About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X500SCA
The AirTAC MBLC20X500SCA is a compact double-acting aluminum mini cylinder engineered for a 500 mm stroke. It produces 157 N of push force and 132 N of pull force at 0.5 MPa. Equipped with a built-in magnet (-S), it supports CMSG reed and DMSG or EMSG solid-state sensor switches for precise end-of-stroke detection. The CA pivot back cover allows the body to swing on a pin, accommodating arcing or angular movements without binding.
Unlike the base MBL series with its fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle decelerates the piston smoothly near the stroke extremes, absorbing kinetic energy to protect the end covers on faster moves. The riveted rolling-packed aluminum barrel keeps the profile small for tight spaces, while the Ø8 mm hard-chrome carbon-steel rod resists corrosion. Note that the cushion only decelerates; it is not a load lock or brake.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X500SCA Is Used
Textile Loom Yarn Guide
Drives a yarn traversing guide across a 500 mm span at high frequency. The CA pivot absorbs angular rod stress while the adjustable air cushion prevents sudden end-stop snapping on fast reversals.
PCB Sorting Diverter
Pushes populated PCB panels into testing lanes. The CMSG reed switch confirms full extension, while the compact 20 mm barrel fits within the tight clearance of the conveyor frame.
Pharmaceutical Vial Reject
Sweeps defective vials off a high-speed packing line. The tunable cushion decelerates the 500 mm stroke smoothly, ensuring glass vials are not jolted off the pusher arm.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X500SCA 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 would rely on pressure regulation. If you need more power, stepping up to the 25 mm bore provides 245 N push and 206 N pull. Choose this MBLC version over the fixed-bumper MBL when your cycle speeds are higher or the moved mass demands tunable end-of-stroke deceleration to cut impact noise.
At 500 mm of stroke, the thin Ø8 mm rod has high susceptibility to side-loading and rod bending. To prevent premature seal wear or buckling, you must use an external linear guide, a CA/SDB pivot mount, or switch to an MBLD double-rod cylinder. This specific SKU includes a CA pivot back cover and uses a PT port thread. A plain MBLC does not hold position if air is lost; for drop prevention, add an external rod lock or pilot-operated check valve.
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 MBLC20X500SCA FAQ
At 0.5 MPa, it delivers 157 N push and 132 N pull. At 0.7 MPa, it delivers 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, and it supports speeds of 30-800 mm/s.
A screw-tunable needle at both ends traps a small air volume to decelerate the piston near the stroke extremes. You adjust it to match your load and speed, reducing end-cover impact and vibration. It is strictly a deceleration device, not a brake or load lock.
