Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder is built around a SUS304 stainless steel barrel with riveted aluminium covers. The JIS-standard round-body architecture is specifically designed to be shorter than an ISO 6432 cylinder for the same 160 mm stroke, saving valuable mounting length in tight machinery. It features a CM round-end rear cover and a built-in piston magnet for position sensing.
The piston relies on a heterogeneous two-way seal that retains an oil film for extended lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. The 1/4" port and M14x1.5 male rod thread handle the high airflow needed to move the 16 mm rod at 30-800 mm/s.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM Is Used
Carton Diverting Gate
Uses the 628.3 N push force at 0.5 MPa to pivot heavy cardboard diverters on packaging lines without stalling under friction.
Pneumatic Press Platen
Presses small bearings or pins into housings, relying on the fixed TPU bumper pads to absorb the impact at the end of the 160 mm stroke.
Pallet Stopper Arm
Deploys a robust stopping barrier in conveyor accumulation zones, where the CM round-end cover pivots smoothly to absorb pallet impacts.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM the Right Cylinder?
When sizing this 40 mm bore, compare it directly against the smaller MF32, which provides 402.2 N of push at 0.5 MPa. Since 40 mm is the largest available bore in the MF family, moving beyond 628.3 N requires stepping up to a different cylinder series entirely. The integrated -S magnet allows seamless mounting of CMSG, DMSG, or EMSG electronic switches along the stainless body.
Because this is a double-acting cylinder with fixed TPU bumpers, it will drift if air pressure drops or the valve is centred, as the bumpers only decelerate the stroke end rather than locking the load. For vertical or suspended loads that must remain held during air loss, install an external pilot-operated check valve or a dedicated rod lock. The 160 mm stroke is well within the 500 mm standard limit, though you should still support the rod to prevent side-loading and bending on longer extensions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCM FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore cylinder uses a 1/4" air port and an M14x1.5 male piston rod thread.
It does not conform to ISO 6432, though its JIS-standard round body is deliberately shorter than an ISO 6432 cylinder, saving mounting length. The included -S magnet supports CMSG, DMSG, and EMSG switches, and you can mount it using LB foot, FA flange, SDB pivot, or TC trunnion brackets.
