Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 300mm 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 MFC20X300U
Soaking up end-of-stroke shock at high speeds, the AirTAC MFC20X300U relies on a needle-set variable air cushion at both ends rather than a fixed bumper. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving it a shorter overall body than an ISO 6432 cylinder for the same 20mm bore and 300mm stroke.
Generating 157N of push force at 0.5MPa (131.9N pull), it handles a safe working load of about 94N and lifts roughly 8kg vertically with a 2:1 margin. The U flat-end rear cover suits tight layouts. Note this SKU lacks the -S magnet, so it cannot take CMSG/DMSG/EMSG switches; the 1/8" port and M8x1.25 rod thread are standard for this bore.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300U Is Used
Light-Part Diverting
Pushes small packages on a 300mm stroke at high speed; the variable air cushion prevents end-of-stroke slamming that could scuff fragile goods.
Film Feed Roll
Handles the 94N safe working load to tension and shift packaging film, using the U flat-end cover for flush rear mounting against machine frames.
Small Assembly Press
Delivers 157N at 0.5MPa to seat lightweight bearings, relying on the adjustable needle to decelerate the 8mm rod smoothly before the end of travel.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300U the Right Cylinder?
If 157N at 0.5MPa falls short, step up to the MFC25 (245.3N); since 20mm is the smallest MFC bore, there is no smaller option. The variable air cushion is essential when moving heavy loads at speed, but remember it only decelerates near stroke end—it is not a lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve to hold a suspended load.
Mount this cylinder using LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this specific SKU has no -S magnet, position sensing is impossible; order an -S variant if you require CMSG/DMSG/EMSG switches.
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 MFC20X300U FAQ
This 20mm bore, 300mm stroke double-acting cylinder pushes 157N and pulls 131.9N at 0.5MPa. At 0.7MPa it pushes 219.8N and pulls 184.7N, with a theoretical max of 32kgf at 1.0MPa. It uses a 1/8" port, an 8mm rod, and operates at 30-800mm/s.
This SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG switches. The variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end, cutting shock at high speeds; it is not a brake and will not hold the load on air loss.
