Airtac MSF Single Acting Mini Cylinder MSF40X60U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X60U is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm stroke, 1/4" 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 MSF40X60U
Delivering 535.3 N of push force at 0.5 MPa (786.5 N at 0.7 MPa), this AirTAC MSF40X60U is a JIS-standard round-body mini cylinder built for demanding clamping and ejection tasks. It features a SUS304 stainless steel barrel with riveted aluminium covers, offering excellent resistance to mild corrosion and washdown environments. The U flat-end rear cover facilitates direct face mounting, while the 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic connections.
As a single-acting push type, air extends the rod and an internal spring retracts it, meaning you only pipe and valve one port. The quoted force is already net of the spring, which requires a minimum 0.2 MPa operating pressure to overcome. For practical sizing, expect a safe working load of about 321 N, or a vertical lift capacity of roughly 27.3 kg with a 2:1 margin. This 60 mm stroke unit uses fixed TPU bumper pads for end-of-stroke deceleration and, without the -S option, cannot accept magnetic sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X60U Is Used
Heavy-Duty Part Clamping
Leverage the 535.3 N push force to secure heavy metal castings during machining, with the spring ensuring the clamp retracts safely on air loss.
Package Ejection
Use the 60 mm stroke to push dense cartons off a conveyor line, relying on the single-acting design to simplify valve requirements.
Pallet Gating
Actuate heavy diverter gates on a packaging conveyor where the SUS304 stainless barrel withstands periodic washdowns.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X60U the Right Cylinder?
When sizing this 40 mm bore unit, evaluate both ends of the scale: if 535.3 N at 0.5 MPa is excessive, stepping down to the MSF32 yields 323.3 N at 0.5 MPa; conversely, 40 mm is the largest bore available in the MSF series. This model is ideal for spring-return clamping, ejecting, or gating where the load cannot be driven on the retract stroke. Remember the 0.2 MPa pressure floor needed to beat the return spring.
Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your layout. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG switches—choose an -S variant if position feedback is required. Note that for the same bore and stroke, this JIS-standard body is shorter than an ISO 6432 cylinder, saving valuable machine space.
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 MSF40X60U FAQ
This single-acting cylinder provides a net push force of 535.3 N at 0.5 MPa and 786.5 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
No, the spring constantly drives the rod to the retracted rest position when air is released, so it cannot hold an arbitrary mid-stroke load. Additionally, this SKU lacks the -S magnet, so it cannot be fitted with CMSG, DMSG, or EMSG sensors.
