Airtac MFJ Adjustable Mini Cylinder MFJ40X160-10S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ40X160-10S 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 MFJ40X160-10S
Dial in your end position on the fly with the AirTAC MFJ40X160-10S, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. An external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable extend range of 150 to 160 mm without buying a new unit. The retract stroke remains full length. Because the MFJ body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length while the stainless barrel resists mild corrosion and washdown.
This double-acting 40 mm bore cylinder delivers serious force, pushing 628.3 N and pulling 527.8 N at 0.5 MPa. That translates to a safe working load of about 377 N, or lifting roughly 32 kg vertically with a 2:1 safety margin. It uses a 1/4" port, a 16 mm rod, and fixed TPU bumper pads to decelerate the stroke ends. The -S suffix means a piston magnet is installed, ready for CMSG, DMSG, or EMSG switches.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ40X160-10S Is Used
Changeover Stations
Fine-tune the extend position up to 10 mm during product changeovers, using the 628.3 N push force to seat parts without re machining hard stops.
Trial Fit Rigs
Dial in the exact extend distance on prototype assembly rigs, safely moving loads up to 32 kg vertically while finding the optimal stroke.
Variable Position Stops
Adjust the end of stroke on the fly for variable-position stops in compact machinery where the shorter JIS body saves mounting length.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ40X160-10S the Right Cylinder?
Choose the MFJ40 over the smaller MFJ32 when you need more push: the 40 mm bore gives 628.3 N at 0.5 MPa compared to 402.2 N for the 32 mm. The adjustable stroke is ideal for trial fits and line changeovers where the exact end position is not final, letting you fine-tune the extend by up to 10 mm instead of adding external stops. Mounting options include LB foot, FA flange, and TC trunnion (no SDB). For holding a load on air loss, this cylinder will drift, so add an external rod lock or pilot check valve rather than relying on the bumper.
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 MFJ40X160-10S FAQ
This 40 mm bore cylinder uses a 1/4" port and a 16 mm rod. It pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical max force is 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on site, giving a usable range of 150 to 160 mm, while fixed TPU bumpers decelerate the ends. The -S suffix means a magnet is built in for CMSG, DMSG, or EMSG sensors.
