Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 70mm 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 MFC20X70U
Dial in end-of-stroke deceleration with the AirTAC MFC20X70U, a JIS-standard round-body mini cylinder built for high-speed actuation. The variable air cushion at both ends uses a needle valve to absorb shock, protecting payloads far better than a fixed bumper. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore unit handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 margin. The 70 mm stroke flat-end U rear cover configuration saves mounting length, as the MFC body is notably shorter than an ISO 6432 cylinder for the same bore and stroke. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70U Is Used
Light-Part Ejection
Cushions the 70 mm stroke ejection of delicate plastic components at high speed, preventing marking or chipping on the finished goods.
Package Diverting
Provides smooth, shock-free routing of small cartons on a conveyor line without bouncing the payload off the belt surface.
Vertical Lift Stops
Raises lightweight trays using its 8 kg vertical lift capacity, relying on the needle valve to soften the upstroke impact.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70U the Right Cylinder?
When sizing this 20 mm bore actuator, step down if loads are light or step up to the MFC25, which provides 245.3 N of push force at 0.5 MPa for heavier demands. The adjustable air cushion is essential when cycling at high speeds or moving sensitive masses, letting you tune the deceleration curve precisely. Keep in mind the cushion only slows the piston near the stroke end; it is not a brake, so fit an external rod lock or pilot check valve if you need to hold a load vertically during air loss.
This model features a 1/8" port, an 8 mm rod with an M8x1.25 male thread, and a flat-end U back cover. Because this base SKU ships without a magnet, it cannot host position switches; specify the -S option if your control system requires CMSG, DMSG, or EMSG sensor feedback.
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 MFC20X70U FAQ
This 20 mm bore double-acting cylinder uses a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet option for sensor feedback. The SUS304 stainless build and adjustable air cushion function independently of the magnet.
