About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X450-100S
A 450 mm reach is unusual in a mini body, yet the MAJ40X450-100S fits it into the rolled stainless round barrel of the MA series, still within the 500 mm standard stroke limit for the 40 mm bore. Output is 628 N pushing at 0.5 MPa and 880 N at 0.7 MPa. The -100 window is the widest trim the range offers: a stop screw lets you shorten the extend stroke to as little as 350 mm on site, no cylinder swap needed.
Converted to practical terms, that is about 377 N of usable force at 0.5 MPa - lifting roughly 64 kg vertically, or 32 kg with a 2:1 safety margin. The 16 mm hard-chrome rod copes with the long travel when the load is guided, and the stainless barrel plus riveted aluminium covers stand up to washdown and outdoor air. The piston magnet is standard equipment, so CMSG, DMSG or EMSG switches mount without a special order.

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 MAJ40X450-100S Is Used
Conveyor diverter gate
Swings a divert gate across a 450 mm conveyor spur; the 100 mm trim adapts the throw to different carton widths.
Sliding oven door drive
Opens and closes a bakery oven's sliding door, where the stainless barrel handles heat-adjacent humidity.
Carton stacker lift
Hoists stacked cartons up a discharge chute; 32 kg vertical capacity with margin suits most shelf-pack loads.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X450-100S the Right Cylinder?
Step down to the MAJ32 (402 N push at 0.5 MPa) if the load is lighter; there is no step up, as 40 mm is the largest MA bore. A 450 mm stroke magnifies any side load, so guide the workpiece and couple through an I or Y knuckle instead of bolting directly to the 16 mm rod. FA and LB mountings are the standard fixing points. The trim screw is purely a positional end stop on extension - under lost air pressure the rod can still move, so add a valve or lock where holding matters.
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 MAJ40X450-100S FAQ
Push 628 N and pull 528 N at 0.5 MPa; push 880 N and pull 739 N at 0.7 MPa; 128 kgf theoretical maximum at 1.0 MPa. The MAJ40X450-100S is double-acting, takes 0.15-1.0 MPa (22-145 psi) of filtered air, works from -20 to +70 C at 30-800 mm/s, ports at 1/8 in., and its extend stroke is trimmed up to 100 mm by the stop screw.
Externally guide the load so side forces never reach the 16 mm hard-chrome rod, and couple through an I or Y knuckle for pivoting motion. The stainless rolled barrel resists corrosion in wet or outdoor plants, and the built-in magnet - standard on every MA cylinder - lets CMSG, DMSG or EMSG switches signal mid-travel and end positions.
