About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X80CA
The AirTAC MBLC25X80CA is a double-acting aluminum mini cylinder with a 25 mm bore and 80 mm stroke, delivering 245 N push and 206 N pull at 0.5 MPa. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke extremes, cutting impact noise on faster cycles. An 80 mm travel suits compact ejector strokes or small part positioning where a fixed bumper would wear prematurely.
This SKU features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces, while the Ø10 carbon-steel rod with 20 µm hard-chrome plating resists corrosion. Note that because this configuration lacks the -S suffix, it has no internal magnet and cannot host a CMSG, DMSG or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X80CA Is Used
Angular Part Ejection
The CA pivot mount absorbs arcing motion on a packaging machine's rotary dial, using the 245 N push force to kick empty blister packs into a sorting chute.
Pallet Diverter Arm
Tunable air cushioning silently decelerates the 80 mm stroke as the cylinder pushes lightweight aluminum pallets onto a secondary conveyor belt line.
PCB Test Nest
Provides 206 N pull force to retract a spring-loaded test probe plate in an electronics assembly fixture, with the cushion preventing harsh snap-back.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X80CA the Right Cylinder?
Select this 25 mm bore when you need 245 N of push force at 0.5 MPa with dynamic end-control. If your application is lighter, stepping down to the 20 mm bore yields 157 N push, whereas heavier payloads require stepping up to the 32 mm bore for 402 N. The PT tapered port thread matches the standard G1/8 fitting size for this bore class.
Choose the MBLC over the fixed-bumper MBL when cycling speeds or attached masses demand tunable end-of-stroke deceleration. Remember that the adjustable cushion only slows the piston near the ends; it is not a brake, so the rod will drift if air is lost or the valve centers. For external positioning without live air, install a separate rod lock.
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 MBLC25X80CA FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it provides 343 N push and 289 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. It uses a G1/8 port with PT tapered threading, a Ø10 mm rod, and an M10x1.25 rod-end thread.
The screw-adjustable air cushion at both ends lets you tune end-of-stroke deceleration to protect end covers on fast or heavy moves, unlike a fixed rubber bumper. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG or EMSG sensor switches for position detection.
