Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM
Tuned for rapid cycling, the variable air cushion at both ends of this 20 mm bore actuator absorbs end-of-stroke shock, protecting payloads far better than a fixed rubber bumper. The double-acting design pushes with 157 N at 0.5 MPa and pulls with 131.9 N, yielding a safe working load of about 94 N or a 2:1 vertical lift capacity near 8 kg.
Built with a SUS304 stainless round body and riveted aluminium covers, it resists mild corrosion and washdown while maintaining a footprint shorter than an ISO 6432 cylinder for the same 125 mm stroke. This specific CM-cover SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors; add the -S option if position feedback is required.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM Is Used
Light-Part Ejection
Uses the 157 N push force to snap small plastic parts out of a mould, relying on the variable cushion to stop the rod cleanly without bouncing delicate tooling.
Package Diverting
Swings a lightweight sorting gate at high speed across the 125 mm stroke, where the tuned air cushion silences the impact at the end of each cycle.
Small Assembly Pressing
Presses sub-gram clips into housings with a safe working load around 94 N, using the CM rear cover for compact flush mounting on the machine frame.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM the Right Cylinder?
If 157 N of push at 0.5 MPa leaves no headroom, step up to the MFC25 (245.3 N); there is no smaller bore in the MFC family. The needle-adjustable cushion is essential when driving the 125 mm stroke at high speeds or moving sensitive masses, but remember it only decelerates the piston near the ends—it is not a brake. Because this unit lacks a magnet, you cannot mount reed switches; choose an -S variant for sensing. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion.
For vertical or suspended loads, be aware the piston will drift if air pressure drops or the valve is centred. To hold position securely, fit an external rod lock or a pilot-operated check valve rather than relying on the 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 0.15 – 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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CM FAQ
This 20 mm bore, 125 mm stroke double-acting cylinder has an 8 mm rod with an M8x1.25 male thread and a 1/8" air port. It pushes with 157 N and pulls with 131.9 N at 0.5 MPa; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches. The variable air cushion at both ends only decelerates the piston near stroke end to reduce shock; it is not a lock or brake, so the rod will drift on air loss. Use an external rod lock or pilot check valve for load holding.
