Airtac MFJ Adjustable Mini Cylinder MFJ40X200-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ40X200-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MFJ40X200-10
Fine-tune your extend end position on-site with the AirTAC MFJ40X200-10, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. An external adjuster lets you shorten the forward stroke by up to 10 mm, giving a usable extend range of 190 to 200 mm without buying a new unit or adding external stops.
This double-acting 40 mm bore actuator delivers 628.3 N push and 527.8 N pull at 0.5 MPa, translating to a safe working load of roughly 377 N or a 32 kg vertical lift with a 2:1 margin. The riveted body is shorter than an equivalent ISO 6432 cylinder, saving mounting length, while the fixed TPU bumper pads absorb end-of-stroke impacts. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ40X200-10 Is Used
Changeover Stations
Dial in the 190-200 mm extend position during product line changeovers, using the 10 mm adjuster to set new end stops without swapping hardware.
Trial Fit Rigs
Leverage the 628.3 N push force to seat components, making micro-adjustments to the forward stroke until the exact travel distance is proven.
Variable Position Stops
Push loads up to 377 N safely, fine-tuning the extend end by up to 10 mm to accommodate varying material thicknesses on the fly.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ40X200-10 the Right Cylinder?
When sizing these actuators, compare the real thrust: this MFJ40 provides 628.3 N push at 0.5 MPa, whereas the smaller MFJ32 offers 402.2 N. Choose the 40 mm bore when moving heavier jigs or overcoming friction, and use the 10 mm adjuster window to dial in the exact 190-200 mm extend position during trial fits or line changeovers. Mounting options include LB foot, FA flange, and TC trunnion (no SDB). Because air pressure alone cannot hold a load if air is lost, add an external rod lock or pilot check valve for vertical applications.
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 MFJ40X200-10 FAQ
This 40 mm bore cylinder features a 1/4" port, a 16 mm rod with an M14x1.5 male thread, and fixed TPU bumpers. It delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical max of 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on-site, but it only sets the end position and is not a mid-stroke lock. The piston will drift on air loss, so use an external rod lock or pilot check valve if you need to hold a load vertically.
