Airtac MAC Stainless Steel Mini Air Cylinder MAC50X40SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X40SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 40mm 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.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X40SCAH
A 50 mm bore in a riveted stainless round barrel, a 40 mm stroke and a trailing H build code: the MAC50X40SCAH follows the standard MA recipe (CA pivot rear cover, double-acting piston, variable air cushion at both ends), but the H suffix is not one of the standard MA option letters, so confirm its exact meaning from the datasheet before ordering. What stays certain is the force class - 981 N push and 881 N pull at 0.5 MPa (72 psi), climbing to 1374 N at 0.7 MPa.
Treat about 589 N as the continuous work rating, or 60 percent of the 0.5 MPa (72 psi) push, and this bore-50 unit will outlast cheap painted minis in wet or dusty cells thanks to the stainless tube and hard-chrome 16 mm rod. The piston magnet is standard, so CMSG, DMSG or EMSG switches fit for stroke-end detection without a special-order build.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X40SCAH Is Used
Toe clamp on a CNC fixture plate
Pulling a hold-down toe clamp across a CNC fixture plate; 40 mm covers the clamp throw and 981 N at 0.5 MPa (72 psi) seats it hard against cutting forces.
Load head on a spring test rig
Driving the load head of a small spring-test bench, where the rear pivot keeps the head self-aligned and a DMSG switch brackets the 40 mm measurement window.
Slide gate on a grain doser
Opening and closing a grain-doser hopper gate between batches; the stainless barrel shrugs off dust and the periodic wash-down hygiene rounds.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X40SCAH the Right Cylinder?
Short-stroke and strong, this bore-50 unit sits between the 628 N bore-40 MAC and the 1558 N bore-63 MAC at 0.5 MPa (72 psi), so downsize when force is ample and upsize when your clamp needs margin. Mount on the CA pivot rear cover with an I or Y rod knuckle for linkage work, or add FA flange and LB foot brackets for a fixed frame. If the load must hold with air off, remember the cushion is a shock damper rather than a lock - fit a rod lock or pilot check valve to the circuit. Air ports are 1/4 inch PT.
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 MAC50X40SCAH FAQ
At 0.5 MPa (72 psi): 981 N push and 881 N pull. At 0.7 MPa: 1374 N push and 1233 N pull, with a theoretical peak of 200.1 kgf at 1.0 MPa. Stroke is 40 mm on a 16 mm rod with 1/4 inch PT ports; supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, fluid air filtered to 40 um.
It is not one of the standard MA suffix letters (S magnet, CA, U or CM rear cover, FA, LB or SDB mounts), so confirm the exact variant from the datasheet before ordering. The base build is nonetheless fixed: double acting, variable air cushion at both ends, stainless round barrel with aluminium covers, and a standard piston magnet.
