Airtac B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 20mm stroke, PT/G air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM
Short 20 mm of travel in a 16 mm round stainless barrel defines the MAC16X20SCM. Air drives the rod both ways - it is fully double acting - and a variable cushion at each end tames the stop, while the factory-fitted magnet readies the cylinder for CMSG, DMSG or EMSG switches. Output at 0.5 MPa is 100.5 N forward and 86.4 N back, from a compact body running 0.15-1.0 MPa (22-145 psi).
A practical reading of that rating: count on around 60 N for real work at 0.5 MPa, which vertically corresponds to lifting roughly 5 kg with a 2:1 margin - enough for a light sorting finger or a small part nudge. The riveted stainless tube and hard-chrome plated 6 mm rod laugh off splash and mild washdown, a genuine edge over painted mini bodies in damp food or outdoor spots.

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 B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM Is Used
Part-present gate on an assembly dial
A 20 mm push confirms a component is seated before the press cycle starts; the cushion stops the 6 mm rod sharply without bounce, and a DMSG switch signals the confirmed position.
Carton flag kicker on a case sealer
Flicks a folding flag on small cartons as they pass; 100.5 N at 0.5 MPa easily swings the lightweight flag and the stainless body copes with glue-residue wipe-downs.
Needle valve indexer on a dosing skid
Toggles a small dosing valve between two positions; the CM round-end cover mounts flush to the skid plate and the short stroke keeps cycle time tight.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM the Right Cylinder?
Twenty millimetres is ideal for confirm-and-nudge motions, not long reaches. If the job needs more force than the 100.5 N this bore offers at 0.5 MPa, a 20 mm MAC gives 157.0 N and a 25 mm version 245.3 N without changing panel space much. Note the cylinder will drift if supply air drops - position is not held - so add a pilot check valve or rod lock where that matters. The CM round-end cover suits fixed or pivot take-offs, FA flange, LB foot and SDB brackets extend the mounting choice, cycling speed covers 30-800 mm/s, and M5x0.8 ports on PT thread are standard.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-MAC Series Special Purpose Cylinder B01-MAC16X20SCM FAQ
Expect 100.5 N pushing and 86.4 N pulling at 0.5 MPa, climbing to 140.7 N and 120.9 N at 0.7 MPa. The theoretical maximum is 20.5 kgf at 1.0 MPa. The 6 mm rod carries an M6x1.0 thread, ports are M5x0.8, the stroke is 20 mm within a 500 mm standard capability, and speed ranges 30-800 mm/s.
Even over 20 mm the cushion bleeds air gradually at each end, so you can raise speed or add a heavier fixture without metal-to-metal hammer on the covers. Release the cushion screws fully before first run, then adjust them gradually until the stop is smooth.
