The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X60-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 60mm stroke, 1/4" 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.
Fine positioning is the point of the MACJ63X60-10S: its stop screw trims the 60 mm extend stroke down by up to 10 mm, letting you dial the end point in millimetre steps after the machine is assembled. The cylinder is double-acting with a variable air cushion at each end, and every unit ships with a magnet already seated in the piston, so CMSG, DMSG and EMSG switches clip on as standard hardware rather than a paid option.
Force at 0.5 MPa reads 1558 N pushing and 1457 N pulling, rising to 2181 N and 2040 N at 0.7 MPa, with 317.7 kgf as the theoretical ceiling at 1.0 MPa. Roughly 935 N of the 0.5 MPa push is a sensible working budget. The stainless barrel and chrome-plated carbon-steel rod keep corrosion out of wet cells; supply 0.15-1.0 MPa (22-145 psi) and run between 30-800 mm/s.

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.

| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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.
The standard magnet drives a CMSG switch to confirm full extension before the robot advances, and the 10 mm trim lets you match the end point to varying tray depths.
Each filler lane dips to a slightly different height; the stop screw is turned until the nozzle seats correctly, no shims or cylinder swaps needed.
1558 N of push folds stiff double-wall flaps, while the dual air cushions absorb the shock of fast tuck cycles at the top of the 30-800 mm/s speed range.
Compare frames before ordering: bore 50 delivers 981 N push at 0.5 MPa and suits loads under roughly 580 N of work, while bore 63 tops the MA line at 1558 N. If a fixed stroke fits the job better than a trimmable one, the MAC63 covers the same force class, and the MACD double-rod version adds a rod at each end. Remember the 10 mm adjuster sets the extend endpoint only - it is an end stop, so the rod will still coast or sag if pressure drops. Mount via FA flange or LB foot, add I or Y rod knuckles for the linkage, and you are done.
Quick checklist
Push is 1558 N and pull 1457 N at 0.5 MPa; at 0.7 MPa expect 2181 N push and 2040 N pull; the theoretical peak is 317.7 kgf at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi).
No. The magnet is built into every MA piston as standard, so CMSG, DMSG or EMSG reed and Hall switches mount directly on the stainless barrel and read stroke position immediately.
