Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCM
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 25mm 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-MAC40X25SCM
A CM round-end rear cover leaves this 40 mm MAC with a smooth domed back - handy where a rear plate, spring or guide pin must sit flush behind the cylinder. Air works the piston in both directions, and twin needle cushions, adjustable from fully open, absorb the 628 N (628.3 N exact) delivered at 0.5 MPa so cycling does not batter the covers.
Build quality is where this mini earns its keep: a high-precision stainless tube with aluminium covers rolled on, and a 16 mm carbon-steel rod plated 20 um hard chrome. Practical planning figure: about 377 N of usable push at 0.5 MPa, which is close to 32 kg lifted vertically once a 2:1 factor is applied.

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 B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCM Is Used
Connector press-fit head
Pressing board connectors needs steady 400-600 N; the 40 mm bore delivers 628 N at 0.5 MPa and the cushions ease the ram off at bottom of stroke.
Vial stopper seating at a pharma filler
The chrome-plated rod and stainless barrel tolerate isolator humidity, and the built-in magnet with an EMSG switch verifies each stopper seat.
Load backrest latch on an AGV cart
The domed CM rear clears the guide roller track while 628 N of push holds the latch shut over warehouse thresholds.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCM the Right Cylinder?
Neighbouring sizes frame the choice: bore 32 manages 402 N push at 0.5 MPa and bore 50 manages 981 N, so 40 mm suits medium loads that 32 mm would stall on. This actuator holds nothing when air drops - expect the rod to coast under gravity or spring-back from the load - so fit a rod lock or pilot check valve for parked positions. The CM end takes custom rear fittings, while FA flange, LB foot and SDB pivot brackets cover standard frames and I or Y knuckles pick up the tooling. Operating window is 0.15-1.0 MPa (22-145 psi); the magnet is fitted as standard for CMSG / DMSG / EMSG switches.
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-MAC40X25SCM FAQ
Push at 0.5 MPa is 628 N (628.3 N exact), pull at 0.5 MPa is 528 N, push at 0.7 MPa is 880 N (879.6 N), and theoretical maximum force is 128 kgf at 1.0 MPa. Rod diameter is 16 mm with an M12x1.25 male thread.
Back both needle screws fully open before first air, then close them gradually until the end-of-stroke sound softens. The variable air cushion works identically on extend and retract across the 30-800 mm/s speed range.
