The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X140SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 140mm stroke, 1/4" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
Near the top of the mini-cylinder force ladder, the MAC50X140SCA turns 0.5 MPa into 981 N of push (1374 N at 0.7 MPa) inside a compact 50 mm round body. Instead of tie rods, the stainless barrel is rolling-packed onto the aluminium covers with a stainless block, sealing the grease-retaining two-way piston seal for long, leak-free cycles - and the hard-chrome plated rod shrugs off the rust that claims painted-steel minis in food plants and outdoors.
Design around about 589 N of working force at 0.5 MPa; vertically, the theoretical 100 kg lift drops to a comfortable 50 kg part with a 2:1 margin. A variable air cushion at both ends lets you run near the 30-800 mm/s speed band without cover hammering, the piston magnet is standard equipment for CMSG / DMSG / EMSG switches, and the CA pivot cover mounts linkages without adaptors. Operating range is 0.15-1.0 MPa (22-145 psi), -20 to +70 C.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.

|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.
| MAC | Standard round-body mini cylinder (double-acting, variable cushion). |
|---|---|
| 50 | Bore size in mm. |
| ×140 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Driving a steel date-code die into plastic bottle caps: 1374 N at 0.7 MPa makes a clean mark, and the cushion stops the die ringing at bottom of stroke.
Raising 50 kg fixture pallets between bench levels on a 140 mm rise - within the bore's vertical capability once a 2:1 margin is respected.
Pushing a roll pallet home to its stop at a pick station; the stainless barrel handles cool-room condensation that rusts painted minis.
Compare before committing: the 40 mm bore offers 628 N push at 0.5 MPa and the 63 mm bore 1558 N, so 50 mm is the middle choice when your duty falls near 590 N of usable force. If the load could drop when air fails - a lift, a counterweight - fit a rod lock or pilot check valve, because a standard MAC will coast freely. FA flange and LB foot anchor it to fixed frames, the CA pivot cover suits linkage mounts, and every unit already carries the magnet for CMSG / DMSG / EMSG switches. At 140 mm of stroke, align the thrust or add an external guide; side loads will wear the 16 mm rod and bushing early.
Quick checklist
Rated at 981 N push and 881 N pull with 0.5 MPa supply, 1374 N push and 1233 N pull at 0.7 MPa, and up to 200.1 kgf theoretical at 1.0 MPa. That is from the same double-acting, cushioned package running on 0.15-1.0 MPa (22-145 psi).
The barrel is stainless steel and the rod is hard-chrome plated carbon steel, so mild corrosive and wet conditions that rust painted minis are not a problem; the rolling-packed aluminium covers keep the joint sealed. It works from -20 to +70 C.
