About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-75S
A 40 mm bore paired with a generous 75 mm trimming window makes the MAJ40X175-75S the strongest pick in AirTAC's MA mini range. Double-acting on both strokes, it pushes 628.3 N and pulls 527.8 N at 0.5 MPa; at 0.7 MPa push climbs to 879.6 N and the theoretical ceiling is 128.1 kgf at 1.0 MPa. Sizing it at roughly 377 N of real work leaves headroom for friction and pressure sag. The external stop screw lets you trim the 175 mm extend stroke anywhere inside that 75 mm window once the cylinder is mounted.
Construction is a riveted round body: a stainless-steel barrel rolled onto aluminium-alloy covers with a stainless block, plus a hard-chrome plated carbon-steel rod (20 um). That shrugs off washdown and humid air where painted minis would corrode. Fixed anti-impact pads decelerate the rod at each stroke end - they are bumpers, not adjustable air cushions (that is the MAC family). A magnet is built in as standard, so CMSG, DMSG or EMSG switches mount straight on. Runs on 0.15-1.0 MPa (22-145 psi) filtered air at 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 (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 MAJ40X175-75S Is Used
Keg-rack lift on a brewery wash line
The 628 N push at 0.5 MPa raises loaded keg racks, and the stainless barrel survives caustic washdown cycles; the 75 mm window lets technicians fine-seat the rack's top position.
Cross-cut pusher on an extrusion saw
Feeds 175 mm of aluminium profile into the blade, then the stop screw trims travel by up to 75 mm when shorter offcuts are scheduled.
Lid press for 20 L paint pails
Presses snap-on lids at roughly 377 N of working force, with the mechanical stop giving repeatable crimp depth pail after pail.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-75S the Right Cylinder?
At this 628 N class force, bore 40 is the top of the MA family; one step down, the MAJ32 gives 402.2 N push and 345.6 N pull at 0.5 MPa if the load is lighter. Mount with FA flange or LB foot, and fit I or Y rod knuckles where the tooling needs a swivel. On a 175 mm stroke the 16 mm rod should not see side loads - guide the load externally or the rod will bend.
Remember the stop screw is purely a mechanical end stop for extension: it cannot lock the piston mid-stroke, and with air lost the rod still drifts back, so add a pilot-checked valve if position must hold.
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 MAJ40X175-75S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those become 879.6 N and 738.9 N, and theoretical maximum force is 128.1 kgf at 1.0 MPa. The 40 mm bore has a 16 mm chrome rod threaded M12x1.25 and 1/8" ports. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
An external stop screw shortens the extend stroke on site to any position within the ordered 75 mm window; the retract stroke stays full length. It sets the end of travel only - it is not a mid-stroke clamp, and on air loss the piston still drifts.
