Metal seal structure with low sliding resistance enables to cover the range of a driving speed and an output control, which were not available with the general cylinder. Minimal sliding resistance allows low pressure actuation at 0.005 MPa. . Contact SMC regarding vacuum applications. Long service life of 10,000 km or 100 million full cycles.
Low friction
Lateral load resistance
Low pressure actuation
Long service life
Low and Uniform speed actuation Smooth, uniform speed actuation ranges as low as 0.3 mm/s. Low sliding resistance and high stability allow force control as low as 0.05 N. (Based on cylinder piston area x pressure accuracy) No increased sliding resistance after periods of non-operation. Lateral load resistance is increased by built-in ball bushing. (MQQL/MQML) Rod: Carbon steel (chrome plated) (Metal seal) Sleeve: Special stainless steel (Metal seal) Piston: Special stainless steel (Metal seal) Lateral load resistance increased by built-in ball bushing . MQQT type made of fluororesin. Patented floating mechanism (PAT.) facilitates stable sliding resistance without galling due to shaft slippage.
High speed, High frequency actuation H type (without fixed orifice) achieves speeds up to 3,000 mm/s, and continuous actuation up to 50 cycles per second. (MQMLH) Recommended Circuit Examples Example 1) Uniform & low speed actuation (no control of cylinder output) Example 3) High speed & high frequency actuation Example 2) Low speed with output control . When using a solenoid valve, use a metal seal type (VQ, VQZ, SQ series, etc.). . When using a solenoid valve, use a metal seal type (VQ, VQZ, SQ series, etc.). Precision restrictors Solenoid valve Mist separator (0.3 μm or less) Air filter (5 μm or less) Air filter (5 μm or less) IR (Precision regulator) W Solenoid valve Mist separator (0.01 μm or less) (0.3 μm or less) ITV (Electro-pneumatic regulator) Air filter (5 μm or less) IR (Precision regulator) W . When performing control of cylinder output, do not create a restriction circuit using a speed controller, etc. Pressure inside the cylinder will drop and control will become impossible. Always control actuation by means of pressure control. When using as a pressure or tension control (external power drive), air from inside the cylinder will be expelled through the regulator relief port. If the pressure inside the cylinder is expected to rise due to deformation (stroke) or drive speed, please install an air tank between cylinders. Applications based on low friction specification 1) Operating resistance will vary with an offset load. Be sure to properly align the rod axis with the load and direction of movement when connecting. When an offset load is expected, provide a suitable mechanism such as a floating joint. 2) Use clean air (atmospheric pressure dew point temperature .10°C or less). Using the AM series mist separator (nominal filtration rating of 0.3 μm or less), or the AM + AMD series (nominal filtration rating of 0.01 μm or less) is recommended.
