Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SU 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 MAC63X300SU
Heavy-duty strokes in a mini format: the MAC63X300SU delivers 63 mm of bore over a 300 mm travel, pushing 1557.9 N and pulling 1457.4 N at 0.5 MPa (72 psi). It is double acting, so air does the work in both directions, and the variable air cushion at each end absorbs the momentum of fast, heavy loads. Air supply runs 0.15-1.0 MPa (22-145 psi) with speeds from 30-800 mm/s.
The U flat-end back cover gives a compact fixed nose for bolt-through mounting in sliding doors, kickers and pushers. Inside, the two-way piston seal stores its own grease, cutting relube intervals on long travel cycles. Sized for real work rather than headline force, count on about 935 N at 0.5 MPa before derating - and for vertical jobs the rod lifts roughly 79 kg with a 2:1 safety margin. Position switches are plug-and-play: the magnet comes as standard, matched to CMSG, DMSG and EMSG sensors.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SU Is Used
Shuttle cart drive
Drives a 60-75 kg tote shuttle between two rack stations, using the flat-end cover for a clean fixed mount and external rails for guidance.
Indexing stop gate
Raises and lowers a stop gate on a rotary indexing table; the 300 mm stroke clears tall fixtures and the cushion quiets every cycle.
Mix vessel lid lift
Opens the lid of a 70 kg mixing vessel in a washdown food room, where the stainless round barrel outlasts painted-steel minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X300SU the Right Cylinder?
This is the strongest bore in the MA range - if the duty needs only 981 N push at 0.5 MPa, step down to the 50 mm MAC to cut air use. The 300 mm stroke is a standard length (the family tops out at 500 mm for this bore). Remember that a plain double-acting cylinder has no holding power: when the valve centres or air is lost, the rod coasts, so specify a rod lock or pilot check valve for a load that must not move.
Long 300 mm strokes magnify any side load, so carry the load in external guides and keep the 16 mm rod in pure tension or compression. Need pivoting instead of fixed mounting? The CA pivot or CM round-end back covers, plus FA, LB and SDB plates, are available on the same body.
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 MAC63X300SU FAQ
Push force 1557.9 N and pull force 1457.4 N at 0.5 MPa; at 0.7 MPa it is 2181.0 N push and 2040.3 N pull; theoretical maximum 317.7 kgf at 1.0 MPa. Bore 63 mm, stroke 300 mm (standard, max 500 mm), rod 16 mm with M14x1.5 thread, 1/4" ports, pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C.
No. The variable air cushion only decelerates the piston near each end of stroke - it never locks the rod. With the valve centred or the supply removed, the piston drifts under load. For a clamped or held position, add a rod lock cylinder or a pilot check valve in the line, and bleed the cushion needle screws gradually on first commissioning to tune the deceleration.
