Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MACJ32X300-75S
A wide 75 mm trim window makes the MACJ32X300-75S the flexible pick when the final extend position is not fixed at design time. AirTAC builds it double-acting with a variable air cushion at both ends, in a riveted round-body format: stainless barrel, aluminium-alloy covers, hard-chrome 12 mm rod. The 32 mm bore yields 402 N on extend at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) supply range.
Output-wise the bore sits between the 245 N of a 25 mm mini and the 628 N of a 40 mm unit, and its 82 kgf theoretical peak at 1.0 MPa leaves headroom for pressure spikes. Practical extend work should be sized near 241 N - roughly six tenths of the 402 N rating - so cushioning and friction never push the seal set past its comfort zone. CMSG, DMSG or EMSG switches can be clipped on at any time because the piston magnet is factory-fitted.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X300-75S Is Used
Assembly shuttle
Carries a small housing between two assembly stations on a 300 mm rail; 402 N extend at 0.5 MPa accelerates the carrier briskly.
Tote pusher
Pushes totes sideways off a picking line into a chute; the 75 mm trim lets a technician tune the park position right on the floor.
Sample rack lift
Raises sample racks in a lab automation module; the 402 N rating clears a 20 kg rack vertically while keeping the margin wide.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-75S the Right Cylinder?
Sizing check: retraction delivers 345.6 N at 0.5 MPa - enough for return springs up to that level - and extension reaches 402 N; if the load needs more, the 40 mm MACJ class offers 628 N. Over 300 mm of travel, support long workpieces or add an external guide so the 12 mm rod sees pure axial force. Mounting options are the FA flange and LB foot, with I or Y knuckles on the rod; remember the adjustable variant carries no SDB or back-cover code. The trim screw sets position, not holding force - under air loss the rod can still be pushed back.
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 MACJ32X300-75S FAQ
Count on 402.2 N extending and 345.6 N retracting at 0.5 MPa, rising to 563.0 N on extend at 0.7 MPa; theoretical peak output is 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and the cylinder cycles from 30 to 800 mm/s.
The MAC series is the fixed-stroke, cushioned sibling; this MACJ adds a stop screw that shortens the extend stroke by up to 75 mm after installation. If the layout changes, you adjust the stop rather than reorder the cylinder - useful in pilot lines and retooled fixtures.
