The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 500mm 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.
At the far end of its standard stroke list, the MAC40X500SU sweeps 500 mm while pushing 628 N and retracting with 528 N at 0.5 MPa. Both directions are air powered, and an independent cushion at each port end absorbs deceleration energy, keeping motion smooth across the 30-800 mm/s band.
The U flat-end back cover presents a flat face that seats straight onto machine plates, no brackets required. Ports are 1/8 inch PT on this bore, and the factory-fitted piston magnet pairs with CMSG, DMSG and EMSG reed switches out of the box. For duty planning, treat about 377 N as the practical continuous push - roughly a 32 kg vertical lift at half the stall force.

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.

| ×500 | 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 (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.
Swinging a 500 mm lane divider on an outgoing pallet line, the cushions easing the plate onto its stop every cycle.
Raising hinged lids on small stainless mix tanks in a washdown dairy corner, where the hard-chrome rod resists daily hose-down.
Feeding a 400 mm indexing slide on an assembly bench; EMSG switches on the barrel confirm home and end via the standard magnet.
The 32 mm bore tops out near 402 N at 0.5 MPa and the 50 mm bore reaches 981 N, so pick by load rather than by price. Remember the rod freewheels the moment supply air is lost; a pilot check valve or rod-lock variant is the answer for suspended loads. The flat-end cover pairs naturally with LB foot or FA flange mounts if the body itself must be secured. With a 16 mm rod over 500 mm of stroke, align the load axially or add external guides to avoid rod bending.
Quick checklist
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa expect 879.6 N and 738.9 N. Maximum theoretical output reaches 128.1 kgf. Operating window is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi).
Yes - every MAC ships with the piston magnet already installed at no extra order step. CMSG, DMSG and EMSG switch series clamp onto the stainless barrel for end-of-stroke or mid-stroke signalling, and their position can be slid and re-tightened at any point along the 500 mm travel.
