About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-50S
Clamping and press-fit stations are where the MAJ40X60-50S earns its keep: 628.3 N of push at 0.5 MPa, an extend stroke trimmed within a generous 50 mm window by an external stop screw, and a stainless round barrel with a 20 um hard-chrome rod that laughs off coolant mist around a CNC cell. The aluminium covers are riveted onto the tube, keeping the body compact and sealed.
Leave margin on your fixture: sizing for about 377 N of real clamping force at 0.5 MPa (roughly 60% of the raw rating) keeps the cylinder away from its pressure ceiling. Fixed anti-impact pads at both ends decelerate the piston before metal-to-metal contact - useful when the stop screw is set close to full stroke - and the built-in magnet is standard, so CMSG, DMSG or EMSG switches mount on for clamp-confirmed interlocks.

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 MAJ40X60-50S Is Used
Bushing press-fit
Seats bronze bushings into pump housings - light interference fits sit comfortably inside the roughly 377 N working margin at 0.5 MPa.
Mould insert ejection
Ejects cured inserts from a small moulding fixture, with the fixed bumper pads damping arrival at the trimmed stroke end.
Weld fixture clamp
Holds a bracket against locating pins in a weld cell, the 50 mm window letting the clamp swing clear for manual loading.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-50S the Right Cylinder?
Compare downward: the bore 32 MA cylinder offers 402.2 N at 0.5 MPa and may suffice for lighter weld fixtures, but this 40 mm bore adds 226 N more push for stiff joints or press-fit work, and nothing larger exists in the MA family. Because the 50 mm window lets you back the stop screw off across nearly the full stroke, check that your fixture clears the shortest reach before ordering. The 16 mm hard-chrome rod needs aligned external linkages so side load stays low over the 60 mm travel. Ports are 1/8" per cover; mounting is FA flange or LB foot with I and Y knuckles optional. The stop screw is an end stop only: under air loss the piston is free to move, so use a valve or external lock wherever load 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 MAJ40X60-50S FAQ
Push at 0.5 MPa is 628.3 N, pull at 0.5 MPa is 527.8 N, push at 0.7 MPa is 879.6 N, and the theoretical maximum is 128.1 kgf at 1.0 MPa. Ports are 1/8" on both covers and the male rod thread is M12x1.25. The extend stroke can be trimmed by up to 50 mm via the external stop screw.
No. The bumper pads are fixed into the covers and simply decelerate the piston near each stroke end; they cannot be tuned. If the machine needs an adjustable air cushion, the MACJ family combines cushioning with the same style of adjustable-stroke stop screw.
