Airtac MFJ Adjustable Mini Cylinder MFJ40X175-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ40X175-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MFJ40X175-10
Trim the extend end by up to 10 mm directly at the fixture with the AirTAC MFJ40X175-10, giving a usable forward travel of 165 to 175 mm. This JIS-standard round-body mini cylinder pairs a SUS304 stainless barrel with riveted aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke while resisting mild washdown.
The 40 mm bore delivers 628.3 N of push force and 527.8 N of pull at 0.5 MPa, peaking at a theoretical 128.1 kgf at 1.0 MPa. It uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors; fixed TPU bumper pads absorb end-of-stroke impacts rather than acting as an adjustable air cushion.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ40X175-10 Is Used
Changeover Dial-In
Fine-tune the 165 to 175 mm extend position during product family changeovers, using the 628.3 N push force to seat varying fixture heights without swapping hardware.
Prototype Stroke Setup
Dial in the exact end-of-travel stop on trial assembly rigs, leveraging the 10 mm adjuster window to test multiple extend distances before finalizing the layout.
Variable Press Stops
Adjust the downward extend limit on light-duty pressing stations, relying on the 40 mm bore's 527.8 N pull force to retract the tooling smoothly after each cycle.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ40X175-10 the Right Cylinder?
Weigh the two available bores against your motion needs: the MFJ40 shown here provides 628.3 N of push at 0.5 MPa, whereas the smaller MFJ32 offers 402.2 N. Choose the 40 mm bore when moving heavier jigs or overcoming high friction, and step down to the 32 mm if your payload is lighter and you want a slimmer footprint. Both options share the 1/4" port and the 30 to 800 mm/s speed range.
The 10 mm external adjuster is ideal for trial fits and line changeovers where the exact end position is not yet final, letting you shorten the extend stroke without buying a new cylinder or adding external stops. Mount via LB foot, FA flange or TC trunnion (there is no SDB or back-cover option on this build). Note that a plain cylinder drifts on air loss—the fixed bumper decelerates the stroke but never locks the load, so fit an external rod lock or pilot check valve if you need to hold vertical position.
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 MFJ40X175-10 FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It 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, with fixed TPU bumper pads handling end-of-stroke deceleration.
The external adjuster shortens the extend stroke by up to 10 mm on site, giving a usable forward travel of 165 to 175 mm; the retract stroke remains full. This adjuster sets the end position and is not a mid-stroke lock. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors—you would need the -S variant for magnetic switching.
