The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X60-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 60mm stroke, 1/4" 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.
Tune both the extend end-point and end-of-stroke shock on-site with this double-acting, adjustable-stroke mini cylinder. The external adjuster shortens the extend stroke by up to 50 mm (yielding a 10-60 mm usable extend), while the needle variable air cushion at both ends soaks up high-speed kinetic energy. It features a JIS-standard round-body build with a SUS304 stainless barrel and riveted aluminium covers, delivering a shorter mounting length than an ISO 6432 unit of the same bore.
Equipped with a 1/4" port and a 12 mm rod (M10x1.25 thread), the 32 mm bore generates 402.2 N push force at 0.5 MPa. This translates to a safe working load of roughly 241 N, or lifting about 20.5 kg vertically with a 2:1 safety margin. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG switches.

MF-family variants: MF / MFC (double acting ±cushion), MSF / MTF (single acting push / pull), MFD / MFCD (double rod ±cushion), MFJ / MFCJ (adjustable stroke ±cushion). Back covers CA / U / CM. Mounting LB / FA / SDB / TC.
Dial in the 10-60 mm extend stroke on the fly and use the variable air cushion to softly decelerate the 402.2 N push force during high-speed pressing operations.
Fine-tune the extend end-point between product runs without swapping hardware, relying on the 1/4" port and cushioned stops to handle rapid actuation smoothly.
Lift approximately 20.5 kg vertically with a 2:1 safety margin, using the -S magnet and EMSG switches to confirm end positions in compact assembly cells.
Weigh this 32 mm bore (402.2 N push @0.5 MPa) against the larger MFCJ40 (628.3 N @0.5 MPa) or the smaller MFCJ25 (245.3 N @0.5 MPa) based on your payload. This model is ideal for high-speed changeovers where you must dial in the exact 10-60 mm extend position and tune the needle cushion to eliminate shock during trial fits. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover option exists).
The variable air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG or EMSG sensors for position confirmation.
Quick checklist
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm (usable extend 10-60 mm), while the needle variable air cushion at both ends decelerates the piston near stroke end. The -S suffix provides a magnet for CMSG, DMSG or EMSG sensors.
