About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SCA
The AirTAC MBLC50X15SCA is a double-acting aluminum mini cylinder engineered for compact spaces requiring substantial thrust, delivering 981 N push and 881 N pull at 0.5 MPa. The 15 mm stroke is tailored for short, high-force clamping or ejection tasks. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle valve to decelerate the piston smoothly near stroke extremes, actively reducing impact shock, mechanical noise, and end-cover wear on fast or heavy moves.
This SKU includes the CA pivot clevis back cover, allowing the body to swing on a pin to absorb angular misalignment during arcing motions. It also carries the -S code for a built-in magnet, enabling position detection via AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. The riveted rolling-packed aluminum barrel keeps the overall body lightweight yet structurally rigid, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for low-friction longevity.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SCA Is Used
Stamping Press Ejection
Uses the 981 N push at 0.5 MPa to positively eject small stamped metal parts from a die in a short 15 mm travel, with the tuned cushion absorbing the sudden stop of the heavy stripper plate.
PCB Router Clamping
Secures PCB panels during routing operations; the CA pivot back cover accommodates slight bracket misalignment while the -S magnet confirms clamp engagement via a DMSG solid-state sensor.
Bottle Sorter Deflection
Provides a high-force 15 mm deflection gate on a packaging line to divert fast-moving bottles, relying on the adjustable air cushion to silently decelerate the rapid 30-800 mm/s cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SCA the Right Cylinder?
For applications needing less force, stepping down to the 40 mm bore yields 628 N push at 0.5 MPa, whereas moving up to the 63 mm bore provides 1558 N push if your fixture requires extreme power. Select the MBLC over the standard MBL when your cycle speeds are high or the moved mass is heavy enough that a fixed rubber bumper would degrade too quickly. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake. A plain double-acting cylinder cannot hold position if air pressure drops or the valve centers, so deploy an external rod lock or pilot-operated check valve for fail-safe load holding.
This replacement match features a 50 mm bore, 15 mm stroke, G1/4 port, M14x1.5 rod-end thread, PT (tapered) thread form, CA pivot/clevis back cover, and a built-in magnet (S). Because the stroke is very short, side-load risks are minimal, but the CA clevis is specifically beneficial if your linkage geometry dictates a swinging arc rather than a rigid linear push.
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 MBLC50X15SCA FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull. At 0.7 MPa, it provides 1374 N push. The theoretical maximum force is 200 kgf at 1.0 MPa. It operates at speeds from 30 to 800 mm/s.
The screw-adjustable pneumatic cushion at both ends allows you to regulate the needle valve to match your load and speed, decelerating the piston smoothly near the stroke ends. This protects the end covers from impact shock on heavy, fast moves, whereas a fixed rubber bumper would compress and fail under the same conditions.
