Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 300mm 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 MAC63X300SCA
Three hundred millimetres of stroke on the largest MAC bore gives the MAC63X300SCA real reach: 1557.9 N of push at 0.5 MPa against 1457.4 N of pull, double acting with a variable air cushion soaking up shock at each end. Push 0.7 MPa into it and the force climbs to 2181 N.
Covers are rolled onto the stainless tube rather than bolted, sealing the body with no through-bolts to loosen on vibrating machines. The hard-chrome plated rod and stainless bore resist the corrosion that kills painted minis in damp plants. As a planning rule, hold the working load near 935 N - about 60 percent of rated push at 0.5 MPa - or count on close to 79 kg of vertical lift at a 2:1 margin. CMSG / DMSG / EMSG switches read the standard magnet with nothing extra to buy.

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 MAC63X300SCA Is Used
Pallet wrapper squaring arm
Squares tall pallet loads before the turntable spins; 300 mm of travel covers a full stack face in one pass, backed by 1557.9 N at 0.5 MPa.
Screenings sluice gate
Rakes a wastewater screen channel clear on every cycle; the chrome-plated rod and stainless bore stand up to constant splash and grit.
Small-bale chamber door
Opens the chamber door of a farm baler; about 935 N of working push swings the heavy door and the end-of-stroke cushion catches its weight.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SCA the Right Cylinder?
The 50 mm bore pushes 981 N at 0.5 MPa and covers most light work; once real loads approach 900 N, this 63 mm barrel is the only step up - it tops the series. Remember a plain MAC drifts the moment air is lost, so a rod lock or pilot check valve is essential wherever the 300 mm stroke must park under load. The CA pivot cover suits clevis and link mounts, with FA flange, LB foot or SDB bracket options for frames, and the built-in magnet feeds CMSG / DMSG / EMSG sensors as standard. A 300 mm stroke is long for a mini cylinder - support and align the load well to keep bending loads off the 16 mm rod.
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 MAC63X300SCA FAQ
It delivers 1557.9 N push and 1457.4 N pull at 0.5 MPa, rising to 2181 N and 2040 N at 0.7 MPa, with 317.7 kgf as the theoretical maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, over a 300 mm stroke.
The CA pivot cover accepts a clevis or swing link directly for linkage motion. For fixed frames add an FA flange or LB foot, or an SDB pivot bracket for a centre support; I and Y rod knuckles cover the tooling side of the connection.
