Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 620mm 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.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM
A 620 mm reach makes the MAC32X620SCM one of the longest strokes AirTAC builds in the cushioned MAC mini family, still on a 32 mm bore. It is double acting with a variable air cushion at both ends, delivering 402 N push and 346 N pull at 0.5 MPa and 563 N at 0.7 MPa; sized for real work, that is roughly 241 N of continuous push before any margin is added.
Strokes beyond the 500 mm standard for this bore are manufactured to order, so confirm the exact barrel through AirtacDistr. Construction stays true to the MAC recipe: a riveted stainless-steel tube, a 20 um hard-chrome plated 12 mm rod and aluminium-alloy covers in a rolling-packed body. The CM round-end cover takes direct plate fixing, and the in-piston magnet (standard) reads CMSG, DMSG or EMSG switches. Operating window 0.15-1.0 MPa (22-145 psi); proof 1.5 MPa (215 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.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM Is Used
Checkweigher diverter
Lowering a pusher finger into a checkweigher lane: the 620 mm stroke reaches across two belts and the cushion stops the finger without jarring the load cell.
Cable-tensioning carriage
Tensioning flat cable on an assembly rig at a steady 240 N working force - well under the 402 N rating - keeps pull consistent through the full 620 mm pull-in.
Fume-hood sash assist
A laboratory fume hood sash glides on a 620 mm stroke; the stainless barrel shrugs off corrosive vapours near the hood face that corrode painted-steel minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM the Right Cylinder?
Force-wise, the neighbouring bores bracket this one neatly: a 25 mm MAC gives 245.3 N push at 0.5 MPa and a 40 mm MAC gives 628.3 N, so choose 32 mm when the duty lands between them. Vertically, 402 N translates to about 41 kg of lift, or 20 kg with a 2:1 margin - match your fixture weight against that figure. An unpressurised MAC neither holds nor brakes: the rod moves with the load, so add a rod lock for any suspended duty.
Fix with FA flange, LB foot or SDB bracket as the frame demands; the CM round-end cover here suits direct bolting. A 620 mm stroke magnifies buckling and side load, so guide the mass externally and keep thrust axial. Ports are 1/8", rod thread M10x1.25, PT standard with G and NPT selectable; the made-to-order stroke is confirmed by enquiry.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC32X620SCM FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa. Pressure range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, with air filtered to 40 um.
The CM round-end back cover bolts straight to a machine plate, and FA flange, LB foot or SDB pivot brackets can be added; I and Y rod knuckles suit the 12 mm M10x1.25 thread, and 1/8" ports take standard PT fittings with G or NPT selectable at order.
