■Amount of travel
  The catalog drawing size is the state of travel 0mm, and taking this as reference, the distance moved in the left and right directions is the amount of travel.

■Load capacity
 is the force in N that the positioning stage can withstand when the center of gravity of the workpiece is in the center of the positioning stage. If used in excess of the load capacity, the positioning stage may not move properly or get stuck. Refer to the values of "Horizontal" and "Vertical" for the load resistance for horizontal and vertical installation respectively. Note that when the linear motion positioning stage is installed vertically or upside down, the accuracy may be less than the value indicated in the catalog.

■Straightness
  The maximum offset relative to the ideal axis of movement (the line connecting the start and end points is shown as the red line in the figure below. The black line is the actual trajectory of movement.) when the positioning stage moves at full stroke. Detection method: Place the micrometer on the positioning stage, with the pointer held against the reference block, let the positioning stage move at full stroke, and measure its maximum displacement, which is the straightness.

■Installation Method of X-Axis Positioning Stage
   When mounting the positioning stage to the base, basically it is mounted by moving the positioning stage surface. Refer to the following diagram.

The above diagram is for demonstration purpose only. Refer to each catalog or 3D data for detailed shapes and specifications of the positioning stage.

■Mounting Posture

Horizontal, inverted, side-mounted horizontal or side-mounted vertical installation options are available. Other installation methods should be given more attention.
Load capacity and accuracy will change greatly depending on the mounting posture.
○：Same as horizontal load capacity.
△：About 1/3 of the horizontal load capacity is the approximate standard, if the catalog contains the vertical load capacity, it should be given priority.

■Vertical Use of X-Axis Positioning Stage
  When using the X-axis positioning stage vertically, pay attention to the feed direction, which should not be in the same direction as gravity.
  When using a micrometer knob type positioning stage, note that the positioning stage is reset by extension spring. If the force applied is greater than the spring load, the positioning stage surface may fall. For such occasions, alterations can be used as a solution.

Wrong Usage Method	Correct Usage Method
(Usually) If the force applied exceeds the tensile load of the spring, the positioning stage surface may slip off because it cannot support the weight.	After selecting the alteration of the micrometer knob position change, the positioning stage surface does not fall even when used vertically.

Avoid applying loads that exceed the load carrying range in the vertical direction.

Mechanism name: Cotton swab glue application position adjustment

■Operating temperature and environment
  Recommended operating environment: 10～50℃, 20～70%RH (no condensation)
  Accuracy assurance environment: 22±5℃, 20～70％RH (no condensation)

■Guiding mechanism
  This positioning stage adopts crossed roller guide as the guiding mechanism. Please refill the lubricant at the right time according to the usage conditions to prevent the life of crossed roller guide from being shortened due to the decrease of lubricant and aging.

■Clamping mechanism
  ①The clamping mechanism of the positioning stage is fixed by the frictional force generated by the fastening screw, so when the applied external force exceeds the frictional force of the clamping mechanism section, it will cause the positioning stage to move. The user should take appropriate measures to avoid movement of the positioning stage surface during use. If clamping reinforcement is required, disc clamping or opposite clamping can be selected.
  ②The holding force is the value of the force that keeps the positioning stage surface from moving in the clamped condition. Since the maximum holding force varies with the tightening torque, please ensure a sufficiently large safety factor when designing.

■Feed mechanism
  The shape of a positioning stage with a micrometer knob installed as shown in the figure below is generally called the standard type. Free selection is possible by combining the installation space, mounting posture, and operation method. However, due to the structure of the product, there are some models where the installation position of the micrometer knob cannot be changed. For details, refer to the [Alteration] at the bottom of each product page.


■Flatness of the mounting surface
The upper and lower positioning stage surface may be deformed due to the different flatness of its mounting surface. Deformation of the positioning stage surface may result in gaps, looseness due to failure to obtain the specified preload, or poor sliding due to excessive preload. Therefore, it is recommended that the flatness of the mounting surface be kept at about 5 microns.
