About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200CA
The AirTAC MBLC20X200CA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering 157 N of push force and 132 N of pull force at 0.5 MPa, this 20 mm bore unit is built for fast, repetitive motion where a fixed rubber bumper would fail. The 200 mm stroke provides ample travel for extending actuators in tight assembly machinery.
This SKU features a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. It uses an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal. Note that this specific configuration lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing without modification.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200CA Is Used
PCB Router Z-Axis
Drives a small high-speed spindle up and down 200 mm for PCB depaneling, using the tunable cushion to stop the 157 N thrust smoothly without jarring the fragile board edges.
Pivot Arm Diverter
Swings a lightweight package diverter arm across a conveyor belt, utilizing the CA clevis to absorb the angular arc as the arm redirects small cartons.
Textile Bobbin Loader
Pushes an empty bobbin core into a winding spindle, relying on the adjustable air cushion to decelerate the 200 mm extension gently and prevent knocking the core out of alignment.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200CA the Right Cylinder?
When sizing this actuator, consider stepping down to a 20 mm bore if you need the absolute minimum footprint, but step up to the 25 mm bore (delivering 245 N push at 0.5 MPa) if your load mass requires greater thrust. Choose this MBLC version over the base MBL when your cycle speed exceeds what a fixed rubber bumper can absorb without causing end-cover impact or vibration. The adjustable needle decelerates the piston smoothly near each stroke end; however, it is a cushion, not a lock. A plain MBLC cylinder will not hold position if air is lost or the valve centers—the rod will drift. For replacement, match the 20 mm bore, 200 mm stroke, G1/8 port, PT thread, CA pivot back cover, and no magnet. Because the stroke is 200 mm, side-load tolerance is a concern; the CA clevis helps, but an external guide or a double-rod MBLCD is recommended for heavy lateral loads.
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 MBLC20X200CA FAQ
At 0.5 MPa, the 20 mm bore provides 157 N push and 132 N pull. At 0.7 MPa, it delivers 220 N push and 185 N pull. The theoretical maximum is 32 kgf at 1.0 MPa.
A screw-tunable needle valve at both stroke ends bleeds trapped air to decelerate the piston smoothly. You tune it to match the load and speed, cutting impact and noise on fast cycles. It is not a load lock or brake.
