Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm 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 MFCJ Adjustable Mini Cylinder MFCJ20X160-50
Trim the extend stroke by up to 50 mm on site with the AirTAC MFCJ20X160-50, giving a usable 110-160 mm forward travel while retract remains full. This JIS-standard round-body mini cylinder pairs that external adjuster with a needle variable air cushion at both ends to soak up high-speed end-of-stroke shock.
Built with a SUS304 stainless barrel and riveted aluminium covers, the body is shorter than an ISO 6432 cylinder for the same 20 mm bore and 160 mm stroke, saving mounting length. It pushes with 157 N and pulls with 131.9 N at 0.5 MPa (219.8 N / 184.7 N at 0.7 MPa), yielding a safe working load around 94 N or a roughly 8 kg vertical lift with a 2:1 margin. The bore-fixed 1/8" port and M8x1.25 male rod thread simplify plumbing and tooling.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-50 Is Used
Light-Part Trial Fits
Dial in the 110-160 mm extend and tune the needle cushion for smooth, quiet placement of delicate 8 kg assemblies without slamming.
High-Speed Diverting
Shorten the stroke on the fly for changeovers and let the variable air cushion absorb the shock of fast 157 N push strokes.
Lab Automation Stops
Use the 50 mm adjuster window to set precise end positions for test rigs, relying on the SUS304 barrel for mild washdown resistance.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-50 the Right Cylinder?
For light-force changeovers, this 20 mm bore delivers 157 N push at 0.5 MPa; stepping up to an MFCJ25 raises that to 245.3 N if your fixture needs more punch. Choose the adjustable-stroke and variable-cushion combination when you need to tune both the end position and the deceleration of high-speed trial fits. The cushion only decelerates near the stroke end—it is not a lock or brake, so add an external rod lock or pilot check valve if the load must hold position on air loss. Mount via LB foot, FA flange or TC trunnion (no SDB). Because this SKU lacks the -S magnet, it cannot take a CMSG/DMSG/EMSG switch; order the -S variant if you need sensing.
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 MFCJ20X160-50 FAQ
This 20 mm bore double-acting cylinder has a 1/8" port. At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. Speed range is 30-800 mm/s.
No. This specific SKU does not include a magnet, so it cannot host CMSG, DMSG or EMSG switches. You must order the -S variant to enable magnetic sensing. The 50 mm external adjuster only shortens the extend stroke; it does not lock the piston mid-travel.
