About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X500-100S
Five hundred millimetres of stroke and a 100 mm tuning band make the MAJ40X500-100S the long-reach member of the MAJ adjustable family. Air works both ways, 628 N out and 528 N back at 0.5 MPa, climbing to 880 N push at 0.7 MPa, while the stop screw shortens the extend stroke by up to 100 mm wherever the machine needs it.
The stainless barrel and hard-chrome rod keep corrosion out of washdown corridors and damp warehouses that chew through painted minis. Treated as working output, expect around 377 N at 0.5 MPa; vertically that margin puts about 32 kg within safe reach of the rod. Bumper pads are fixed, cushioning the stroke ends without the adjustable air cushion you would find on MACJ.

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 (Ø40mm)
| 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.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X500-100S Is Used
Pallet indexing conveyor
A 500 mm pitch indexer steps pallets one station at a time; the 100 mm window absorbs later pitch changes without re-plumbing.
Guard door on a washdown oven
Stainless construction survives the humid, caustic zone around a food oven, driving its 500 mm guard door open and closed all shift.
Tray lift between conveyor levels
Raising stacks of bread trays about 500 mm from a low infeed to a main line, sized so the 32 kg margin covers the heaviest stack.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X500-100S the Right Cylinder?
At this stroke length side load is the real enemy: guide the load on external rails so the 16 mm rod sees thrust only, especially near full extension. Bore 32 (402 N at 0.5 MPa) covers lighter long strokes, and for anything beyond the 628 N class move to a larger series. FA flange and LB foot mounting hold the barrel true, and the adjuster behaves as an extend-side end stop, so it will not arrest a falling load if air escapes.
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 MAJ40X500-100S FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa push reaches 879.6 N and pull 738.9 N. The 1.0 MPa theoretical maximum is 128.1 kgf. Operating window: 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Fixed anti-impact bumper pads decelerate the piston at both ends of the stroke. They are not adjustable air cushions; if you need tunable cushioning on a long stroke, the MACJ series is the better match.
