Airtac MSF Single Acting Mini Cylinder MSF20X10SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X10SCA 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 MSF20X10SCA
Delivering 117.5 N of push force at 0.5 MPa, this compact mini cylinder uses air to extend the rod and an internal spring to retract it. Because you only plumb one 1/8 inch port, routing is simpler and the rod fails to the retracted position on air loss. The quoted force is already net of the spring, which requires a 0.2 MPa pressure floor to overcome.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same 20 mm bore and 10 mm stroke. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG switches, and the CA back cover provides a rear pivot. For a practical 2:1 safety margin, expect a safe working load of about 71 N or a 6 kg vertical lift.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X10SCA Is Used
Short-Stroke Clamping
Uses the 117.5 N push force to secure light workpieces, relying on the spring to release the clamp automatically when air is removed.
Part Ejector
Extends 10 mm to knock small components off a line, with the internal spring ensuring the rod retracts clear of the product flow.
Pivot Gate Actuator
Leverages the CA back cover and 6 kg vertical lift capacity to swing a lightweight diverter gate, failing safely closed on air loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X10SCA the Right Cylinder?
If 117.5 N at 0.5 MPa is insufficient, step up to the MSF25 which provides 192.8 N; there is no smaller bore in the MSF range. This 20 mm bore, 8 mm rod unit is ideal for short-stroke clamping or ejecting where the spring return handles the unpowered reset. Remember the 0.2 MPa minimum operating pressure needed to beat the return spring.
Mounting options include LB foot, FA flange, SDB pivot and TC trunnion, while the CA back cover on this SKU adds a direct rear pivot point. Fixed TPU bumper pads absorb end-of-stroke impact across the 50-800 mm/s speed range, as there is no adjustable air cushion.
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 MSF20X10SCA FAQ
It generates 117.5 N of push force at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is single-acting with a spring return, the force is net of the spring, and it requires a minimum operating pressure of 0.2 MPa to function.
No, the internal spring drives the rod to the retracted position on air loss, so it cannot hold an arbitrary mid-stroke load. The -S magnet allows CMSG, DMSG or EMSG sensors to track end positions, but a double-acting MF with an external rod lock is needed for holding.
