About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300CA
The AirTAC MBLC25X300CA is a double-acting aluminum mini cylinder featuring a 25mm bore and a 300mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. This CA variant uses a pivot clevis back cover that swings on a pin, accommodating arcing loads rather than rigidly fixing the body. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.
A defining feature of this model is the screw-adjustable pneumatic air cushion at both stroke ends. Unlike a fixed rubber bumper, tuning the cushion needle decelerates the piston smoothly near the ends, cutting impact shock and vibration on faster moves. The cylinder relies on a riveted rolling-packed aluminum barrel for a compact, lightweight profile, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300CA Is Used
Pallet Transfer Pivot
Ideal for swinging a 300mm arm to index pallets between conveyors, using the CA clevis to absorb angular momentum while the air cushion softens the end-of-stroke stop at 245 N push.
Textile Loom Guide
Drives a 300mm yarn traversing mechanism in textile machinery, where the adjustable cushion prevents sudden jerks that would snap threads during high-frequency cycling.
Bin Tilting Mechanism
Pivots a small parts bin to dump contents into a hopper, with the clevis mount handling the arcing load and the cushion protecting the end covers from the falling mass.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300CA the Right Cylinder?
For sizing flexibility, stepping down to a 20mm bore drops the output to 157 N push at 0.5 MPa, whereas stepping up to a 32mm bore increases it to 402 N. Choose this MBLC over the base MBL when your cycle speeds or moved mass outclass a fixed rubber bumper. The CA pivot cover is essential here for managing angular motion. Because the stroke is 300mm, the small Ø10 mm rod has low side-load tolerance; use an external guide or a pivot bracket to prevent rod bending. Note that the cushion only decelerates near the ends—it is not a brake and will not hold position if air is lost. Replacement match: 25mm bore, 300mm stroke, G1/8 port, PT thread, CA back 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 MBLC25X300CA FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, it provides 343 N push. The maximum theoretical force is 50 kgf at 1.0 MPa.
This specific SKU lacks the -S code, so no CMSG, DMSG, or EMSG sensor can be fitted. The adjustable air cushion at both ends uses a needle valve to trap exhaust air, decelerating the piston smoothly near the ends to protect the end covers; it is a dampener, not a load lock.
