About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150CA
The AirTAC MBLC25X150CA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 245 N of push force at 0.5 MPa over a 150 mm stroke, it is tailored for mechanisms requiring smooth deceleration of heavier or faster moving loads. The riveted rolling-packed aluminum barrel keeps the body light and spatially efficient, while the 20 µm hard-chrome plated carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.
This specific configuration includes a CA pivot clevis back cover, allowing the cylinder to swing on a pin and safely absorb angular misalignment during arcing motion. Because this SKU lacks the -S magnet suffix, it cannot support a CMSG, DMSG or EMSG position sensor. The adjustable air cushion is strictly an end-of-stroke deceleration feature; it reduces impact stress on the end covers but does not function as a mechanical lock to hold the load when air pressure is removed.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150CA Is Used
Pick-and-Place Arms
Drives the horizontal swing arm on a PCB assembly pick-and-place head, using the CA pivot to accommodate the arcing motion while the air cushion decelerates the 150 mm stroke smoothly.
Sorting Diverter
Actuates a pneumatic diverter gate on a small-parts packaging conveyor, where the adjustable cushion slows the 245 N thrust impact to prevent jarring the aluminum gate mechanism.
Carton Flap Folder
Folds secondary cardboard flaps on a compact carton erecting machine, relying on the tunable end-cushioning to cycle rapidly without hammering the end covers.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150CA the Right Cylinder?
Select this 25 mm bore when your application demands 245 N of push force at 0.5 MPa alongside a pivoting CA mount and 150 mm of travel. If you need less force, stepping down to the 20 mm bore yields 157 N of push; if your load requires more thrust, stepping up to the 32 mm bore provides 402 N. Choose this MBLC variant over the fixed rubber bumper of the base MBL when your cycle speeds exceed what a standard bumper can absorb without causing excessive noise or vibration. To match this exact replacement, verify the 150 mm stroke, G1/8 port, PT thread form, CA pivot back cover, and the absence of a magnet. Because the 150 mm stroke is relatively long for a 10 mm rod, use an external guide or ensure the CA clevis absorbs any rod-side loading to prevent bending.
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 MBLC25X150CA FAQ
This 25 mm bore cylinder uses a G1/8 port and a Ø10 mm rod with an M10x1.25 thread. At 0.5 MPa it provides 245 N of push force and 206 N of pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it strikes the end cover. You tune the needle to match your specific load and speed, which cuts impact noise and vibration. It is strictly a deceleration device, not a load lock or brake.
