Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X90SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X90SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 90mm 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 MFC20X90SCM
Delivering 157 N of push force at 0.5 MPa, the MFC20X90SCM is a JIS-standard round-body mini cylinder built for double-acting operation. It features a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. For the same bore and stroke, this unit is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing the 90 mm stroke.
A defining trait is the variable air cushion at both ends, letting you turn a needle to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches, while the CM round-end rear cover suits compact pivot layouts. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X90SCM Is Used
Light Part Ejection
Uses the 94 N safe working load to push small plastic components out of a mould, relying on the variable air cushion to prevent marking at high cycle rates.
Package Diverting
Swings a lightweight guide arm to sort small cartons on a line, where the compact JIS body length fits neatly within tight conveyor side frames.
Sub-assembly Pressing
Seats delicate electronic clips into housings, using the needle-set deceleration to avoid crushing parts at the end of the 90 mm travel.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X90SCM the Right Cylinder?
If 157 N at 0.5 MPa is insufficient, step up to the MFC25, which provides 245.3 N; since 20 mm is the smallest MFC bore, there is no smaller option. The adjustable air cushion matters most when driving heavier masses at high speeds, as it decelerates the piston near the stroke end to reduce impact. Note that this cushion only slows the load and does not act as a brake, so if you need to hold position on air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion, and the 1/8 inch port ensures adequate flow for the 30-800 mm/s speed range.
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 MFC20X90SCM FAQ
This 20 mm bore cylinder has a 1/8 inch port and an M8x1.25 male rod thread. At 0.5 MPa it pushes 157 N and pulls 131.9 N. 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, the piston will drift on air loss. The variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it is not a lock or brake. To hold a vertical load, you must add an external rod lock or pilot-operated check valve.
