Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 300mm 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 MF40X300SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty actuation within a compact footprint. Because the SUS304 stainless-steel barrel and riveted aluminium covers yield a shorter overall body than an ISO 6432 cylinder of the same bore and stroke, it slots neatly into space-constrained assemblies. The 1/4" port drives a 16 mm rod, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts without offering adjustable cushioning. The piston relies on a heterogeneous two-way seal that retains an oil film for extended operational life.
When sizing payloads, plan for approximately 377 N of actual work at 0.5 MPa, which equates to lifting about 32 kg vertically with a safe 2:1 margin. The built-in -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. Fitted with a CA rear pivot cover, this 300 mm stroke unit operates seamlessly between 30 and 800 mm/s across a -20 to +70 C temperature range.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300SCA Is Used
Stamping Press Ejection
Provides the 628.3 N of push force required to knock heavy stamped metal sheets out of a die, utilizing the 300 mm stroke to clear the press bed entirely.
Pallet Dispenser Pusher
Separates empty pallets on a conveyor line, where the CA pivot mount absorbs angular stress and the SUS304 barrel resists humid warehouse conditions.
Vertical Material Lift
Lifts approximately 32 kg of raw material between processing tiers, relying on the integrated magnet to trigger DMSG sensors at the upper and lower transition points.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300SCA the Right Cylinder?
If the 402.2 N push force of the 32 mm bore falls short of your payload requirements, stepping up to this 40 mm bore provides the necessary 628.3 N at 0.5 MPa; since 40 mm is the largest available MF dimension, any higher load demands an entirely different cylinder series. The -S magnet allows seamless integration of CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation. With a 300 mm stroke, be mindful of rod-bending side loads and ensure rigid guiding to prevent premature seal wear. Remember that the fixed TPU bumpers only decelerate the stroke end and will not brake or hold a load vertically; if air pressure drops, the piston drifts, so fit an external rod lock or pilot check valve for fail-safe suspension. The CA pivot back cover is ideal for clevis mounting to accommodate slight misalignment.
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 MF40X300SCA FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
The CA back cover provides a rear pivot point for clevis mounting, allowing the body to swing slightly to accommodate misalignment. At the stroke ends, fixed TPU bumper pads and a front-cover anti-impact pad absorb shock to decelerate the piston, but they do not provide adjustable air cushioning or position holding.
