  • Page 6 Caution 1. Air leakage due to removal of the seal belt Mechanical joint type rodless cylinders may have a temporary external air leakage in some operating conditions due to the product construction when negative pressure is generated inside the cylinder with external force, inertial force, or etc.
  • Page 7 2. Operation and Mounting 2-1. Air supply The compressed air supplied to the cylinder should be filtered by SMC AF series air filter and regulated to the specified set pressure by SMC AR series regulator. Warning 1. Use clean air. Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salts or corrosive gases etc., as this can cause damage or malfunction.
  • Page 8 7. Avoid storing the product in high temperature and/or humid conditions. Rust may be generated or the sealing parts may be deteriorated in such an environment. 8. This product is not designed for use in clean rooms. 9. Do not mount the product in locations where it is exposed to radiant heat. 10.

  • Page 14 Caution 1. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting. 2. Performance using at constant speed Mechanical joint type rodless cylinder has a larger fluctuation in speed compared to the rod air cylinder due to its construction.
  • Page 15 Warning 1. Do not operate the product when the cushion capacity that exceeds the allowable value. Operation while exceeding the allowable cushion capacity may damage the cylinder and may cause injury or damage to equipment. If operation requires a larger cushion capacity, install an external absorber to prevent impact to the cylinder body.
  • Page 16 5. The cylinder, eguipment and/or workpieces might be destroyed if the table collides the end of the stroke without being buffered properly by the shock absorber. See below for the number of cycles that are possible within the catalog usage range (model selection graph range), and check the operating conditions periodically, adjusting or replacing the shock absorber when necessary.
  • Page 17 2-9-1. Using switch spacer 1. Hold the switch spacer then push it into the groove. (Fig. 15) 2. Ensure that the switch spacer fits in the correct position. 3. After checking the detecting position, tighten the mounting screw (M2.5) to fix the auto switch. Fig.15 Note) For the tightening of the mounting screws, use a precision screwdriver with a handle diameter of approximately 5 to 6 mm.
  • Page 18 Caution 1. For the handling of the auto switch, refer to the Operation Manual of the auto switch. 2. Do not let objects drop onto the product or apply with an excessive impact to the product when handling. 3. Avoid wiring that applies repeated bending stress and/or tensile force on the lead wire.
