Airtac MF32-40 Stainless Steel Mini Cylinder MF32X170SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X170SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 170mm 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 MF32X170SCA
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a CA pivot back cover for articulated rear mounting. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because the MF body is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 170 mm stroke, it saves valuable mounting length in tight machinery.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Equipped with a 1/4 inch port and an M10x1.25 male rod thread, it operates at 30-800 mm/s. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X170SCA Is Used
Package Diverting Arm
Swings a sorting gate on a packaging line using the CA pivot mount, utilising the 402.2 N push force to deflect medium-weight cartons reliably.
Vertical Parts Lift
Raises lightweight industrial totes weighing up to 20.5 kg in a compact assembly cell, taking advantage of the shorter JIS body length to fit tight vertical spaces.
Pneumatic Clamping Fixture
Secures aluminium housings for machining operations, where the oil-retaining two-way seal ensures consistent actuation over high cycle counts.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X170SCA the Right Cylinder?
If 245.3 N from the MF25 is insufficient for your fixture, this 32 mm bore steps up the power without a massive footprint; should you need even more thrust, the MF40 provides 628.3 N at 0.5 MPa. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG electronic or reed switches for position sensing. The included CA pivot back cover suits angular movement requirements.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If air pressure drops or the valve is centred, the piston will drift and drop the load. To maintain vertical position securely, install an external pilot-operated check valve or a dedicated rod lock.
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 MF32X170SCA FAQ
This 32 mm bore cylinder features a 1/4 inch port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
The CA back cover provides a pivot pin for angular rear mounting. At stroke endpoints, fixed TPU bumper pads and a front-cover anti-impact pad decelerate the piston to reduce shock. Note that these bumpers do not lock the rod; an external rod lock is required to hold a load safely.
