NB - Miniature Slide Table
6Pages

The ball raceway grooves of the bed and table are processed through simultaneous precision machining resulting in minimal processing errors, and bringing about extremely smooth, precision linear movement. The table height of the SYBS type is 3.2 ~ 4.5mm and the width is 6 ~ 12mm. This compact envelope when compared with conventional slide tables helps to realize the miniaturization of machinery and equipment. > The SYBS type slide table is constructed from only stainless steel materials. This allows for use in corrosive or high temperature applications. The SYBS is a perfect component for vacuum or clean room type environments. > Since the rolling ball elements do not re-circulate, the frictional resistance will not vary significantly resulting in smooth operation reliable high precision. Additionally, the caged balls greatly reduce the contact noise of the rolling elements bringing about a low-noise operation. > Figure H-27 Structure of SYBS Type Slide Table tableball cagestopper bedball H-52 NB's miniature slide table incorporates a unique integrated ball cage between the table and bed. All components have been produced with high precision machining technologies. >
