Platform Cylinder A highly rigid and highly accurate slide table integrated with an actuator. Two styles of guide rod bearings to accommodate your application Slide bearing—for heavy loads Ball bushing bearing—for highly accurate and smooth operation Auto switches can be installed. A shock absorber can be installed (option). Can be mounted on two sides. Mounting from upper side Mounting from bottom side Guide of high rigidity Adjustment bolt with bumper is standard. Performs the function of a cushion and adjusts the stroke 5mm on each side, or 10mm for both sides. For moving and transporting workpieces. For moving the receptacle for workpieces used in stamping or press-fitting processes. For using as a P&P unit in combination with other actuators. CXTM (Slide bearing) CXTL (Ball bushing bearing) Allowable Table static weight displacement (kg) (mm) Allowable static weight (kg) Note 1) "Table displacement" is the amount of deflection of the guide rod that occurs when a maximum load weight is placed on the maximum stroke table while the table is at the center of the stroke (the amount of looseness Note 2) Allowable static load is not included). Note 2) An "allowable stationary weight" is the allowable amount of stationary weight that can be applied vertically to the workpiece mounting surface of the table while the table is at the stroke end. Note 1) Table displacement Variations Bearing Slide Ball bushing ·····Standard stroke ·····Long stroke

Weight CXTM (Slide bearing) Stroke (mm) CXTL (Ball bushing bearing) Stroke (mm) Note 1) Factors in parentheses are weight of movable parts (weight of movable parts of the cylinder is included.) Note 2) The weight indicated above does not include a shock absorber. Precautions for Handling Operation q Make sure not to apply to the slide block a load that exceeds the value that has been calculated in the selection procedure. w Operate the cylinder securing it by its plates, not by securing it by its slide block. e The clearance between the slide block and the plate at the stroke end is...
