About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15SCA
The AirTAC MBLC40X15SCA is a compact double-acting aluminum mini cylinder engineered for short 15 mm strokes, delivering a robust 628 N push force at 0.5 MPa. Unlike the base MBL, this variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle valves to smoothly decelerate the piston near each stroke limit, eliminating harsh end-cover impacts on high-frequency cycles.
This SKU includes a CA pivot clevis back cover that swings on a pin to accommodate arcing loads, along with a built-in magnet (-S) for position detection. The riveted rolling-packed aluminum barrel keeps the body light and tight for machine integration, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15SCA Is Used
Short-Stroke Stamping
Ideal for driving a 15 mm stamping or embossing head in consumer electronics assembly, using its 628 N thrust to mark casings without overtravel.
Pivot Gate Diversion
The CA clevis allows the cylinder to swing a diverter gate on a packaging line, rapidly routing cartons with precise position feedback from the -S magnet.
PCB Edge Clamping
Provides rigid 15 mm clamping of printed circuit boards during wave soldering, where the adjustable air cushion ensures soft contact to prevent board fracture.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15SCA the Right Cylinder?
Select this 40 mm bore when you need 628 N of push force at 0.5 MPa for a very compact 15 mm stroke. If your payload is lighter, step down to the 32 mm bore providing 402 N; if you need more power, step up to the 50 mm bore yielding 981 N. Choose this MBLC cushioned version over the fixed rubber bumper of the standard MBL when cycling rapidly, as the tunable cushion protects the end covers. The CA clevis is ideal for angular movements, but note that a plain cylinder does not hold position if air pressure drops—the cushion only decelerates, it does not lock the rod.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15SCA FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
The screw-tunable air cushion at both ends traps exhaust air to decelerate the piston smoothly near the stroke ends, which is superior to a fixed rubber bumper for high-speed moves. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to detect rod position.
