Compact Low-Friction Cylinder MQQ Series (Part Numbers)

Compact Low-Friction Cylinder MQQ Series

A compact low-friction cylinder suitable for low pressures, low speeds, uniform speeds and low friction actuation.
[Features]
· Covers a range of actuation speeds and output controls thanks to its metal seal structure with minimal sliding resistance.
· Its minimal sliding resistance allows for low-pressure actuation at 0.005 MPa.
· Smooth and uniform-speed actuation ranges as low as 0.3 mm/s.
· Long lifespan: Long service life of 10,000 km or 100 million full cycles.
· Lateral load resistance: Features built-in ball bushings in the bearings for improved lateral load resistance. (MQQL)
· Its low sliding resistance allows output control in approximately 0.05‑N increments. (Based on cylinder piston area × pressure accuracy)
· No change to sliding resistance, even after extended periods of non-use.

*1: Value when horizontal. (Use clean, dry and nonfreezing air) However, as the stroke increases, it will likely be affected by the weight of its moving parts and the pressure will likely increase by approximately 0.003 to 0.005 MPa due to an offset load from the weight of the rod.
*2: See p. 339 in the SMC catalog regarding information on lubrication. This product uses turbine oil as an initial lubricant. Lubricant may seep out of the rod or the piping port.
*3: Control low speed actuation with differential pressure, speed controllers, etc. (Refer to the recommended circuit example on p. 319 of the SMC catalog for details.)
*4: The values are only for reference and are not guaranteed.
