About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SCA
The AirTAC MBL40X160SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force, making this 40 mm bore, 160 mm stroke unit well-suited for mid-range positioning tasks. The riveted rolling-packed barrel crimps the front and back covers directly to the aluminum tube, ensuring a lightweight, space-saving assembly that is permanently sealed rather than bolted together.
This specific SKU features a CA pivot back cover that allows the cylinder body to swing freely on a pin, accommodating arcing or angular loads during the 160 mm travel. Because it carries the -S suffix, a built-in magnet enables position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches. The carbon-steel piston rod is hardened with a 20 um chrome plating to resist wear and corrosion, while the internal heterogeneous two-way piston seal retains grease for a long, maintenance-free service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SCA Is Used
Textile Loom Tensioning
Swings on a pivot pin to maintain consistent fabric tension across a 160 mm travel arc, using its 628 N push force to guide material through weaving machinery without binding.
Package Divert Arm
Actuates a pivoting deflector gate on a packaging line, where the CA clevis mount absorbs lateral shock and the compact riveted body fits within tight transfer conveyor frames.
PCB Router Positioning
Drives a routing head across 160 mm to trace circuit board outlines, utilizing the -S magnet and a DMSG solid-state switch to confirm end-of-stroke position for the CNC controller.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SCA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa; conversely, moving up to the 50 mm bore provides 981 N for heavier payloads. This 160 mm stroke length pushes the limits of the Ø16 mm rod, meaning side-load tolerance is low. For an unsupported span of this length, you should use an external guide rail to prevent rod-bearing bending, rely on the CA pivot back cover to absorb angular misalignment, or switch to the MBLD double-rod type for rigid anti-rotation. Remember that the fixed rubber bumper only softens end-of-stroke impact; it does not hold the load. If air pressure drops, the rod will drift, so fit an external pilot-operated check valve if position holding is critical. For exact replacement matching, confirm: 40 mm bore, 160 mm stroke, G1/4 port, PT thread, CA pivot back cover, and -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. Increasing the pressure to 0.7 MPa yields 880 N of push force. The maximum theoretical force is 128 kgf at 1.0 MPa, which is the upper operating pressure limit for this model.
No, the base MBL40X160SCA uses a fixed rubber bumper to soften the impact at the end of the stroke, not an adjustable cushion screw. If your application requires precise end-of-stroke deceleration for heavier moving loads, you should upgrade to the MBLC variant which features adjustable air cushioning.
