About the Airtac B01-MA Special Cylinder B01-MA20X50SCA
This 20 mm bore, 50 mm stroke MA cylinder with CA pivot back cover runs double acting, so compressed air drives the rod out and pulls it back in. At the common 0.5 MPa working pressure it delivers 157 N on extend and 131.9 N on retract, rising to 219.8 N if you feed it 0.7 MPa. In practice that means it can lift a part of roughly 8 kg vertically once you keep a 2:1 force margin, or push through about 94 N of real resistive work at 0.5 MPa. Build quality is where this series earns its keep: the stainless-steel round barrel shrugs off the damp, washdown and light outdoor exposure that quickly ruin painted mini cylinders, while the hard-chrome plated 8 mm rod resists scoring over millions of cycles. Fixed anti-impact bumper pads soften the stroke ends (they decelerate, they are not adjustable air cushions - that is the MAC series), and a magnet is built into the piston as standard, so CMSG, DMSG or EMSG reed switches clip straight on for end-of-stroke signalling without any special-order piston.

Where the Airtac B01-MA Special Cylinder B01-MA20X50SCA Is Used
Bottle capping press
The 157 N extend force at 0.5 MPa seats snap caps or presses stoppers onto small bottles on a filling line, with the 50 mm stroke matching typical cap travel and the stainless barrel coping with daily washdown.
Conveyor stopper gate
Mounted on its CA pivot with an SDB bracket, the cylinder swings a stopper blade to pause cartons at a merge point on a packaging conveyor, lifting its own 8 kg-class gate assembly with margin.
Small-part ejection
On an electronics assembly bench, the 94 N of usable push force at 0.5 MPa knocks finished connectors or terminals out of a nest, while built-in magnet plus a CMSG switch confirms each stroke completed.
Is the Airtac B01-MA Special Cylinder B01-MA20X50SCA the Right Cylinder?
Check the force band first: if 157 N at 0.5 MPa is more than the job needs, the MA16 bore still gives 100.5 N push and 86.4 N pull at the same pressure; if the load grows past 219.8 N, step up to the MA25 bore which pushes 245.3 N. The 50 mm stroke sits well inside the 500 mm maximum for this bore, keeping the compact riveted body short. Remember the MA drifts when air is removed - for a load that must stay put on power loss, add a rod lock or pilot check valve downstream. The CA pivot cover pairs directly with SDB pivot brackets or I / Y rod knuckles for swinging motion, and FA flange or LB foot mounts are available if the machine needs a fixed position. The magnet is already on board, so position sensing with CMSG / DMSG / EMSG switches is just a snap-on accessory.
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 B01-MA Special Cylinder B01-MA20X50SCA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N; at 0.7 MPa those figures rise to 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa for this 20 mm bore. Operating pressure range is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and rod speed runs 30-800 mm/s.
The 20 mm bore takes 1/8 inch PT ports (G and NPT versions can be ordered by suffix), and the 8 mm hard-chrome rod carries an M8x1.25 external thread for your tooling. The CA pivot back cover lets the cylinder swing on an SDB bracket or knuckle, while FA flange and LB foot mounts cover fixed installations.
