Airtac MFJ Adjustable Mini Cylinder MFJ25X60-50S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X60-50S is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 60mm stroke, 1/8" 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 MFJ25X60-50S
Fine-tune your extend end position on-site with the AirTAC MFJ25X60-50S, 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 50 mm, giving a usable extend window of 10 to 60 mm without buying a new unit or adding external stops. This riveted, space-saving body is shorter than an ISO 6432 cylinder for the same bore and stroke, and the -S suffix means a piston magnet is pre-installed for CMSG, DMSG, or EMSG switches.
Delivering 245.3 N of push force and 206.1 N of pull force at 0.5 MPa, this double-acting actuator handles trial fits and line changeovers with ease. The Ø10 mm rod uses an M10x1.25 male thread, and the air port is 1/8". For a safe working load, expect around 147 N (about 60% of the 0.5 MPa push figure), which translates to lifting roughly 12.5 kg vertically with a 2:1 margin.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X60-50S Is Used
Changeover Stations
Dial in the 10 to 60 mm extend position on-site during product line changeovers, absorbing setup variance without swapping the cylinder.
Trial Fit Rigs
Use the 245.3 N push force to press test parts, adjusting the end stop in the field until the exact 50 mm window is validated.
Variable-Position Stops
Act as a movable hard stop for light workpieces, leveraging the 12.5 kg vertical lift capacity while fine-tuning the contact point.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X60-50S the Right Cylinder?
When sizing this adjustable-stroke series, compare the real thrust figures: the MFJ20 provides 157 N of push at 0.5 MPa, this MFJ25 hits 245.3 N, and the larger MFJ32 delivers 402.2 N. The 50 mm adjustment window is ideal for changeover stations where the exact end position is not final, letting you dial in the stroke during commissioning. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover here). Because the fixed TPU bumper pads only decelerate the stroke end, the piston will drift on air loss; for a held load, add an external rod lock or pilot check valve rather than relying on the adjuster.
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 MFJ25X60-50S FAQ
This double-acting cylinder has a 1/8" air port and delivers 245.3 N push / 206.1 N pull at 0.5 MPa, 343.4 N push / 288.5 N pull at 0.7 MPa, and a theoretical maximum of 50 kgf at 1.0 MPa. It operates at 30-800 mm/s.
The external adjuster shortens the extend stroke by up to 50 mm on-site; it sets the end position but is not a mid-stroke lock. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors, and fixed TPU bumpers decelerate the stroke ends.
