Airtac MFCJ Adjustable Mini Cylinder MFCJ25X60-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X60-50S is a genuine double acting, adjustable stroke + cushion 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 MFCJ Adjustable Mini Cylinder MFCJ25X60-50S
Dial in exact end positions and absorb high-speed shock with the AirTAC MFCJ25X60-50S. This JIS-standard round-body mini cylinder features a 50 mm external adjuster that shortens the 60 mm extend stroke on-site, paired with a needle variable air cushion at both ends for smooth deceleration.
Built with a SUS304 stainless barrel and riveted aluminium covers, the riveted construction is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length. The 25 mm bore delivers 245.3 N push force at 0.5 MPa via a 1/8" port. With a safe working load around 147 N, it lifts about 12.5 kg vertically with a 2:1 margin. The built-in -S magnet supports CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X60-50S Is Used
Component Seating Tests
Fine-tune the 10 to 60 mm extend stroke during trial fits and rely on the variable air cushion to softly seat delicate electronic components without impact shock.
High-Speed Diverter
Sort light packages on a line using the 245.3 N push force, adjusting the stroke on the fly for different carton sizes while the needle cushion absorbs the high-speed return impact.
Vertical Lift Stops
Lift approximately 12.5 kg loads vertically with a 2:1 safety margin, using the external adjuster to set exact upper stopping positions without re-mounting the cylinder.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X60-50S the Right Cylinder?
When sizing this series, compare the real thrust figures: the 25 mm bore provides 245.3 N push at 0.5 MPa, sitting neatly between the MFCJ20 at 157 N and the MFCJ32 at 402.2 N. Choose this 25 mm option when your changeover requires both a tunable 10 to 60 mm extend window and precise end-of-stroke deceleration for shock-sensitive trial fits.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back cover). Remember that the air cushion only decelerates the piston near stroke end; it does not hold the load. If air pressure drops, the piston drifts, so fit an external rod lock or pilot check valve for suspended loads.
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 MFCJ Adjustable Mini Cylinder MFCJ25X60-50S FAQ
This 25 mm bore double-acting cylinder uses a 1/8" port and generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm on-site, while the variable air cushion at both ends uses a needle valve to decelerate the piston smoothly at high speeds. The cushion is not a brake; for position holding on air loss, install an external rod lock or pilot check valve. The -S magnet allows CMSG, DMSG or EMSG sensors.
