Note 2: Distance within which the table can move when it returns to origin, etc. Make sure any workpiece mounted on the table does not interfere with the workpieces and equipment, etc., around the table.
Note 3: Position after return to origin.
Note 4: Values within [ ] are for when the direction of return to origin has been changed.
Note 5: When using the body bottom positioning pin holes, do not use the housing B bottom pin hole.

Notes

*Do not apply load in excess of the specification limits. Select a suitable actuator by work load and allowable moment. If the product is used outside of the specification limits, the unbalanced load applied to the guide will be excessive and have adverse effects, such as creating play on the guide, degrading accuracy and shortening the lifespan of the product.
*Do not use the product in applications where excessive external force or impact force is applied to it. Doing so can cause the product to malfunction.
*Refer to the SMC catalog for product information other than what is detailed above.
*The product image is a representative image only.
