Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 15mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S
When a fixture only needs a few millimetres of push, the MACJ40X15-10S gives you 15 mm of travel and an extend stroke trimmable down by up to 10 mm with the built-in stop screw. This is a double-acting, round-body mini cylinder: a stainless-steel barrel riveted to aluminium covers with a hard-chrome plated rod that shrugs off washdown and damp shop air better than painted minis. Supply air at 0.15-1.0 MPa (22-145 psi) and it runs 30-800 mm/s with a variable air cushion at each end.
The 40 mm bore pushes 628 N at 0.5 MPa (73 psi) - about 377 N once you plan with a sensible margin, or enough to lift roughly 32 kg vertically at a 2:1 factor. Pull force is 528 N. A magnet ships standard, so CMSG, DMSG or EMSG switches drop on without special ordering. Keep in mind the adjuster is an end stop only: if air pressure drops, the rod can still drift - it is not a position lock.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S Is Used
Tablet press reject gate
Ejects a rejected tablet off the die table in one 15 mm flick; the 10 mm trim lets techs match the chute depth.
Bracket presence push-off
Knocks a wrongly seated bracket off an automotive sub-assembly fixture, 628 N at 0.5 MPa being ample for light parts.
Connector pre-seat assist
Nudges a cable connector into its housing before final press in a PCB assembly cell, with cushioning protecting the plug.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S the Right Cylinder?
Compare against neighbours before you commit: the 32 mm bore delivers 402 N at 0.5 MPa and the 50 mm bore 981 N, so this 40 mm unit (628 N) covers mid-range loads in a short 15 mm stroke. The 10 mm trim window is ideal when the stop position must be dialled in by hand, such as a fixed datum ejection. Mounting is FA flange or LB foot, with I and Y rod knuckles for linkages; the built-in magnet needs no special-order piston for CMSG/DMSG/EMSG switches. The adjuster is a travel stop, not a mid-stroke lock.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X15-10S FAQ
At 0.5 MPa (73 psi) it pushes 628 N and pulls 528 N; at 0.7 MPa, 880 N push and 739 N pull. Theoretical maximum is 128 kgf at 1.0 MPa. It is double-acting, runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and the extend stroke trims by up to 10 mm.
The barrel is stainless steel with a hard-chrome plated rod and riveted aluminium covers, so the body resists mild corrosion and washdown where painted mini cylinders would pit. Both ends carry a variable air cushion to soften stops at up to 800 mm/s.
