Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X60-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X60-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 60mm 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 MACJ50X60-30S
Compact 60 mm stroke, full 50 mm bore: this cylinder packs 981.3 N of push at 0.5 MPa into a body barely longer than its travel. A 30 mm stop-screw window trims the extend stroke on site, and dual variable cushions keep 30-800 mm/s cycles quiet at both ends.
The riveted stainless round barrel with its hard-chrome plated rod tolerates splash and humidity that would rust painted minis, and the built-in magnet (standard) accepts CMSG / DMSG / EMSG switches out of the box. For load planning, count on about 589 N of practical push at 0.5 MPa - good for roughly 50 kg of vertical lifting with a 2:1 margin.

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 MACJ50X60-30S Is Used
Bench punch hold-down clamps
Clamping aluminium blanks before a light bench punch; 981 N at 0.5 MPa holds sheet flat without marking, and the 30 mm window tunes clamp travel.
Robot gripper backup stops
Acting as a mechanical home stop for a pick arm, with a DMSG switch signalling the seated position via the standard magnet.
Fixture indexing pins
Plunging indexing pins into a welding fixture table; the short stroke and cushion keep location repeatable at high cycle rates.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X60-30S the Right Cylinder?
Forces frame the choice: the 40 mm bore gives 628.3 N at 0.5 MPa, this 50 mm gives 981.3 N, and the 63 mm gives 1557.9 N - a clamp needing near 1000 N lands here. Ports are 1/4 inch and rod thread is M14x1.5 with a 16 mm rod. The 30 mm adjuster is a stroke stop, not a load lock; on air loss the rod can still move, so use pilot-checked valves for holding. FA flange or LB foot mounting, with I / Y knuckles where the load articulates.
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 MACJ50X60-30S FAQ
Push is 981.3 N and pull is 880.8 N at 0.5 MPa; at 0.7 MPa expect 1373.8 N and 1233.1 N. Maximum theoretical output is 200.1 kgf at 1.0 MPa. The cylinder runs on 0.15-1.0 MPa (22-145 psi) and withstands 1.5 MPa (215 psi) proof.
Independent cushion screws at each end meter the exhaust air, so you can soften landing shock separately for extend and retract. Combined with the 30 mm stroke trim and speeds up to 800 mm/s, this lets heavier loads stop gently without metal-to-metal impact on the aluminium covers.
