llinear Motion Ball Slide Unit is a linear bearing bearing rail unit assembled by the guide rail, LM shaft and the open mouth linear bearing installed in the box unit. Used for guiding, fixing machine parts, equipment, instruments, etc. In our daily life, the application is also very common, such as the slip of the sliding door, the train track and so on are the specific application of the guide rail. All components are standardized, so they can be used interchangeably, reducing costs and design time. Linear sliding unit support guide rails (SBS, TBS, SBR-S, TBR-S, SK, SHF). Throughout the stroke, the bearing rail provides stiffness as well as rigidity to the shaft, thus ensuring the performance of the device. It is a high precision and non-offset guide device that allows the system to run smoothly and achieve stiffness, thereby reducing costs and shortening.
