About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-50S
Small fixture work rarely needs the full stroke every cycle, so the MAJ16X50-50S lets you wind the extend stroke down anywhere within its 50 mm window using the built-in stop screw. This smallest AirTAC MA bore pushes 100.5 N and pulls 86.4 N at 0.5 MPa (140.7 N at 0.7 MPa), which translates into about 60 N of dependable working force - plenty for light clamping and part-present duty.
Construction is the classic MA recipe: a rolled stainless round barrel, aluminium covers and a hard-chrome plated 6 mm rod threaded M6x1.0 that resists coolant mist and washdown. Anti-impact pads are fixed at both stroke ends for quiet deceleration (adjustable cushioning lives in the MACJ series), and the standard magnet means CMSG, DMSG and EMSG sensors mount with zero ordering options. M5x0.8 ports; 0.15-1.0 MPa (22-145 psi); 30-800 mm/s.

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 MAJ16X50-50S Is Used
Adjustable workstop on a CNC fixture
Set the extend stroke anywhere in the 50 mm window to meet each part datum, while the chrome rod shrugs off coolant splash around the machining envelope.
Glue bead press on a carton gluer
Roughly 60 N of practical force at 0.5 MPa presses flap glue evenly without crushing lightweight board, and the trim dial matches different carton heights.
Reject finger on a checkweigher
The built-in magnet drives an EMSG switch so the PLC knows the finger cleared the belt before the next pack arrives, keeping reject timing tight.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X50-50S the Right Cylinder?
At bore 16 there is no step down - the next size up is 20 mm at 157.0 N push (0.5 MPa), then 25 mm at 245.3 N, so choose by load first and trim the stroke second. A 50 mm stroke keeps rod bending negligible, but still guide the load externally rather than side-loading the 6 mm rod. The stop screw defines the extend position only and will not arrest a rod under air loss, so add a latch or clamp where holding matters. LB foot or FA flange mounting, plus an I or Y knuckle, covers most fixture layouts.
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 MAJ16X50-50S FAQ
This bore 16 unit develops 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push and 120.9 N pull at 0.7 MPa; 20.5 kgf is the theoretical peak at 1.0 MPa. Feed it 40 um filtered air at 0.15-1.0 MPa (22-145 psi) - proof 1.5 MPa (215 psi) - and cycle 30-800 mm/s within -20 to +70 C.
The rolled stainless barrel and 20 um hard-chrome rod of the MAJ16X50-50S resist the corrosion from coolant mist, washdown and outdoor exposure that flakes painted minis, while the riveted aluminium covers keep the package slim enough for compact fixture plates.
