About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SCA
The AirTAC MBLC63X350SCA is a double-acting, 63 mm bore aluminum mini cylinder with a 350 mm stroke. It delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it the highest-thrust variant in the MBL family. 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 to smoothly decelerate the heavy 318 kgf maximum load near each stroke end, cutting end-cover impact, noise, and vibration on fast moves.
This specific SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. The CA back cover provides a pivot/clevis mount that swings on a pin to accommodate arcing angular loads. At 350 mm of travel, the Ø16 mm carbon-steel rod (with 20 µm hard-chrome plating) has a low side-load tolerance, so the CA pivot is essential for preventing rod bending. The riveted rolling-packed aluminum barrel keeps the body compact and light rather than using a rebuildable tie-rod design.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SCA Is Used
PCB Conveyor Diverters
Drives angular swinging gates on SMT conveyor lines, using the 1558 N force and CA pivot to smoothly route heavy PCB pallets without side-loading the rod.
Pallet Stacking Arms
Actuates rotary lifting arms in end-of-line palletizers, where the tunable cushion absorbs the 318 kgf maximum load impact at the end of the 350 mm travel.
Bottling Line Pushers
Transfers heavy glass beverage containers between belts, relying on the DMSG electronic sensor to confirm the extended position at high cycling speeds.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SCA the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1558 N push and 1457 N pull. If your application requires less force, the next size down is the 50 mm bore, which yields 981 N push and 881 N pull. Because 63 mm is the largest bore in the MBL/MBLC range, there is no larger standard size available to step up to. Choose this MBLC over the fixed-bumper MBL when your machine cycles at high frequency or moves a heavy mass at speed, where a standard bumper would wear out or crack from the impact.
For the 350 mm stroke, the small Ø16 mm rod is highly susceptible to side-load bending and deflection. You must manage this load using the CA pivot clevis, an external linear guide, or by switching to an MBLCD double-rod cylinder to prevent premature seal failure. The replacement match for this unit is: 63 mm bore, 350 mm stroke, G1/4 port, PT thread, CA pivot back cover, and -S magnet. Note that the adjustable air cushion only decelerates the piston near the ends; it does not hold position if air 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 MBLC63X350SCA FAQ
This 63 mm bore cylinder provides 1558 N push and 1457 N pull at 0.5 MPa. At 0.7 MPa, it yields 2181 N push and 2040 N pull. The maximum theoretical force is 318 kgf at 1.0 MPa.
The CA back cover is a clevis that swings on a pin, allowing the cylinder to follow arcing loads without bending its 16 mm rod during the 350 mm stroke. The adjustable air cushion at both ends is screw-tuned to decelerate the piston smoothly, protecting the end covers from impact on heavy moves, but it does not lock the rod in place.
