About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X80CA
The AirTAC MBLC20X80CA is a double-acting aluminum mini cylinder with a 20 mm bore and 80 mm stroke. It delivers 157 N of push force at 0.5 MPa. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both stroke ends to decelerate the piston, protecting the end covers on faster cycles.
The CA back cover provides a pivot clevis that swings on a pin to accommodate arcing or angular loads. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the Ø8 mm hard-chrome carbon-steel rod works with a heterogeneous two-way grease-retaining piston seal. Because this SKU lacks the -S magnet, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X80CA Is Used
PCB Component Insertion
Drives a delicate pick-and-place head inserting through-hole connectors into circuit boards, using the 80 mm stroke and tunable cushion to prevent jarring stops at 157 N push.
Bottle Diverter Arm
Actuates a pivot arm to deflect small pharmaceutical bottles between lanes, where the CA clevis accommodates the angular load and the air cushion softens the 80 mm move.
Test Socket Clamping
Applies 132 N of pull force to secure an IC chip against a spring-loaded test socket, relying on the compact 20 mm body to fit within dense tester fixtures.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X80CA the Right Cylinder?
This 20 mm bore yields 157 N push at 0.5 MPa. If your load is lighter, step down to the 12 mm bore (not in MBLC series, consider MSBL). If you need more force, step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. Choose this MBLC over a fixed-bumper MBL when cycle speeds exceed what a rubber bumper can absorb. The adjustable needle decelerates the load near the ends but does not lock the rod; if you need to hold position without live air, add an external rod lock. Replacement match: 20 mm bore, 80 mm stroke, G1/8 port, PT thread, CA pivot cover, no 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC20X80CA FAQ
At 0.5 MPa, the cylinder provides 157 N push and 132 N pull. At 0.7 MPa, it provides 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw needle at each end restricts exhaust flow near the stroke limits, trapping air to decelerate the piston smoothly. You tune the needle to match the load and speed, which cuts impact noise and vibration better than a fixed rubber bumper.
