1 Centering Unit Alignment and positioning of transferred workpieces Contributes to space saving on conveyor lines Heavy workpieces can now be aligned and positioned with small cylinders, resulting in compact conveyor lines. Table Max. allowable load weight: 2205 lbs (1000 kg) (MACM10) Workpieces can be moved in any direction: forward/backward, right/left, at an angle, and even rotated (360 ). Ball bearings allow for smooth operation. Table centering accuracy ±1 mm or less Right/left (Workpiece not loaded) Angled Rotation Forward/backward Table center movable range Max. ø100 mm (MACM10-50) Table center ø (Stroke) 3 types of table material can be selected. Stainless steel Ultra high molecular weight polyethylene Cast nylon For lock/unlock confirmation External photo sensor mountable Select from lock port side or opposite side of port installation. Built-in air locking mechanism Table can be held in any position. External photo sensor Locking port Unlocking port MACM Series NP-E16-22A

4 Centering Unit MACM Series Working Principle Neutral (Centering) condition Movable condition <Application Examples> wbearing espring for returning to center Movement qtable Body Bearing cage rcenter shaft When a force is applied to q the table in the lateral direction, w the bearing slides. When the bearing slides, e the spring for returning to center also expands and contracts. When the force in the lateral direction is released, r the center shaft is returned to the neutral position by e the spring for returning to center. Lock Mechanism Unlocked condition The table becomes free when unlocked. Locked condition The table is locked in place when locked. tbearing holder plate tbearing holder plate Clearance rcenter shaft qtable wbearing rcenter shaft Locking port Unlocking port Locking port Unlocking port ypiston for locking ypiston for locking When air is supplied from the locking port, y the piston for locking descends and pushes r the center shaft down. When r the center shaft lowers, t the bearing holder plate is pressed, and the table is locked. When air is supplied from the unlocking port, y the piston for locking ascends and releases the lock. 3

Use the product within the movable range. 2. Use the product within the allowable load weight. 3. Load workpieces within the load range. 4. Load workpieces within the allowable inclination range. 5. Do not use the product in applications where excessive external force or impact force is applied to it. Improper handling includes the following: Applying impact on the side of the table to move it to full stroke Operating Precautions Continuously moving the table in a circle while the table is at a full stroke Repeating reciprocation of the table at full stroke Holding the body and swinging the table 6. Prevent over strokes. 7. Secure the table in place when transporting the product or the equipment it is mounted on. 8. This is not a clean room series product. 4
