About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-40SFA
Bolted flat to a machine face through its FA flange, the MAJ16X50-40SFA trims its 50 mm extend stroke by up to 40 mm with an external stop screw - no shimming, no cylinder swaps between jobs. The 16 mm bore turns 0.5 MPa into 100.5 N of push and 86.4 N of pull, or 140.7 N at 0.7 MPa; budget about 60 N of that rating for real work and you can still lift around 5 kg vertically with a comfortable margin.
Because the stainless barrel, riveted aluminium covers and 20 um hard-chrome rod shrug off splash and humidity, this flange-mounted mini suits food, packaging and outdoor frames where painted minis corrode. Every unit ships with its magnet fitted, so a CMSG or DMSG switch clips onto the barrel without special ordering, and M5x0.8 ports keep the plumbing compact.

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.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-40SFA Is Used
Guard-door latch on a bottling line
The FA flange bolts the cylinder to the machine frame, where the stainless body shrugs off syrup splash and daily washdown around the filler.
Index stop on a rotary indexing table
Trim the stop within its 40 mm window to match pallet pitch; at 0.7 MPa push reaches 140.7 N, ample to arrest light fixtures.
Tote diverter in a warehouse pick module
Flange-mounted above the roller line, the cylinder swings totes into the pick lane while an EMSG switch reports rod position to the PLC.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-40SFA the Right Cylinder?
FA flange mounting suits face-attached duties such as pushers, gates and stops; pick LB feet for base mounting, and I or Y rod knuckles where the load articulates. Size up from bore 16 - the smallest in the range - to 20 mm (157.0 N) or 25 mm (245.3 N) at 0.5 MPa when 100.5 N feels marginal. Treat the stop screw as a stroke end-stop only: it sets the full-extend position, never locks the piston mid-travel, so a rod that must stay put on air loss needs a mechanical latch elsewhere.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-40SFA FAQ
Expect 100.5 N forward and 86.4 N return at 0.5 MPa, 140.7 N forward and 120.9 N return at 0.7 MPa, and up to 20.5 kgf theoretically at 1.0 MPa. The cylinder takes 40 um filtered air between 0.15-1.0 MPa (22-145 psi), tolerates 1.5 MPa (215 psi) proof, and cycles at 30-800 mm/s from -20 to +70 C.
The FA flange bolts the front cover flat against a machine face, ideal for pushers and stops; LB feet handle base mounting, and I or Y rod knuckles connect pivoting links. Keep the M6x1.0 male rod thread in mind when specifying mating clevises.
