About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250CA
The AirTAC MBLC20X250CA is a double-acting aluminum mini cylinder with a 20 mm bore and 250 mm stroke, delivering 157 N of push force and 132 N of pull force at 0.5 MPa. It features a CA pivot clevis back cover that swings on a pin, making it ideal for arcing loads where a rigid flat-end mount would induce side-load binding. This SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensing without modification.
Unlike the base MBL series, which relies on a fixed rubber bumper, this MBLC model uses a screw-adjustable pneumatic air cushion at both ends. This allows you to tune the end-of-stroke deceleration to match your load and speed, effectively reducing impact shock, vibration, and noise on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the body compact and light, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over the cylinder's service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250CA Is Used
Textile Loom Guide Arm
Drives an arcing guide arm on a textile weaving loom, using the CA pivot to accommodate the angular motion while the 250 mm stroke shifts the warp beam with 157 N of push force at 0.5 MPa.
Packaging Diverter Gate
Actuates a lightweight cardboard diverter gate on a packaging conveyor, where the adjustable air cushion ensures the 250 mm stroke extends smoothly without slamming the end cover at high cycle speeds.
PCB Component Shuttle
Moves a small component shuttle in a PCB assembly machine, utilizing the compact 20 mm riveted aluminum body to fit within tight machine guarding while providing 132 N of retraction force.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250CA the Right Cylinder?
At 0.5 MPa, this 20 mm bore yields 157 N push and 132 N pull. If your application requires less force, there is no smaller standard MBL size, so you must reduce pressure or look outside the series. If you need more power, stepping up to the 25 mm bore provides 245 N push and 206 N pull. Choose this MBLC over the base MBL when your 250 mm stroke operates at higher cycle rates or speeds where a fixed rubber bumper would wear out too quickly or cause damaging end-cover impact.
Because this model lacks the -S suffix, it has no internal magnet and cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. The port thread is PT (tapered), and the rod end features an M8x1.25 thread on an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating. For a 250 mm stroke on an 8 mm rod, side-load tolerance is low; the CA pivot clevis on this unit helps accommodate angular misalignment, but an external guide rail or a double-rod MBLD type is recommended if the load is prone to twisting or 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 MBLC20X250CA FAQ
This 20 mm bore cylinder provides 157 N push and 132 N pull at 0.5 MPa, and 220 N push and 185 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, runs at speeds of 30-800 mm/s, and uses a G1/8 port with an M8x1.25 rod thread.
This specific MBLC20X250CA SKU does not have a built-in magnet, so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends is tuned via a screw needle; it restricts exhaust air flow near the stroke ends to decelerate the piston smoothly, reducing impact and noise on fast moves without acting as a load lock or brake.
