Airtac MSF Single Acting Mini Cylinder MSF40X10CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X10CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MSF Single Acting Mini Cylinder MSF40X10CA
Delivering a robust 535.3 N of push force at 0.5 MPa (786.5 N at 0.7 MPa), this AirTAC MSF40X10CA is a JIS-standard round-body mini cylinder built for demanding short-stroke tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because it is a single-acting push type, air extends the 16 mm rod while an internal spring retracts it, meaning you only plumb a single 1/4" port. This compact body is notably shorter than a comparable ISO 6432 unit, saving valuable mounting length.
The quoted thrust is already net of the return spring, which dictates a strict 0.2 MPa operating floor to overcome the internal resistance. For practical sizing, a safe working load is roughly 321 N, or it can vertically lift about 27.3 kg with a 2:1 margin. This specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to the -S variant. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X10CA Is Used
Short-Stroke Clamping
Leverages the 535.3 N thrust to hold heavy workpieces firmly in machining fixtures, relying on the spring to release the part automatically when air is removed.
Package Ejector
Uses the 10 mm stroke to push heavy cartons off a transfer line, with the single-acting design cutting pneumatic plumbing complexity to one 1/4" line.
Pivot Gate Actuator
Pairs with the CA pivot cover to swing heavy diverter gates open, letting the internal spring pull the barrier shut as a fail-safe against air pressure loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X10CA the Right Cylinder?
When sizing this 40 mm bore unit, evaluate your thrust requirements bidirectionally. If 535.3 N at 0.5 MPa is excessive, the smaller MSF32 provides 323.3 N; as the largest available MSF bore, there is no larger standard option. This spring-return configuration is ideal for clamping, ejecting, or gating where the load must fail safely to the retracted position upon air loss. Ensure your supply meets the 0.2 MPa minimum to beat the spring. The integrated CA pivot back cover suits articulated rod-end loads, while standard LB, FA, SDB, and TC mounts cover fixed installations.
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 0.2 – 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 MSF Single Acting Mini Cylinder MSF40X10CA FAQ
This 40 mm bore cylinder generates 535.3 N of thrust at 0.5 MPa and 786.5 N at 0.7 MPa. Because these figures are net of the internal spring, you must supply at least 0.2 MPa to overcome the spring and extend the rod.
No, this specific SKU does not include a magnet and cannot support CMSG, DMSG, or EMSG switches. You must select the -S variant to enable magnetic sensing. Additionally, the fixed TPU bumpers handle end-stop damping, and the spring ensures the rod retracts on air loss rather than holding a mid-stroke load.
