The AirTAC Airtac MA Mini Cylinders MA40X50SU is a genuine double acting standard round-body mini air cylinder with a Ø40mm bore and 50mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The biggest bore in the MA line, the MA40X50SU packs 628.3 N of push and 527.8 N of pull at 0.5 MPa into a 50 mm stroke - double acting, with fixed bumper pads absorbing stroke-end shock. Its stainless barrel and 16 mm hard-chrome plated rod handle humid or outdoor sites that age painted mini cylinders quickly.
Feed it 0.15-1.0 MPa (22-145 psi) at speeds up to 800 mm/s. A standard magnet accepts CMSG, DMSG or EMSG switches without a special-order piston. When air drops the rod falls under gravity; a rod lock or pilot check valve is the fix, not the bumpers.

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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| -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 (double rod, 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.
Swings a divertor that nudges loaded boxes onto a spur conveyor; 628 N at 0.5 MPa moves cartons equal to about 32 kg of vertical lift.
Presses bushings into housing bores on a small assembly stand; 377 N of derated working force covers light interference fits.
Raises a 15 kg locating plate on a welding fixture; even halved, the 64 kgf theoretical lift at 0.5 MPa leaves ample headroom.
Step down to the 32 mm bore for 402.2 N push, or step up to the MAC family, which adds variable air cushioning plus 50 and 63 mm bores when 628.3 N is not enough. FA flange or LB foot mounting suits the heavier frame loads this bore generates. At 50 mm stroke, rod bending is a minor concern, but keep side loads off the 16 mm rod, and note that position is not held on air loss.
Quick checklist
At 0.5 MPa: 628.3 N push and 527.8 N pull. At 0.7 MPa: 879.6 N push and 738.9 N pull. Maximum theoretical force is 128.1 kgf at 1.0 MPa. Bore 40 mm, rod 16 mm, 1/8" ports, M12x1.25 rod thread.
The round stainless barrel plus hard-chrome plated carbon-steel rod resist rust in damp, food or outdoor conditions, while fixed bumper pads trim stroke-end impact at speeds up to 800 mm/s - no adjustment and no extra cushion hardware needed.
