The AirTAC MAC Stainless Steel Mini Air Cylinder MAC40X90SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 90mm 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.
For a 90 mm stroke of pushing and pulling, MAC40X90SCA delivers 628 N forward and 528 N back at 0.5 MPa within the 0.15-1.0 MPa (22-145 psi) supply band. The variable cushion at each end dials out impact so the covers last.
AirTAC rolls the aluminium covers and a stainless block onto the steel barrel, a sealed riveted joint that keeps the round body rigid without external hardware, so it survives damp plants far better than painted minis. The CA pivot back cover swings on a pin without extra brackets, and the built-in magnet means position switches (CMSG / DMSG / EMSG) mount straight on.

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 | 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.
| MAC | Standard round-body mini cylinder (double-acting, variable cushion). |
|---|---|
| 40 | Bore size in mm. |
| ×90 | Stroke length in mm. |
| -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 (double rod, 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.
Pivot pin mount flips cartons at a sorter junction; the cushioned stop keeps the flap from slamming even at 800 mm/s.
628 N forward engages the yoke and 528 N pull releases it; the magnet signals engaged position via a CMSG switch.
Size by force: a 32 mm MAC pushes 402 N at 0.5 MPa while the next size up, 50 mm, reaches 981 N - this 40 mm model's 628 N covers the gap for gates and lifters. It does not hold position on lost air; the piston will drift, so fit a pilot check valve or rod lock where a suspended load matters.
CA pivot mounting swings freely on a pin, and the standard magnet works with CMSG / DMSG / EMSG switches for end-of-stroke signals. Air ports are 1/8"; rod thread M12x1.25 on a 16 mm rod.
Quick checklist
The piston magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the 40 mm barrel and read end positions - no special-order piston required. Mount the CA pivot on a pin, add FA flange, LB foot or SDB brackets if the frame needs them, and plumb the 1/8" ports.
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa those climb to 879.6 N and 738.9 N, with 128.1 kgf theoretical maximum at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), rod 16 mm, rod thread M12x1.25, maximum standard stroke 500 mm.
