About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30CA
The AirTAC MBLC20X30CA is a compact double-acting aluminum mini cylinder engineered for tight assembly spaces. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa from a 20 mm bore. The 30 mm stroke provides short, rapid linear motion, while the CA back cover features a pivot clevis that swings on a pin to accommodate arcing or angular loads without binding.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant utilizes a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to decelerate the 8 mm carbon-steel rod smoothly near the end limits, cutting impact shock and vibration on faster cycles. The riveted rolling-packed aluminum barrel keeps the body light, and the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication. Note that this specific SKU lacks a built-in magnet, so it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30CA Is Used
Electronic Component Testing
Drives a 30 mm probe stroke to test PCB contacts, using the adjustable cushion to decelerate the 8 mm rod gently and prevent micro-fractures on delicate circuit boards.
Packaging Diverter Arm
Pivots a small guide arm via the CA clevis to sort light parcels on a conveyor, absorbing the angular load while cushioning the rapid 30 mm flip.
Pick-and-Place Ejector
Ejects small silicon wafers from a test socket with 157 N of push force, relying on the riveted aluminum barrel for compact mounting in dense machinery.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30CA the Right Cylinder?
For applications requiring less force, step down to the 20 mm bore's smaller alternatives if available, but to increase output, step up to the 25 mm bore which provides 245 N push at 0.5 MPa. Choose this MBLC over the base MBL when your cycle speeds are high enough that a fixed bumper would cause premature end-cover wear. The adjustable cushion decelerates the load near the ends but does not lock the rod; if you need position holding without live air, install an external rod lock. Replacement match: 20 mm bore, 30 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 MBLC20X30CA FAQ
At 0.5 MPa, it provides 157 N push and 132 N pull. At 0.7 MPa, it yields 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw needle at both ends lets you tune the pneumatic cushioning to match your load and speed. It decelerates the piston smoothly near the stroke limits to reduce impact and noise, but it is not a load lock or brake.
