About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500CA
The AirTAC MBLC25X500CA is a double-acting, single-rod aluminum mini cylinder featuring a 25 mm bore and a 500 mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke extremes, cutting impact shock and vibration on long, fast moves. This is a tunable deceleration feature, not a load lock.
Configured with a CA pivot clevis back cover, this cylinder swings on a pin to accommodate arcing angular loads. It uses a G1/8 port and a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating. The riveted rolling-packed aluminum barrel keeps the body compact. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500CA Is Used
Textile Loom Tensioning
Drives a 500 mm stroke to position yarn guide arms on a weaving loom, using the CA clevis to absorb angular arc while the air cushion prevents end-cap knock at high cycling frequencies.
Packaging Sorter Diverter
Pushes light cartons across a belt at 245 N push force, where the adjustable cushion smoothly stops the 500 mm extension to protect the mechanical pivot from sudden impact.
Vertical Parts Elevator
Lifts tote bins 500 mm in a compact storage retrieval unit; the pneumatic cushion decelerates the load at the top end to prevent bounce, while the CA pivot handles slight rod misalignment.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500CA the Right Cylinder?
At 0.5 MPa, this 25 mm bore delivers 245 N push and 206 N pull. If you need less force, the 20 mm bore offers 157 N push / 132 N pull; if you need more, the 32 mm bore provides 402 N push / 346 N pull. Choose this MBLC over the base MBL when operating at high speeds or high cycle frequencies, as the fixed rubber bumper on the MBL cannot absorb the kinetic energy of a 500 mm move as effectively as a tuned air cushion. The cushion needle only decelerates the piston near the ends; it does not hold position if air is lost or the valve centers—use an external rod lock for pilot-operated check for holding.
For replacement, match the 25 mm bore, 500 mm stroke, G1/8 port, M10x1.25 rod thread, PT port thread form, and CA pivot back cover. Because the stroke is 500 mm, the small Ø10 mm rod has low side-load tolerance. You must manage rod bending with an external guide, the CA/SDB pivot, or the MBLD double-rod type to prevent premature seal wear.
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 MBLC25X500CA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, it provides 343 N of push force. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. This specific SKU does not have the -S suffix, meaning it lacks a built-in magnet. To use AirTAC CMSG, DMSG, or EMSG sensor switches, you must select the MBLC25X500S or MBLC25X500CA-S variant.
