Airtac MARU Stainless Steel Mini Cylinder MARU63X50S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X50S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm 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 MARU Stainless Steel Mini Cylinder MARU63X50S
Short stroke, heavy hitting - the MARU63X50S turns just 50 mm of travel into 1557.9 N of push at 0.5 MPa, or 2181.0 N when fed 0.7 MPa. The up bracket is rolled into the riveted front cover as part of the body itself, so mounting is a two-bolt job with no separate foot or flange to purchase.
That 0.5 MPa rating works out to about 935 N of practical force - around 79 kg lifted vertically at a 2:1 margin - which suits clamps, kickers and staking heads. The magnet comes built in for CMSG, DMSG or EMSG switches, and the 1/4 inch ports feed the 63 mm bore quickly enough for its full 30-800 mm/s speed band on 0.15-1.0 MPa (22-145 psi) filtered air.

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 MARU Stainless Steel Mini Cylinder MARU63X50S Is Used
Fixture clamp on a CNC milling vise
The 63 mm bore clamps aluminium blanks before milling; 935 N of working force holds the part without crushing it.
Staking head on a lab sample press
Short 50 mm travel and 2181.0 N at 0.7 MPa seat sensors into housings on a bench-top staking station.
Kicker on a pharmaceutical cartoner
The cushioned 50 mm kick diverts blister packs between chute lanes at production speed, with sensor feedback from the standard magnet.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X50S the Right Cylinder?
If 50 mm of travel is all the fixture allows, stepping up from the 50 mm bore size (981.3 N push at 0.5 MPa) to this 63 mm model buys roughly 577 N more thrust - useful on stiff clamps and interference fits. A plain MAR cannot hold a clamp closed if the air drops; the piston will move, so use a rod lock or a mechanical latch where that matters. The M14x1.5 rod thread takes I and Y knuckles, and the operating temperature spans -20 to +70 C.
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 MARU Stainless Steel Mini Cylinder MARU63X50S FAQ
Push at 0.5 MPa is 1557.9 N against 1457.4 N on retract; at 0.7 MPa the numbers climb to 2181.0 N and 2040.3 N. The theoretical maximum stands at 317.7 kgf at 1.0 MPa. The 63 mm bore drives a 16 mm hard-chrome rod with 1/4 inch ports over a 50 mm stroke.
No. The magnet is built into the piston as standard on every MA-series cylinder, so a CMSG, DMSG or EMSG switch simply clips to the barrel groove and signals end of stroke - no special-order piston or late retrofit needed.
