Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 500mm stroke, 1/8" 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 MAC32X500SCMLB
Mounted on LB feet, this 500 mm stroke cylinder holds a 32 mm bore steady along a machine rail while delivering 402.2 N of push and 345.6 N of pull at 0.5 MPa. Needle-screw air cushions at both ends absorb the landing, so you can run 30-800 mm/s without cover damage.
Foot mounting spreads the thrust into the base plate - useful when a long rod pushes at an angle. The stainless round barrel with hard-chrome 12 mm rod shrugs off washdown, and the magnet fitted as standard takes CMSG, DMSG or EMSG switches for end-of-stroke signals. Because the pull stroke delivers only 345.6 N, about 35 kg of force at 0.5 MPa, size any retract-side work on that figure rather than the push.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X500SCMLB Is Used
Pallet stop and locate
Bolt the LB feet along a conveyor frame and stop pallets at a 500 mm pitch; 402 N of active push seats a rolling 200 kg pallet on level rollers.
Press-off ejector
Eject stamped blanks from a die shoe after the press opens; foot mounting resists the reaction while the cushion softens breakaway.
Batch counting gate
Swing a counting gate every cycle on a filling line; the magnet and DMSG switch log each stroke into the PLC.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SCMLB the Right Cylinder?
Compare before buying: the 25 mm bore pushes 245.3 N at 0.5 MPa for lighter gates, while the 40 mm bore reaches 628.3 N for heavier clamps - this 32 mm model sits between them at 402.2 N. Keep working loads near 241 N to leave margin for friction and pressure drop.
At 500 mm of stroke, side load is the main enemy of the 12 mm rod, so guide external slides or fit a rod knuckle and never let the load cantilever the rod. The LB feet bolt to a flat base and carry the bending moment of long pushes. If air drops, the rod simply drifts with the load - add a pilot check valve or rod lock where the position must be kept.
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 MAC32X500SCMLB FAQ
At 0.5 MPa this cylinder pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the figures are 563.0 N push and 483.8 N pull, with 82 kgf theoretical maximum at 1.0 MPa. The 32 mm bore takes 1/8 inch ports, runs 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, and the 12 mm rod threads M10x1.25.
LB feet bolt the barrel to a base plate and carry the side bending loads that a 500 mm stroke generates, which a plain back-cover mount cannot. The feet add no stroke and leave both ports and the magnet - standard, feeding CMSG, DMSG or EMSG switches - fully accessible for wiring and tubing.
