Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 50mm 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 MAC50X50SCM
The MAC50X50SCM pairs the strongest 50 mm MAC force class - 981 N push and 881 N pull at 0.5 MPa, 1374 N at 0.7 MPa - with a round-end CM rear cover that seats into machined pockets for a tight, bracket-free mount. Air drives the piston both ways and twin variable cushions soften each end of travel.
Its stainless rolled barrel and hard-chrome 16 mm rod hold up in humid shops and light chemical splash where painted bodies swell and flake. The operating band is 0.15-1.0 MPa (22-145 psi) with 30-800 mm/s speed. Count on about 589 N of working force at 0.5 MPa, enough to lift roughly 50 kg vertically with a 2:1 safety factor; the standard magnet feeds CMSG / DMSG / EMSG switches with no special-order piston.

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 MAC50X50SCM Is Used
Bench press bushing ram
Presses small bushings into housings on an assembly bench; about 589 N of practical working force at 0.5 MPa suits light interference fits without distortion.
Lift table corner ram
Raises one corner of a small die-change table; the round-end CM cover seats into a machined pocket and roughly 50 kg can be lifted vertically at a 2:1 margin.
Sample fatigue loader
Applies repeatable 981 N compressive cycles to test coupons; twin cushions soften each reversal and speed can sit anywhere in the 30-800 mm/s window.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SCM the Right Cylinder?
A 40 mm MAC gives 628 N at 0.5 MPa and a 63 mm gives 1558 N - pick the size the load actually needs. The CM round-end back cover mounts clean against a fixed plate, and SDB pivot or FA flange brackets are available if the frame requires them. Because both chambers exhaust when the valve centres, the rod is free to move, so never rely on the cylinder alone to hold position; add a pilot check valve or rod lock. With only 50 mm of stroke, side load on the 16 mm rod stays low, but alignment still matters on press-style uses.
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 MAC50X50SCM FAQ
50 mm bore, 50 mm stroke, 16 mm hard-chrome rod, 1/4" ports, M14x1.5 rod thread. Double-acting push 981 N and pull 881 N at 0.5 MPa; 1374 N push and 1233 N pull at 0.7 MPa; theoretical max 200 kgf at 1.0 MPa; speed window 30-800 mm/s; operating band 0.15-1.0 MPa (22-145 psi).
The round-end CM cover seats neatly into machined pockets or clamps, keeping the envelope tight, while the twin variable cushions let you bleed off end-of-stroke impact - useful when cycling a ram at the faster end of the 30-800 mm/s range. Back the needle screws off at first run, then close them in steps until the stop sounds clean.
