Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 175mm 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 MAC63X175SU
Nothing in the MAC catalogue out-pushes a Dia 63 bore. Give this 175 mm cylinder 0.5 MPa and the rod carries 1557.9 N forward, 1457.4 N back; near full rated supply the thrust climbs to 2181.0 N at 0.7 MPa. Air drives both directions - there is no spring in the barrel.
The U flat-end cover gives you a flat, machined mounting face that bolts flush against machine plates without an intermediate bracket, an option the CA and CM covers do not offer. Inside, the rolled stainless tube resists the condensation found around dye vats and outdoor conveyors. Vertical lifting check: a 1557.9 N push equals the weight of about 159 kg, so halving that for a 2:1 margin lets you raise roughly 79 kg of dead load at 0.5 MPa.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MAC63X175SU Is Used
Bag layer pusher
Shifts 70 kg layers of feed sacks 175 mm from the bagging conveyor into a transfer car, with cushioned stops protecting the stack at both ends.
Dairy vat lid actuator
The riveted stainless barrel survives daily caustic washdown in the cheese plant while lifting a 75 kg domed lid clear of the 500 L vat.
Chip conveyor gate drive
Slides a heavy interlocked gate on a CNC chip conveyor closed against swarf build-up; the flat U cover bolts straight to the guard frame.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SU the Right Cylinder?
The 50 mm bore's 981.3 N at 0.5 MPa may already do the job - step to Dia 63 only when that falls short. Mount through the flat face of the U cover, or add an FA flange or LB foot; the SDB pivot bracket suits swinging links. A centred valve or dropped supply leaves the rod free - position holds only while air holds the piston - so a rod lock or pilot check valve protects suspended loads. Runs on 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s; keep guide rails on the load so the 16 mm rod sees thrust alone.
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 MAC63X175SU FAQ
Push at 0.5 MPa is 1557.9 N and pull is 1457.4 N; at 0.7 MPa the piston generates 2181.0 N forward and 2040.3 N back. The Dia 63 bore tops out at 317.7 kgf theoretically at 1.0 MPa. Supply ports are 1/4" and the rod thread is M14x1.5.
It provides a machined flat face at the rear cover, so the cylinder bolts flush against a machine plate with no intermediate bracket. Combine it with an FA flange or LB foot when the frame needs a different anchor, and rely on the built-in magnet - standard on every unit - to carry CMSG, DMSG or EMSG position switches.
