The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X160-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 160mm 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.
Trim up to 100 mm off the extend stroke and the MACJ32X160-100S adapts to fixtures that change between product sizes without swapping cylinders. The 32 mm double-acting bore pushes 402 N and pulls 346 N at 0.5 MPa; at 0.7 MPa those become 563 N and 484 N, with a theoretical ceiling of 82 kgf at 1.0 MPa. Both ends carry a variable air cushion, useful when the shortened stroke still runs at up to 800 mm/s.
Sealing and alignment come from the rolled construction: a stainless round barrel, hard-chrome plated 12 mm rod and aluminium covers riveted into one sealed body, with no painted surfaces to flake in wet areas. The magnet is built in, so CMSG / DMSG / EMSG switches detect position out of the box. In practice, hold continuous loads to about 241 N at 0.5 MPa, and for vertical work the push force equates to about 41 kg, or near 20 kg keeping 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.
| 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.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Stacking trays of two heights on a packaging line needs both the 160 mm full lift and the 100 mm short lift; one cylinder covers both via the stop screw.
402 N slides an aluminium safety door across a machine opening, with the 100 mm trim matching shorter door panels and the cushion damping each close.
Press splices to a set depth on wire-harness benches; the wide 100 mm window covers different crimp tooling heights without changing the actuator.
The 25 mm MACJ tops out at 245 N push and the 40 mm bore offers 628 N, so this mid-size 32 mm unit suits loads in between at its 160 mm stroke, which is standard for the bore. Guide any long or overhanging tooling externally to keep bending off the rod. The stop screw sets a shorter extend position and does not act as a brake: with air off the piston can still drift. Order FA flange or LB foot, choose I or Y knuckles for pivoting loads, and the standard magnet pairs with CMSG / DMSG / EMSG switches for sensing.
Quick checklist
Yes: 402 N push and 346 N pull at 0.5 MPa, 563 N push and 484 N pull at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. Stroke is 160 mm, adjustable down by up to 100 mm, with 1/8" ports, 30-800 mm/s speed and 0.15-1.0 MPa (22-145 psi) operation.
The stainless barrel, aluminium covers and stainless block are rolled together into one sealed body, so alignment stays true and there are no fasteners to work loose under vibration. Combined with the hard-chrome 12 mm rod, the unit resists corrosion in damp or washed-down areas far better than painted mini cylinders.
