Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-75 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MFCJ25X150-75
Tune both the extend end-point and the end-of-stroke deceleration on-site with this 25 mm bore, 150 mm stroke adjustable cylinder. An external adjuster shortens the extend stroke by up to 75 mm (usable range 75-150 mm), while a needle-set variable air cushion at both ends soaks up high-speed shock. The riveted SUS304 stainless round body with aluminium covers is JIS-standard, packing the same bore and stroke into a shorter mounting length than an ISO 6432 unit.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa (343.4 N / 288.5 N at 0.7 MPa), it handles a safe working load of roughly 147 N or lifts about 12.5 kg vertically with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread simplify integration. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; specify the -S variant if position feedback is required.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-75 Is Used
High-Speed Forming Press Feed
Dial in the 75-150 mm extend stroke on the fly and use the needle air cushion to absorb shock when positioning 12 kg metal blanks at 800 mm/s.
Variable-Position Diverter Gate
Perfect for changeovers where the divert distance shifts; shorten the extend end by up to 75 mm without swapping hardware while cushioning the high-speed impact.
Adjustable Carton Flap Folder
Tune the end position for mixed carton sizes on a single line. The 245.3 N push force easily handles cardboard folding arms at rapid cycle rates.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-75 the Right Cylinder?
When sizing this series, compare the real thrust figures: an MFCJ20 provides 157 N @0.5 MPa, this MFCJ25 hits 245.3 N, and an MFCJ32 delivers 402.2 N. Choose the 25 mm bore when your load sits in that 147 N safe-working zone and you need on-site stroke tuning for trial fits or high-speed changeovers where the exact end position varies.
The variable air cushion is strictly for decelerating the piston near stroke end—it is not a lock or brake. If the load must be held on air loss or when the valve is centred, the piston will drift; install an external rod lock or pilot-operated check valve. Mounting options are LB foot, FA flange, or TC trunnion (no SDB or back-cover mount exists for this adjustable build).
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 MFCJ25X150-75 FAQ
This double-acting cylinder provides 245.3 N push and 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical max force is 50 kgf at 1.0 MPa. It operates at 30-800 mm/s, uses a 1/8" port, and has an M10x1.25 male rod thread.
The external adjuster shortens the extend stroke by up to 75 mm (usable range 75-150 mm); retract remains full. The variable air cushion at both ends decelerates the piston near stroke end but does not lock or hold the load. This specific SKU has no magnet (-S omitted), so it cannot accept CMSG/DMSG/EMSG sensors.
