About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SU
The AirTAC MBLC63X250SU is a double-acting aluminum mini cylinder engineered for heavy-duty compact automation. It delivers a robust 1558 N push force at 0.5 MPa, utilizing a 63 mm bore and a 250 mm stroke to drive sizable loads in confined footprints. The integrated -S magnet enables direct position feedback, seamlessly supporting AirTAC CMSG reed and DMSG or EMSG electronic solid-state sensor switches for precise end-of-stroke detection.
This model distinguishes itself from the standard MBL by incorporating a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needles allows you to smoothly decelerate the piston near stroke extremes, significantly cutting end-cover impact, mechanical noise, and vibration during high-speed or high-mass cycles. The riveted rolling-packed aluminum barrel keeps the body light yet durable, while the 20 um hard-chrome plating on the carbon-steel rod defends against wear and corrosion.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SU Is Used
Pallet Diverter Arm
Drives a heavy routing arm on a packaging conveyor, using the 250 mm stroke to shift boxed goods between lanes while the adjustable cushion absorbs the 1558 N stopping force smoothly.
Injection Mold Ejector
Provides consistent 1457 N pull force to retract an ejection plate in a plastic molding cell, relying on the DMSG electronic sensors to confirm full retraction before the mold closes.
Warehouse Vertical Lift Gate
Actuates a 250 mm safety gate on an automated storage retrieval system, where the tunable air cushion prevents harsh slamming that could damage delicate inventory or misalign the gate tracks.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SU the Right Cylinder?
Selecting this 63 mm bore makes sense when your application requires substantial thrust—1558 N push and 1457 N pull at 0.5 MPa—within a compact envelope. If you need less force and a smaller footprint, stepping down to the 50 mm bore yields 981 N of push force. Conversely, if you require maximum output, this is the largest standard MBL/MBLC size available, pushing 2181 N at 0.7 MPa with a theoretical 318 kgf ceiling at 1.0 MPa. Choose this MBLC variant over the fixed-bumper MBL when moving heavy payloads at high cycling frequencies that would prematurely wear a standard rubber bumper.
With a 250 mm stroke, the Ø16 mm piston rod is susceptible to bending under lateral stress; always use an external guide rail to support the load. The U flat-end back cover provides rigid rear mounting. For exact replacement matching, verify the G1/4 port, PT tapered thread form, U back cover, and the -S magnet. Note that the adjustable air cushion only decelerates the rod near the ends; it is not a brake, and the cylinder will drift if air pressure is lost or the valve centers.
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 MBLC63X250SU FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push increases to 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod with an M14x1.5 thread, and operates at speeds between 30 and 800 mm/s.
The MBLC63X250SU features screw-adjustable pneumatic cushions at both stroke ends. By turning the needle valve, you trap a small amount of exhaust air to decelerate the piston before it hits the end cover. This is essential for protecting the cylinder on fast, heavy moves, unlike the base MBL which relies on a fixed rubber bumper. It only decelerates near the ends and does not lock the rod in place.
