About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SU
The AirTAC MBLC50X450SU is a double-acting, 50 mm bore aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 981 N of push force and 881 N of pull force at 0.5 MPa, this 450 mm stroke unit is built for rapid, heavier traversing where fixed rubber bumpers would fail. The U-coded flat-end back cover provides a rigid rear mount for straightforward in-line anchoring.
A defining feature of this SKU is the built-in magnet (-S), enabling position detection with AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight rather than relying on bulky tie-rods, while the 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SU Is Used
Pallet Transfer Stops
Decelerates a 981 N load at 0.5 MPa smoothly when halting heavy pallets on a 450 mm conveyor indexing line, preventing end-cover shock.
CNC Lathe Bar Feeders
Pushes raw bar stock through a spindle over 450 mm; the DMSG electronic sensor tracks the full extension while the cushion softens the rod return.
Vertical Carton Magazine
Lifts stacked packaging materials using the 881 N pull force at 0.5 MPa, relying on the U flat-end cover for rigid top-frame mounting.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SU the Right Cylinder?
Stepping down, the 40 mm bore neighbor provides 628 N push at 0.5 MPa, which is better for lighter payloads. Stepping up, the 63 mm bore yields 1558 N push at 0.5 MPa for heavier demands. Choose this MBLC over the base MBL when your cycle speeds exceed what a fixed rubber bumper can absorb without slamming. The adjustable air cushion only decelerates the piston near the ends; it is not a load lock. A plain double-acting cylinder will drift if air is lost or the valve centers, so fit an external rod lock or pilot-operated check valve if you need true position holding.
At 450 mm, this stroke approaches the 500 mm standard limit, meaning the Ø16 mm rod is highly susceptible to bending under lateral stress. To manage side-load risks, guide the load externally, use a CA or SDB pivot bracket for arcing motion, or switch to an MBLD double-rod cylinder. Replacement match: 50 mm bore, 450 mm stroke, G1/4 port, M14x1.5 rod thread, PT port thread form, U flat-end back cover, no mounting bracket, magnet fitted.
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 MBLC50X450SU FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends restricts exhaust air to decelerate the piston smoothly near stroke limits. You tune it to match your load and speed, cutting impact, noise, and vibration on fast cycles. It only decelerates near the ends; it is not a brake or load lock.
