The AirTAC AirTAC MA25X150SCA Mini Cylinder 25 mm Bore CA Pivot is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 150mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Double acting through and through, the MA25X150SCA pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa across its 150 mm stroke, while fixed anti-impact bumper pads soften the arrival at each end of travel. Nudging supply up to 0.7 MPa lifts the push to 343.4 N, so a small regulator trim buys real force headroom without changing hardware. Its high-precision stainless barrel and hard-chrome plated rod (20 um) tolerate washdown and humid shop air far better than painted or plain-aluminium minis, and the rolled aluminium covers keep the round body short. For sizing, plan real work at about 147 N rather than the full 245.3 N rating - that reserve covers seal drag and pressure dips. A 25 mm bore lifts roughly 25 kg at 0.5 MPa, so halved for a 2:1 margin it safely handles vertical loads of about 12 kg.

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.

| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
With 245.3 N at 0.5 MPa and a 150 mm sweep, this cylinder knocks small cartons cleanly off a conveyor end stop at up to 800 mm/s.
The 150 mm stroke clears the jig for loading, then the 25 mm bore clamps workpieces with about 147 N of reliable working force.
After pressing, the rod pushes finished bushings out of the die pocket; the fixed bumper pads tame the return-stroke impact.
If 245.3 N at 0.5 MPa overshoots the task, the MA20 delivers 157.0 N in a slimmer 20 mm barrel; when demands grow, step up to the MA32 and gain 402.2 N at the same pressure. The CA pivot back cover bolts straight to a clevis so the rod can follow slight misalignment; switch to an FA flange or LB foot if the barrel itself needs fixing. Note the MA drifts freely the instant air is removed - no internal lock exists - so add a pilot check valve or rod lock wherever a mid-stroke load must stay put. The magnet comes built in as standard, letting CMSG or DMSG switches clip on for end-of-stroke detection without any special-order piston.
Quick checklist
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the push is 343.4 N and the theoretical maximum is 50 kgf at 1.0 MPa. The bore is 25 mm, the rod is 10 mm with an M10x1.25 male thread, the port is 1/8, the stroke is 150 mm (within the 500 mm standard range), and the CA pivot back cover suits clevis mounting.
No. The MA25X150SCA carries fixed anti-impact bumper pads that simply decelerate the piston at stroke end - they cannot be tuned. Adjustable air cushioning belongs to the MAC family instead. Also keep in mind the piston holds nothing on air loss, so use a rod lock or pilot check valve where a load must stay parked.
