The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X100-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 100mm 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.
For small grippers and part presenters that need a touch of tuning, the MACJ16X100-10S pairs a 16 mm stainless barrel with a 100 mm stroke whose extend position can be trimmed anywhere within a 10 mm window using the built-in stop screw. Double-acting throughout, it develops 100.5 N pushing and 86.4 N retracting at 0.5 MPa, rising to 140.7 N of push at 0.7 MPa. Both ends carry a variable air cushion, so a 30-800 mm/s cycle can land without hammering the rolled aluminium covers.
Work to roughly 60 N of continuous push at 0.5 MPa and this 6 mm rod stays comfortable; the same rating means lifting about 5 kg vertically with a 2:1 margin. The hard-chrome plated carbon-steel rod shrugs off washdown splash far better than painted minis, and the magnet fitted as standard lets CMSG, DMSG or EMSG switches clip straight onto the barrel with no special-order piston. Supply filtered air at 0.15-1.0 MPa (22-145 psi).

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.
A 60 N working push at 0.5 MPa cleanly ejects filled counting trays, while the 10 mm trim lets operators shorten the extend stroke so each tray lands exactly at the capping position.
The rating is good for about 5 kg of vertical lift with a 2:1 margin, so raising loaded vial racks between wash and assay stations stays smooth, and the variable cushions stop the rack from jolting at the top.
Pivoting a product flap between two chutes suits the 100 mm travel and 100.5 N output; the stainless barrel and chrome rod stand up to daily wipe-downs in food areas.
The 16 mm bore is the smallest in the MA family; if 100.5 N at 0.5 MPa feels marginal, step up to the MACJ20 (157.0 N) or MACJ25 (245.3 N) rather than running near the ceiling. FA flange and LB foot mountings, plus I and Y rod knuckles, cover most fixturing layouts. Treat the stroke adjuster purely as an extend-side end stop - if air drops, the rod can still drift back, so it will not hold a load in position. With a 6 mm rod over 100 mm of travel, keep side loading minimal or guide the load externally.
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. The theoretical maximum at 1.0 MPa is about 20.5 kgf. Air port is M5x0.8 and the rod thread is M6x1.0.
No. Every MA-series cylinder carries a built-in magnet as standard, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel for end-of-stroke confirmation, with no special-order piston and no waiting on a custom build.
