Product Description

An air cylinder suitable for all driving ranges, from low pressure, low speed, uniform speed and low friction to high pressure, high speed and high-speed response (high frequency).
[Features]
· Covers a range of driving speeds and output controls not possible with standard cylinders thanks to its metal seal structure with minimal sliding resistance.
· Minimal sliding resistance allows low-pressure actuation at 0.005 MPa.
· Low- and uniform-speed actuation. Smooth, uniform-speed actuation ranges as low as 0.3 mm/s.
· Low sliding resistance allows output control in approx. 0.05 N increments. (Based on cylinder piston area × pressure accuracy)
· No increased sliding resistance after not operating for a long period of time.
· Long lifespan: Long service life of 10,000 km or 100 million full cycles.
· Lateral load resistance increased by built-in ball bushing.

Note 1) Value when horizontal. (Use clean, dry and nonfreezing air) However, as the stroke increases, it will likely be affected by the mass of its moving parts and the pressure will likely increase by 0.003 to 0.005 MPa due to an offset load from the mass of the rod.
Note 2) Please refer to the manufacturer's catalog regarding lubrication. This product uses turbine oil (standard type) or lithium soap based grease (high speed / high frequency type) as an initial lubricant. Lubricant may seep out of the rod or the piping port.
Note 3) Control low speed actuation with differential pressure and a speed controller, etc. (Refer to the recommended circuit example in the manufacturer's catalog for details.)
Note 4) The values are only for reference and are not guaranteed.
