About the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA40X25SCA
The top of the MA range packs real clamping muscle into a compact round body: at 628.3 N push and 527.8 N pull on a 0.5 MPa (22-145 psi supply class) line, this 40 mm bore, 25 mm stroke double acting cylinder takes on work that smaller minis cannot. A fixed anti-impact bumper pad softens the short stroke ends, and the piston carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches mount straight onto the stainless barrel with no special piston order. Practically, plan on roughly 377 N of usable working force at 0.5 MPa rather than the full rating; halved again for a 2:1 margin, that means the rod lifts about 32 kg vertically. The hard-chrome plated 16 mm carbon-steel rod inside the riveted stainless-steel barrel shrugs off washdown, damp workshops and outdoor dust far better than painted-steel minis, and the CA pivot back cover connects directly to a clevis or bracket without adapters.

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 (Ø0mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 0 N | 0 N |
| 0.7 MPa | 0 N | 0 N |
| Max (@1.0 MPa) | 0 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA40X25SCA Is Used
Bench-top press stamping
A 25 mm stroke gives exactly enough travel for a marking or riveting die, and 628.3 N at 0.5 MPa crimps terminals or stamps date codes on electronics assemblies without a hydraulic unit.
Carton hold-down clamp
On a packaging machine end-of-line station, the CA pivot back cover swings the cylinder into a hold-down arm that pins flap-folders or trays during glue or tape application.
Fixture lid locking
Machining and test fixtures use the short throw to pull a hinged cover or locating pin into place; the stainless barrel and hard-chrome rod tolerate coolant splash around CNC work cells.
Is the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA40X25SCA the Right Cylinder?
Compare both neighbours before committing: one bore down, the MA32 delivers 402.2 N push at 0.5 MPa, while one bore up means moving to the MAC family, which adds adjustable air cushioning plus 50 and 63 mm bores if end-of-stroke deceleration must be tuned. Keep in mind that a plain MA drifts as soon as supply drops or the valve centres - nothing locks the rod - so add a pilot check valve or rod lock where a load must stay put. The 25 mm stroke suits short clamp-and-release motions; match the CA pivot back cover with an I or Y rod knuckle, or bolt on FA flange, LB foot or SDB pivot hardware if the machine frame needs a fixed mount. Every unit runs 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, and takes 1/8 inch ports on the covers with an M12x1.25 male rod thread.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA40X25SCA FAQ
At 0.5 MPa the 40 mm bore produces 628.3 N push and 527.8 N pull; raise supply to 0.7 MPa and output rises to 879.6 N push and 738.9 N pull. The theoretical ceiling at 1.0 MPa is 128.1 kgf. The cylinder is double acting over a 25 mm stroke with a 16 mm hard-chrome rod, 1/8 inch ports and M12x1.25 male rod thread, running 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Yes - every MA40X25SCA leaves the factory with the magnet already inside the piston, so CMSG, DMSG and EMSG reed or electronic switches clip onto the stainless barrel with no special-order piston. Note that the anti-impact pads at each stroke end are fixed, non-adjustable bumpers that only soften end impact; they are not an air cushion and they will not hold a load if air pressure is lost.
