About the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA25X400SCM
A 400 mm stroke on the 25 mm MA frame delivers a long-reach double acting cylinder that pushes 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa, with air driving the rod in both directions. Fixed anti-impact bumper pads ease the shock at each end of travel - a deceleration pad, not an adjustable cushion. The trailing CM code selects the round-end back cover, closing the body without a pivot lug so the cylinder sits flush in tight assemblies. In practical terms, plan on about 147 N of usable work from the 245.3 N rating at 0.5 MPa once a sensible margin is applied, which covers roughly 25 kg of vertical lift at full pressure or about 12 kg at a 2:1 safety factor. The riveted round body pairs a stainless-steel barrel with a 20 um hard-chrome plated rod, an honest advantage over painted minis in damp, dusty or lightly washed-down corners. A magnet is built in as standard, so CMSG, DMSG or EMSG switches mount straight onto the barrel.

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-MA25X400SCM Is Used
Reject gate lift
Raises a 10 to 12 kg reject paddle out of a bottling line conveyor path on the 245.3 N push at 0.5 MPa, with the CM round-end cover letting the body tuck under the guard rail.
Chip-enclosure slide door
Opens and closes a sliding access panel on a CNC machine guard, where the 400 mm stroke covers the full travel and the built-in magnet feeds position signal to the interlock via a CMSG switch.
Pallet stop and index
Stops and releases pallets on a roller conveyor leg, using about 147 N of working force at 0.5 MPa and LB foot mounting for a straight bolt-down frame.
Is the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA25X400SCM the Right Cylinder?
At 245.3 N push at 0.5 MPa, this 25 mm bore sits between the MA20 class (157.0 N) and the MA32 class (402.2 N); move down for light slides, up if friction or lifted mass climbs. Size the job against about 147 N of working force rather than the raw figure. As with any double acting MA, the piston is free to drift when air is removed, so a pilot check valve or rod lock is the answer where a 400 mm stroke has to stay parked. The long 10 mm rod deserves real guiding: side loads over 400 mm of travel chew seals and bend rods, so add a stop block or external guides for speeds up to 800 mm/s. Mount with FA flange or LB foot brackets, an SDB pivot, or I/Y knuckles, and note the port is 1/8 PT with an M10x1.25 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-MA25X400SCM FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum is 50.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), air filtered to 40 um, rod speed 30-800 mm/s and a working temperature of -20 to +70 C.
Yes - the magnet is built in as standard equipment on every MA-series cylinder, not an ordered option, so CMSG, DMSG or EMSG reed and hall-effect switches snap onto the stainless barrel anywhere along the 400 mm stroke for end-of-travel or mid-position signals without modifying the piston.
