The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 175mm stroke, M5×0.8 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.
A 16 mm bore MACJ with a 175 mm stroke and a 10 mm extend-trim window: the stop screw shortens the out-stroke on site anywhere inside that 10 mm band, and a variable air cushion at each end takes the sting out of end-of-stroke impact. Output is modest but real - 100.5 N of push at 0.5 MPa (140.7 N at 0.7 MPa) with 86.4 N on retract. Keep working loads near 60 N and the cylinder will still lift a 5 kg part vertically with a 2:1 margin.
Its stainless round barrel and 20 um hard-chrome rod handle washdown and humid air better than painted minis, while the rolled aluminium covers keep the body sealed for life. The magnet is fitted as standard, so CMSG, DMSG or EMSG switches snap on without any special-order piston.

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 | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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.
Indexing glass vials one station at a time on a small pharmaceutical filling rig, where the 10 mm trim dials in exact station spacing and the 5 kg-class lift margin covers lightweight carriers.
Tucking side flaps on small cosmetic cartons at up to 800 mm/s, with the dual cushion stopping the 100.5 N push from cracking the board at end of stroke.
Sliding a microplate between two lab assay positions over 175 mm; the stainless round body shrugs off repeated bench wipe-downs where painted minis would pit.
Output: 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N and 120.9 N at 0.7 MPa. If that is short, the 20 mm bore delivers 157 N at the same pressure; there is nothing smaller than 16 mm in this family. Remember the adjuster is purely an extend-side end stop - on air loss the rod still drifts, so do not count on it to hold a load. Ports are M5x0.8; pick FA flange, LB foot or an I / Y rod knuckle, and trim travel between 30 and 800 mm/s.
Quick checklist
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N, with a theoretical peak of 20.5 kgf at 1.0 MPa. Bore is 16 mm with a 6 mm rod, the port is M5x0.8 and the rod thread M6x1.0. The extend stroke trims within a 10 mm window, operating pressure spans 0.15-1.0 MPa (22-145 psi), and speed runs 30-800 mm/s.
Yes - every MACJ carries a built-in magnet as standard equipment, so CMSG, DMSG or EMSG switches mount directly on the barrel for end-of-stroke or mid-travel detection with no special-order piston required.
