Airtac MSF Single Acting Mini Cylinder MSF20X60SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X60SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MSF20X60SCM
Delivering 117.5 N of push force at 0.5 MPa, this AirTAC MSF20X60SCM mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8" port, simplifying valve requirements. The spring ensures the rod fails safely to the retracted position on air loss. It cannot be loaded on the return stroke.
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 60 mm stroke, saving mounting length. The riveted construction resists mild washdown. With a safe working load around 71 N, it can vertically lift about 6 kg with a 2:1 margin. The -S suffix adds a piston magnet for position sensing, and the CM suffix denotes a round rear cover.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X60SCM Is Used
Light Parts Clamping
Uses the 117.5 N push force to secure thin components during machining, releasing automatically when air is removed.
Package Ejector
Extends 60 mm to push lightweight cartons off a belt, with the spring ensuring the arm retracts clear of the conveyor.
Small Vertical Lift
Raises loads up to roughly 6 kg against gravity, relying on the single air line to extend while gravity and the spring return it.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X60SCM the Right Cylinder?
Choose this 20 mm bore if your task requires a compact spring-return action, such as clamping or ejecting light parts. It provides 117.5 N at 0.5 MPa (181.3 N at 0.7 MPa). If your load exceeds the safe working load of roughly 71 N, step up to the MSF25, which yields 192.8 N at 0.5 MPa. There is no smaller MSF bore available. Ensure your supply stays at or above the 0.2 MPa floor; below this, the return spring overcomes the air pressure and the rod will not extend.
This specific SKU includes the -S magnet for CMSG, DMSG, or EMSG switches and features a CM round-end back cover. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. End-of-stroke deceleration relies on fixed TPU bumper pads, 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 MSF20X60SCM FAQ
The net push force is 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is a single-acting spring-return cylinder, it requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and extend the rod.
No. On air loss, the internal spring drives the rod to the fully retracted rest position; it cannot hold an arbitrary mid-stroke load. The -S magnet allows CMSG/DMSG/EMSG sensors to track end positions, but for holding a mid-stroke load you need a double-acting MF cylinder with an external rod lock.
