The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X150-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 150mm 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.
Need 150 mm of travel that can also be dialled down to a fraction of that? The MACJ40X150-100S is a double-acting 40 mm mini cylinder whose extend stroke trims across a full 100 mm window, backed by variable air cushioning at both ends. Its riveted stainless barrel and 20 um hard-chrome rod take mild corrosion and washdown in stride - a real advantage in food, outdoor or humid plants. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Output at 0.5 MPa (73 psi) is 628 N push and 528 N pull; budget about 377 N for real work, or a vertical lift near 32 kg at a 2:1 ratio. Maximum theoretical force is 128 kgf. Magnet comes fitted as standard, so CMSG, DMSG and EMSG switches are a clip-on job. The trim screw defines where the extend stroke ends - it is not a brake, and the rod will move if supply air fails.

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.

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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.
Pushes parcels off a 400 mm wide conveyor lane; 150 mm travel crosses the belt and the 100 mm trim adapts to lane changes.
Swings a wash-line gate between two stations, the stainless barrel resisting washdown and humidity shift to shift.
Sweeps a formed carton layer off a stacking table, 628 N clearing rows easily at 0.5 MPa.
At this length, size carefully: the 32 mm bore would give 402 N at 0.5 MPa and the 50 mm bore 981 N, while this 40 mm body makes 628 N. The wide 100 mm window means one cylinder can serve several product sizes on the same station. Long strokes need external guidance - side loads will bend the 16 mm rod, so run the payload in slides or bushings. FA flange or LB foot mounts, I/Y knuckles, and a standard magnet for CMSG/DMSG/EMSG switching. The trim screw is not a load brake.
Quick checklist
At 0.5 MPa (73 psi): 628 N extend, 528 N retract. At 0.7 MPa: 880 N and 739 N. Maximum theoretical force 128 kgf at 1.0 MPa. The stroke adjusts across a 100 mm window; pressure range 0.15-1.0 MPa (22-145 psi); speed 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere inside the 100 mm window, so one cylinder covers multiple product sizes. It sets the end of travel only - it is not a mid-stroke lock, and the rod can drift if air pressure is lost.
