Airtac MFJ Adjustable Mini Cylinder MFJ25X160-10S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X160-10S is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MFJ25X160-10S
Dial in your exact extend position on the factory floor with the AirTAC MFJ25X160-10S, a JIS-standard round-body mini cylinder built for double-acting service. An external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving you a usable 150-160 mm forward travel window without buying a new unit or adding external stops. The riveted SUS304 stainless barrel and aluminium covers resist mild washdowns, and the body is deliberately shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
This 25 mm bore model delivers 245.3 N of push force and 206.1 N of pull force at 0.5 MPa, peaking at a theoretical 50 kgf at 1.0 MPa. The integrated -S piston magnet supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing. It uses fixed TPU bumper pads to decelerate the stroke end, operates at 30-800 mm/s, and features a 1/8" port with an M10x1.25 male rod thread.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X160-10S Is Used
Changeover Stations
Fine-tune the 150-160 mm extend position by up to 10 mm during product format changes, avoiding the need to physically swap out cylinders for slightly different part heights.
Trial Fit Rigs
Safely test end-of-stroke contact points on new assemblies using the 245.3 N push force, dialing back the forward travel incrementally until the exact kinematic position is proven.
Variable Position Stops
Act as a dynamic mechanical stop that can be adjusted on-site for 25 mm bore tooling setups, leveraging the SUS304 body to withstand intermittent washdown in light manufacturing.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X160-10S the Right Cylinder?
When sizing this series, compare the real 0.5 MPa push figures: the MFJ20 yields 157 N, this MFJ25 provides 245.3 N, and the larger MFJ32 hits 402.2 N. This 25 mm bore strikes a middle ground, offering a computed safe working load of roughly 147 N (about 60% of its 0.5 MPa push force) and lifting approximately 12.5 kg vertically with a 2:1 safety margin. The 10 mm adjustable window is perfect for trial fits and line changeovers where the exact end position is not yet final.
Remember that the external adjuster only sets the extend end position; it is not a mid-stroke lock. A plain cylinder drifts if air pressure drops, so install an external rod lock or pilot-operated check valve if you need to hold a load securely. Mounting options include LB foot, FA flange, and TC trunnion (no SDB), and the -S magnet ensures full compatibility with CMSG, DMSG, and EMSG sensors.
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 MFJ25X160-10S FAQ
This 25 mm bore double-acting cylinder has a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with 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 10 mm on-site, allowing a usable forward travel of 150-160 mm; the retract stroke remains full. It uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion. The included -S magnet enables CMSG, DMSG, and EMSG sensors.
