Airtac MAC Stainless Steel Mini Air Cylinder MAC50X325SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X325SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 325mm 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 MAC50X325SCA
Long travel and mini-cylinder size rarely meet, yet the MAC50X325SCA delivers 325 mm of stroke from a 50 mm stainless round barrel - well inside the 500 mm standard limit for this bore. It is double acting, cushioned variably at each end, and pushes 981 N at 0.5 MPa (1374 N at 0.7 MPa) through 1/4" ports on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
At this stroke the 16 mm hard-chrome rod is the part to respect: keep side loads off the rod and guide the load on linear bearings, because rod bending - not raw force - is what usually fails a long mini cylinder. Vertically, the 0.5 MPa push equals about 100 kgf, so halving for margin still leaves roughly 50 kg of lift capacity. The CA pivot eye at the rear suits swing or trunnion duty across the full travel.

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 MAC50X325SCA Is Used
Sliding door drive
Opens a 300 mm machine guard door on a CNC cell, cushion screws eased for a soft stop.
Deep-drawer ejector
Pushes loaded parts drawers fully out of a storage magazine in one 325 mm move.
Cross-belt diverter
Swings a diverter arm across a parcel conveyor lane at a sortation hub.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X325SCA the Right Cylinder?
A 40 mm bore at 628 N is the lighter choice; the 63 mm bore (1558 N) suits heavier transfer strokes. Mount with FA flange or LB foot for straight pushes, or keep the CA pivot for swinging motion - SDB pivot brackets are also available. Sensor-ready by default: the standard piston magnet drives CMSG / DMSG / EMSG switches along the 325 mm travel. Air off means drift, so a rod lock or pilot check valve is the answer for held loads.
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 MAC50X325SCA FAQ
At 0.5 MPa the 50 mm bore gives 981 N push and 881 N pull; at 0.7 MPa it is 1374 N push and 1233 N pull; the theoretical maximum at 1.0 MPa is 200 kgf. The force stays constant along the full 325 mm of travel.
Support the load externally and align the thrust with the rod - side loading bends the 16 mm rod over a 325 mm travel. The rear CA pivot suits swinging motion, while FA flange and LB foot options anchor straight pushes.
