About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SCA
The AirTAC MBLC20X75SCA is a compact double-acting aluminum mini cylinder engineered for tight spaces. It delivers 157 N of push force at 0.5 MPa and features a 75 mm stroke. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 um hard-chrome plating on the carbon-steel rod protects against friction wear.
This model uses a screw-adjustable pneumatic air cushion at both stroke ends to decelerate the piston smoothly, cutting end-cover impact and vibration on faster cycles. The built-in magnet (-S) enables position sensing with CMSG, DMSG, or EMSG switches. A CA pivot/clevis back cover allows the body to swing on a pin, accommodating arcing loads that would bind a rigid mount.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SCA Is Used
Electronic Pick-and-Place
Drives a small suction cup arm in a PCB assembly station. The 75 mm stroke and 157 N force move lightweight electronics, while the cushion ensures gentle landings to protect fragile components.
Packaging Diverter
Sorts small cardboard cartons on a packaging line. The CA pivot allows the cylinder to swing the diverter arm accurately, absorbing the impact of high-frequency routing moves.
Textile Yarn Guide
Shifts a yarn guide across a weaving machine. The compact 20 mm barrel fits tight loom spaces, and the cushioning prevents end-of-stroke vibrations from disturbing thread tension.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SCA the Right Cylinder?
At 0.5 MPa, this 20 mm bore yields 157 N push and 132 N pull. If your application requires less force, step down to the 20 mm bore's smaller 16 mm counterpart (confirm from datasheet), or step up to the 25 mm bore for 245 N push. Choose this MBLC cushioned version over the base MBL when your cycle speeds or load mass exceed what a fixed rubber bumper can absorb. The CA pivot mount is ideal for arcing trajectories, but for straight-line pushes over 300 mm, consider an external guide or the MBLD double-rod type to prevent rod bending.
For replacements, match the 20 mm bore, 75 mm stroke, G1/8 port, M8x1.25 rod thread, PT port thread, CA pivot back cover, and built-in magnet. Note that a plain MBLC does not hold position when air is lost; the cushion only decelerates near the ends and is not a brake.
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 MBLC20X75SCA FAQ
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, push is 220 N and pull is 185 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly near the stroke limits. You tune it to match your load and speed, which reduces end-cover impact and noise. It is not a load lock or brake.
