The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X60SCA is a genuine double acting + 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.
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the built-in piston magnet (-S suffix) enables direct mounting of CMSG, DMSG or EMSG switches for position sensing. A 1/8" port and M8x1.25 male rod thread complete the pneumatic interface.
For the same bore and stroke, this JIS-standard round-body unit is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. It provides a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The rear CA pivot cover suits articulated rod-end loading, and the front cover carries a fixed anti-impact pad alongside the adjustable cushions to further smooth deceleration.

Ejecting small plastic moulded parts at speed, using the adjustable air cushion to bring the 8 kg load to a smooth stop without bouncing.
Diverting light cartons on a packing line where the compact JIS body saves space and the CA pivot accommodates slight misalignment.
Moving delicate diagnostic samples horizontally, relying on the 94 N safe working load and needle-set deceleration to prevent spillage.
When sizing this 20 mm bore actuator, step down if speeds are low or loads are trivial, but step up to the MFC25 (245.3 N push at 0.5 MPa) if you need extra thrust margin. The variable air cushion is essential when cycling at high speeds or moving sensitive masses, as it prevents harsh end-of-stroke impacts. Note that the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If the application must hold a load on air loss or when the valve is centered, fit an external rod lock or pilot-operated check valve, because the piston will drift. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets, and the -S magnet allows CMSG, DMSG, or EMSG sensors to be fitted.
Quick checklist
This 20 mm bore double-acting cylinder has a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. The variable air cushion at both ends uses a needle valve to restrict exhaust flow and decelerate the piston near the stroke end; it is not a brake and will not hold the load if air pressure is lost.
