Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm 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 MFCJ20X60-50S
Tune both the extend end-point and the end-of-stroke deceleration on-site with this JIS-standard round-body mini cylinder. The MFCJ20X60-50S features a 50 mm adjustable window (usable extend 10-60 mm) and a needle-set variable air cushion at both ends to absorb high-speed shock.
Built with a SUS304 stainless barrel and riveted aluminium covers, the body is deliberately shorter than an ISO 6432 cylinder for the same 20 mm bore and 60 mm stroke, saving valuable mounting length. Delivering 157 N of push force at 0.5 MPa on a 1/8" port, it yields a safe working load around 94 N and lifts about 8 kg vertically. The -S suffix provides a built-in magnet for CMSG, DMSG or EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-50S Is Used
Light Part Ejection
Dial in the exact 10-60 mm extend position to eject delicate plastic parts from a mould, relying on the variable air cushion to prevent impact bounce at 800 mm/s.
Package Diverter
Divert small cartons on a line by tuning the stroke end-point on the fly, using the 157 N push force to push light boxes smoothly onto a side lane.
Lab Test Actuator
Perform repetitive impact trials where the 50 mm adjustable window allows quick stroke changes, while the needle cushion soaks up high-speed kinetic energy safely.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-50S the Right Cylinder?
When sizing this 20 mm bore against the MFCJ25 (which provides 245.3 N push at 0.5 MPa), choose the 20 mm if 157 N is sufficient, as it offers a tighter footprint for lighter high-speed tasks. The external adjuster and dual air cushions excel in changeovers where exact extend positions and shock absorption must be dialed in without remounting hardware.
Remember that the cushion only decelerates the piston near the stroke end and the adjuster sets the end position—neither acts as a mid-stroke lock or brake. If the load must be held on air loss, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover).
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 MFCJ20X60-50S FAQ
This 20 mm bore double-acting cylinder uses a 1/8" air port and an Ø8 mm rod with an M8x1.25 male thread. It generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, and a theoretical maximum of 32 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 near the ends for smooth high-speed motion. The cushion is not a brake or lock; the cylinder cannot hold a load on air loss, so use an external rod lock if position holding is required. The -S magnet enables CMSG, DMSG and EMSG sensors.
