Airtac MFJ Adjustable Mini Cylinder MFJ40X160-100
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ40X160-100 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFJ Adjustable Mini Cylinder MFJ40X160-100
Trimming the extend stroke by up to 100 mm on site, the AirTAC MFJ40X160-100 lets you set a usable 60 to 160 mm forward travel without buying a new cylinder or adding external stops. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, delivering a shorter mounting envelope than an ISO 6432 unit for the same 40 mm bore and 160 mm stroke.
Driven by a 16 mm rod and a 1/4" port, the 40 mm bore generates 628.3 N of push force at 0.5 MPa. That translates to a safe working load of roughly 377 N, or lifting about 32 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impacts across the 30 to 800 mm/s speed range, and because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ40X160-100 Is Used
Changeover Stations
Dial in the 60 to 160 mm extend position during format swaps on packaging lines, using the 100 mm adjuster window to hit new stops rapidly.
Trial Fit Rigs
Leverage the 628.3 N push force to seat test components, shortening the stroke on the fly until the exact clamping distance is proven.
Variable Position Stops
Set precise end-of-travel limits for 40 mm bore tooling without machining external bumpers, relying on the 1/4" port for swift pneumatic response.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ40X160-100 the Right Cylinder?
Choosing between the two MFJ bores comes down to force: this 40 mm version outputs 628.3 N push at 0.5 MPa, whereas the MFJ32 provides 402.2 N. The 100 mm adjustable window is ideal for trial fits and line changeovers where the exact end position is unknown, letting you fine-tune the extend stop on the fly. Mounting options include LB foot, FA flange and TC trunnion, with no SDB or back-cover option on this adjustable build.
Remember that the external adjuster only sets the extend end point; it is not a mid-stroke lock. A plain cylinder drifts on air loss, so for holding a suspended load you must add an external rod lock or pilot-operated check valve. If you need position sensing, select the -S magnet variant instead of this non-magnet SKU.
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 MFJ Adjustable Mini Cylinder MFJ40X160-100 FAQ
The 40 mm bore with a 16 mm rod and 1/4" port generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 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, operating between 0.15 and 1.0 MPa at speeds of 30 to 800 mm/s.
An external adjuster shortens the extend stroke by up to 100 mm on site, giving a usable 60 to 160 mm forward travel while retract remains full. Fixed TPU bumper pads decelerate the piston at the stroke end; the adjuster is not a lock, so the cylinder will drift on air loss.
