Airtac MAC Stainless Steel Mini Air Cylinder MAC50X165SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X165SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 165mm 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 MAC50X165SCM
The extra 165 mm of travel on the MAC50X165SCM covers longer passes - full-width gates, deep fixtures, wide divert lanes - while the body stays a compact riveted round of stainless tube and rolled aluminium covers. Double acting with variable air cushions at both ends, the 50 mm bore puts out 981 N of push and 881 N of pull at 0.5 MPa (72 psi), and 1374 N at 0.7 MPa (102 psi).
Plan real work around about 589 N at 0.5 MPa (72 psi), the de-rated figure behind the 981 N rating. Upright, the raw force lifts roughly 100 kg; halve it for a 2:1 margin and the cylinder raises about 50 kg. On a stroke this long, keep side loads off the 16 mm rod or guide them externally - bending, not thrust, is what shortens the life of long-stroke minis. The CM round-end cover takes pivot pins directly, and the standard magnet accepts CMSG, DMSG or EMSG switches.

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 MAC50X165SCM Is Used
Mixer discharge door
Opening the discharge door of a small ribbon mixer: 165 mm of travel clears the outlet fully, and 981 N at 0.5 MPa (72 psi) shears past compacted powder without stalling.
Stretch wrapper arm drive
Driving the film clamp arm of a pallet stretch wrapper: the end cushions quiet the arm's return, and an EMSG switch on the built-in magnet times the cut-and-tuck sequence.
Scrap chute kicker
Kicking offcuts out of a punch press scrap chute: the stainless barrel stands up to oily swarf, and the 165 mm throw clears the chute mouth completely on every stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X165SCM the Right Cylinder?
Downsizing to 40 mm costs you force (628 N at 0.5 MPa (72 psi)); upsizing to 63 mm buys 1558 N. Between them, this 50 mm bore handles medium tooling with reserve. Position is not remembered: cut the air and the rod drifts under load, so a rod lock or pilot check valve belongs in any circuit that parks a weight. Mount with FA flange, LB foot or SDB bracket, align the 165 mm stroke with the load line, run the cushion needles from fully open to a firm but gentle stop through the 30-800 mm/s range, and let the built-in magnet feed CMSG, DMSG or EMSG switches.
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 MAC50X165SCM FAQ
Push at 0.5 MPa (72 psi) is 981 N with 881 N of pull; at 0.7 MPa (102 psi) push reaches 1374 N and pull 1233 N; peak theoretical at 1.0 MPa (145 psi) is 200 kgf. Stroke 165 mm, rod 16 mm, male thread M14x1.5, ports 1/4 inch, operating pressure 0.15-1.0 MPa (22-145 psi).
No. Bores 16-63 mm are catalogued to 500 mm of standard stroke, so 165 mm is a shelf item. The order code reads MAC50X165SCM: 50 mm bore, 165 mm stroke, magnet fitted as standard, CM round-end back cover, PT thread ports.
