Manual Rotary Stages Running-In Installation Type

MISUMI E-RPG series manual rotary stages is an economy series stage. It can be used as a positioning stage for simple position adjustment. The body is made of aluminum alloy to achieve light weight; the surface is black anodized. Prices have been significantly reduced due to local production in China and improved machining process.

Type	Material	Surface Treatment	Movement (mm)	Load Capacity (N)	Lateral Misalignment
E-RPG	Aluminum Alloy	Black Anodized	Rough Adjustment 360° Fine Adjustment±5°	9.8~78.4	Within 30 μm

■Amount of travel
The catalog drawing size is the state of travel 0°, and taking this as reference, the degrees rotated 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.

■Lateral misalignment
refers to the amount of deviation from the rotation center.

Code	NR

The mounting dimensions of micrometer knob and clamp are different from standard products. Please confirm the detailed dimensions according to CAD data.

Feature 1: The body is made of aluminum alloy to achieve light weight
Feature 2: Low price is achieved by simplifying the structure and improving the machining process.
Feature 3: Through holes are set to enable cable routing, positioning of rotary polarization elements, etc.
Feature 4: By improving the clamping mechanism, the holding force of the positioning stage is greater than that of the standard type clamping mechanism.

■Installation Method of Rotary Stage
When mounting the stage to the base, basically it is mounted by moving the 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.
Precautions for Surface Precision of Mounting Part
 When the components mounted on the bottom or top of the positioning stage are not flat enough, the product may fail to operate with intended performance. (Reference standard of flatness: within 10μm)

■Mounting posture of rotary stage
Load capacity and accuracy will change greatly due to its mounting posture. Please use the following characteristics table as rough reference for the usability in a particular mounting posture.
The rotary stage cannot be mounted inversely, or its performance may change greatly.
It can be side-mounted, but can be used only when the load is applied in the direction of micrometer knob; it cannot be used for applications where no load is applied to the micrometer knob (see the diagram below).
