Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90UTC
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90UTC is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 90mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC40X90UTC
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy-duty motion within a compact JIS-standard footprint. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the U flat-end rear cover and TC trunnion mounting support pivoting loads. For the same bore and stroke, this round-body design is notably shorter than an ISO 6432 cylinder, saving valuable machine space.
A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock at high speeds, protecting the load and cutting noise better than a fixed bumper. Operating at speeds of 30-800 mm/s on a 1/4" port, it yields a safe working load of roughly 377 N or lifts about 32 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90UTC Is Used
Package Diverting
Uses the 90 mm stroke to deflect heavy cartons on a high-speed sorter, relying on the variable air cushion to halt the 16 mm rod smoothly without slamming.
Pallet Pressing
Applies up to 879.6 N of push at 0.7 MPa to seat box components, with the TC trunnion absorbing side-play during the pressing cycle.
Gate Actuation
Drives a pivoting flow-control gate in a washdown zone, where the SUS304 barrel shrugs off moisture and the U flat-end cover mounts cleanly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90UTC the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive, the smaller MFC32 bore provides 402.2 N; since 40 mm is the largest available MFC bore, moving up requires a different series. The adjustable air cushion is essential when moving heavy payloads at high speeds, but remember it only decelerates near the stroke end and does not act as a brake. If the application must hold a load on air loss, fit an external rod lock or pilot-operated check valve.
This configuration includes a TC trunnion mount and a U flat-end back cover, ideal for pivot articulation. Because this specific SKU is built without a magnet, it cannot support position sensing; you must specify an -S variant to use CMSG, DMSG, or 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 MFC40X90UTC FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU is manufactured without a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an -S variant for sensing capabilities. Additionally, the variable air cushion only decelerates the piston near stroke end; it is not a lock or brake.
