About the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA20X250SCM
For a compact 20 mm bore, MA20X250SCM delivers 157 N of push and 131.9 N of pull at 0.5 MPa (22-145 psi), enough muscle to index small trays or eject light parts across a 250 mm travel. The cylinder is double acting with fixed anti-impact bumper pads at both stroke ends, and the high-precision stainless barrel is riveted straight onto the aluminium-alloy covers, so the round body stays tight even on vibrating benchtop machines. In day-to-day sizing, plan real work at roughly 94 N instead of the full 157 N rating and the cylinder runs with a comfortable margin; on a vertical lift the rod will handle about 8 kg with a 2:1 safety factor. The carbon-steel rod is hard-chrome plated to 20 um, which lets this mini shrug off washdown splashes that rust painted-steel bodies, and the magnet is built in as standard so CMSG, DMSG or EMSG switches drop straight on without a special piston.

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-MA20X250SCM Is Used
Vial tray lift on a lab carousel
A 250 mm raise-and-lower station that hoists about 8 kg of loaded vial trays in steps, using the 157 N push force at 0.5 MPa with a 2:1 vertical margin and the built-in magnet for mid-stroke sensing.
Reject gate on a bottling line
A swing or push-off gate beside the conveyor that tips underweight bottles off the belt, where the stainless barrel and chrome rod shrug off daily washdown splashes that corrode painted minis.
Carton indexing on a benchtop sealer
A feed pusher that advances small folding cartons 250 mm into the sealing nest at up to 800 mm/s, with the fixed bumper pads softening both stroke ends cycle after cycle.
Is the Airtac B52-MA Copper-Free Stainless Steel Mini Cylinder B52-MA20X250SCM the Right Cylinder?
Weigh the neighbours first: the 16 mm bore manages only 100.5 N at 0.5 MPa, while stepping up to 25 mm buys 245.3 N - go larger if your friction or part weight sits above the roughly 94 N this bore should realistically carry. With 250 mm of travel on an 8 mm rod, keep side loads off the rod and guide the tooling externally, because rod bending grows quickly over an unprotected overhang this long. This SKU carries the PT pipe thread as standard on its 1/8" ports, with G and NPT versions orderable if your manifold follows another plumbing standard. The CM round-end back cover on this model is a fixed rear mount; add FA flange, LB foot or SDB pivot brackets where the frame demands them. Remember that a plain MA does not lock itself - the piston drifts the moment air is dropped, so fit a rod lock or pilot check valve wherever a position or load must stay put.
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-MA20X250SCM FAQ
At 0.5 MPa the 20 mm bore pushes 157 N and pulls 131.9 N double acting; at 0.7 MPa push rises to 219.8 N, and the theoretical maximum is 32 kgf at 1.0 MPa. The cylinder runs on 0.15-1.0 MPa (22-145 psi) with 30-800 mm/s speed, an 8 mm rod cut to M8x1.25, and 1/8" PT ports.
Yes - every MA piston is supplied with a built-in magnet, so CMSG, DMSG or EMSG reed sensors mount on the barrel as a straight fit rather than a special order. The barrel itself is high-precision stainless steel riveted to the aluminium covers, the rod is hard-chrome plated to 20 um, and the fixed anti-impact bumper pads simply decelerate the stroke end - they are not an adjustable cushion, which is what the MAC family adds.
