Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 100mm stroke, 1/4" 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 MACJ50X100-100S
One cylinder, every stroke: with the trim window equal to the full 100 mm travel, the stop screw on this MACJ can set the extend stroke anywhere from a few millimetres up to 100 mm, so line changeovers need no cylinder swaps. The 50 mm bore pushes 981 N and pulls 881 N at 0.5 MPa and 1374 N at 0.7 MPa, double-acting with a variable air cushion at both ends. For duty planning, count on about 589 N of working force at 0.5 MPa, equivalent to lifting roughly 50 kg vertically once a 2:1 margin is applied.
The riveted round body - stainless tube, hard-chrome plated rod, rolled aluminium covers - keeps its seal and finish in wet or dusty plants where coated minis degrade. Because the magnet is built in as standard, CMSG, DMSG or EMSG switches mount straight onto the barrel for stroke-end detection. Pressure range is 0.15-1.0 MPa (22-145 psi) with speeds from 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X100-100S Is Used
Bottling guide rail lift
Raise guide rails on a bottling line when bottle formats change, setting exact lift height with the stop screw instead of changing hardware.
Tray transfer pusher
Push trays of jars sideways between conveyor lanes at a filling plant, with the cushion landing each tray without rattling the glass.
Latch life-test rig
Cycle a car door latch through 100 mm of actuator travel on a durability test bench, trimming the stroke to match each latch geometry.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-100S the Right Cylinder?
Below this model, a MACJ40 offers 628 N push at 0.5 MPa; above it, a MACJ63 reaches 1558 N - pick this bore when mid-range force and a fully trimmable 100 mm stroke are both needed. On a stroke this long, guide the load externally so side forces stay off the 16 mm rod. The trim screw marks the extend endpoint but holds nothing if air is lost, so do not treat it as a brake. FA flange or LB foot mounting plus I or Y knuckles for pivoting loads completes the setup, and the factory-fitted magnet accepts switches with no option ordering.
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 MACJ50X100-100S FAQ
At 0.5 MPa expect 981 N on push and 881 N on pull; at 0.7 MPa, 1374 N push and 1233 N pull, with a theoretical peak of 200 kgf at 1.0 MPa. The unit is double-acting with variable cushions at both ends, and the adjustable window spans the entire 100 mm stroke. It operates on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
It does not - the external stop only shortens the extend travel within the 100 mm window and acts as a mechanical end stop, so the piston can still drift if pressure drops. Sensing is covered instead by the standard built-in magnet, which takes CMSG, DMSG or EMSG switches without modification.
