About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X100-10S
A -10 window means the extend stroke of the MAJ40X100-10S can be shaved by up to 10 mm on site, ideal for dialing in final approach positions without swapping cylinders. This 40 mm bore double-acting unit produces 628 N of push force at 0.5 MPa and 880 N at 0.7 MPa.
A riveted stainless-steel barrel with a 20 um hard-chrome carbon-steel rod shrugs off washdown and humid shop air better than painted minis, while aluminium covers keep the round body slim. For budgeting: about 32 kg is a comfortable vertical lift at a 2:1 margin, since the 628 N push equals roughly 64 kgf. The magnet ships built in for CMSG / DMSG / EMSG switch sensing, and fixed bumper pads cushion stroke ends.

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 MAJ40X100-10S Is Used
Precision depth setting on a bearing-press jig
The 10 mm trim window takes out stack tolerance in fixture building, landing the 628 N push force within fractions of a millimetre.
Battery-handling clamps on warehouse carts
Gripping force of 880 N at 0.7 MPa clamps traction batteries securely, and the stainless barrel copes with charging-station humidity.
OK/not-OK gauge station on automotive brackets
CMSG switch sensing plus a 10 mm adjustable extension stop lets the gauge head clear clamps and confirm bracket seating repeatably.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X100-10S the Right Cylinder?
The 32 mm bore MAJ32X100 delivers 402 N push at 0.5 MPa - drop to it when your load stays under roughly 240 N. Bore 40 tops the MA range at 628 N. Note the 10 mm adjuster only shortens extension and is not a load-holding lock; pressure loss means drift, so use a locking valve for held positions. Match FA flange or LB foot mounts to your fixture, add I or Y rod knuckles where misalignment exists, and keep side loads minimal over the 100 mm stroke.
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 MAJ40X100-10S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa those become 880 N push and 739 N pull. Maximum theoretical force at 1.0 MPa is 128 kgf. Air supply runs 0.15-1.0 MPa (22-145 psi), stroke speed 30-800 mm/s, ports 1/8" on the 40 mm bore.
FA flange and LB foot mounts suit fixed installations, while I and Y rod knuckles absorb slight misalignment. The anti-impact bumper pads are fixed and only decelerate the piston - they are not an adjustable cushion like the MACJ series offers. Every unit ships with the magnet already installed.
