The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X160-75S 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.
The 75 mm trim window on this MACJ32X160-75S means one unit can serve several fixture depths - trim it down from the full 160 mm with a screwdriver instead of stocking three fixed-stroke cylinders. Double-acting with variable cushions at each end, it runs 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s, reaching 402 N push at 0.5 MPa.
AirTAC builds it as a round-body mini: stainless barrel rolled against aluminium-alloy covers, a 12 mm rod hard-chrome plated to 20 um, and the magnet already fitted for CMSG, DMSG and EMSG switches. For sizing, count on about 241 N of usable push at 0.5 MPa once a healthy margin is kept - that suits clamps, diverters and light presses alike.

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.
| MACJ | Standard round-body mini cylinder (adjustable-stroke, variable cushion). |
|---|---|
| 32 | Bore size in mm. |
| ×160 | Stroke length in mm. |
| -75 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
Kicks parcels between conveyor lanes on a sortation line; the wide 75 mm window lets maintenance re-tune throw length per lane without changing cylinders.
One clamp model now serves several jigs on a machining fixture, with the trim window set per jig and the air cushions damping each clamping move.
Pushes cartons square before strapping at a palletizing cell, where cushion tuning prevents carton bounce even at full line speed.
A bore-25 MA pushes 245 N at 0.5 MPa, leaving about 147 N of practical work - light duty; if 402 N feels short, bore 40 gives 628 N in the same family. The stop screw trims extend only and will not hold a load against air loss, so add a valve or external stop where position must persist. Choose FA flange or LB foot for the body and I or Y knuckle for the rod end, and on a 160 mm stroke mind side load against the 12 mm rod.
Quick checklist
Push is 402 N and pull 346 N at 0.5 MPa; at 0.7 MPa expect 563 N push and 484 N pull; theoretical maximum 82 kgf at 1.0 MPa. It accepts 0.15-1.0 MPa (22-145 psi), runs 30-800 mm/s, and breathes through a 1/8 inch port.
Yes - every MACJ ships with the piston magnet as standard, so CMSG, DMSG and EMSG switches clip straight onto the 32 mm barrel with no special-order piston. Combined with the adjustable stroke, you get both a tunable stop position and electrical end detection.
