Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 550mm 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 MF32X550U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles demanding actuation with a 550 mm stroke. Because 550 mm exceeds the 500 mm standard limit, this specific length is manufactured as a made-to-order item. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for extended mechanical life.
Featuring a 1/4" port and an M10x1.25 male rod thread, the unit relies on fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impacts. For a 0.5 MPa working pressure, plan for roughly 241 N of actual work output, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The U flat-end back cover provides a flush rear mounting face for direct fixture attachment.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550U Is Used
Carton Push-Off Diverter
Uses the 402.2 N push force at 0.5 MPa to deflect heavy packaged goods across a packaging conveyor line over a 550 mm reach.
Vertical Parts Elevator
Lifts components weighing up to 20.5 kg between machinery tiers, taking advantage of the U flat-end cover for stable base mounting.
Long-Reach Gripper Actuation
Extends an end-of-arm tooling jaw by 550 mm to extract molded parts from deep injection molding machine cavities.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550U the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches; you must select an -S variant if electronic sensing is required. You can mount the body using LB foot, FA flange, SDB pivot, or TC trunnion hardware.
At a 550 mm length, the rod is susceptible to bending under severe side loads, so ensure the load moves along a guided track. Note that venting the air causes the piston to drift, as the TPU pads only decelerate the stroke end rather than locking the rod; a pilot-operated check valve is required to suspend a vertical load safely.
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 MF32X550U FAQ
This 32 mm bore cylinder features a 1/4" 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.
This specific SKU lacks a magnet, so CMSG, DMSG, or EMSG switches cannot be used. For the same bore and stroke, the JIS-standard MF body is shorter than an ISO 6432 cylinder, saving mounting length. It uses fixed TPU bumper pads rather than an adjustable air cushion.
