Airtac MSF Single Acting Mini Cylinder MSF20X10U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X10U is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MSF Single Acting Mini Cylinder MSF20X10U
Generating 117.5 N of push force at 0.5 MPa, this compact 20 mm bore mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only need to plumb one 1/8" port, simplifying valve requirements while ensuring the rod fails to the retracted position on air loss. The SUS304 stainless round-body construction resists mild washdown environments, and its riveted JIS-standard envelope is notably shorter than an ISO 6432 cylinder of the same bore and stroke. This specific SKU features a U flat-end rear cover and uses an M8x1.25 male rod thread.
The quoted push force is already net of the return spring, meaning it represents your actual usable output. For practical sizing, a safe working load is roughly 71 N, which translates to clamping or vertically lifting about 6 kg with a 2:1 safety margin. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion. Note that this base model lacks a magnet and cannot accept position sensors; adding an -S suffix enables CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X10U Is Used
Short-Stroke Clamping
Apply the 71 N safe working load to hold light plastic or cardboard components securely against a fixture during a rapid machining or gluing process.
Part Ejection Gate
Deploy the 10 mm stroke to push small finished parts off a conveyor belt quickly, with the spring ensuring the gate clears automatically when air is removed.
Light Vertical Lift
Raise lightweight jig plates or product trays weighing up to 6 kg, relying on the spring return to lower the load safely if pneumatic pressure drops.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X10U the Right Cylinder?
If the 117.5 N @0.5 MPa output is insufficient, step up to the MSF25 bore, which provides 192.8 N @0.5 MPa. As the smallest bore in the MSF family, there is no smaller single-acting push option below 20 mm. Ensure your supply pressure stays at or above the 0.2 MPa floor; below this threshold, the internal spring overcomes the air pressure and forces the rod back to its retracted state. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your frame. Because this specific configuration has a 10 mm stroke and a U flat-end cover, it is ideal for very tight spacing where only a short, decisive ejection or clamping motion is required.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MSF Single Acting Mini Cylinder MSF20X10U FAQ
The bore 20 single-acting push force is 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. These figures are net of the return spring. You must maintain a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need to specify the -S variant for position sensing. Additionally, the spring only returns the rod to rest on air loss; it will not hold a mid-stroke load.
