About the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA20X40SU
With a 20 mm bore pushing 157 N at 0.5 MPa, the MA20X40SU covers light clamping and positioning work in a compact round body. It is double acting with fixed anti-impact bumper pads at each stroke end, and the SU suffix means the flat-end (U) back cover is fitted instead of the pivot or round-end style. AirTAC rolls the aluminium covers onto a high-precision stainless barrel, so the body shrugs off damp shop air and occasional washdown far better than painted-steel minis. Every unit is supplied with a built-in magnet as standard, so a CMSG, DMSG or EMSG switch drops straight on for end-of-stroke signalling with no special-order piston. Budget real work around 94 N at 0.5 MPa (about 60 percent of the push rating); vertically that equals roughly 8 kg of lift with a 2:1 margin. Speed range is 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).

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-MA20X40SU Is Used
Bottle-guide actuation on a filling line
A 40 mm stroke is enough to swing or push bottle guide rails in and out for changeovers, and the stainless barrel copes with the wet, rinsed-down environment around rinse-fill stations.
Finished-part kick-off from a small assembly fixture
With 157 N of push at 0.5 MPa, the MA20X40SU sweeps machined or moulded parts off a nest into a chute; the built-in magnet drives a CMSG switch to confirm the retracted position before the next cycle.
Lifting latch on a light machine guard or hopper gate
Rated near 16 kgf at 0.5 MPa, the bore lifts a sub-8 kg gate lid with margin, while the fixed bumper pads soften the open and closed stops so the frame is not hammered every cycle.
Is the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA20X40SU the Right Cylinder?
Size against the neighbours: stepping down, the MA16X40 manages about 100.5 N push at 0.5 MPa, while stepping up, the MA25X40 reaches 245.3 N. Pick by real load rather than bore habit. Bear in mind this cylinder will not hold position when air is lost or the valve centres - the rod drifts freely, so fit a pilot check valve or rod lock wherever a load must stay put. The flat-end U back cover suits fixed screw fixing; CA pivot and CM round-end covers, plus FA flange, LB foot or SDB pivot brackets, cover the moving-mount cases. Ports are 1/8" and the 8 mm rod takes an M8x1.25 male 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-MA20X40SU FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. Raise supply to 0.7 MPa and those figures climb to 219.8 N push and 184.7 N pull. The theoretical ceiling for the 20 mm bore is 32 kgf at 1.0 MPa. Working numbers around 94 N at 0.5 MPa are a sensible planning figure for real mechanisms.
The high-precision stainless barrel paired with a hard-chrome plated 20 um carbon-steel rod resists mild corrosion and washdown spray, and the riveted round body keeps the install footprint tight. Fixed bumper pads soften stroke-end impact, though they are not an adjustable air cushion - that belongs to the MAC series. The position magnet is built in as standard, so CMSG, DMSG and EMSG switches mount with no extra order.
