About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SCA
The AirTAC MBLC63X250SCA is a double-acting, adjustable-air-cushion mini cylinder built around a compact, riveted rolling-packed aluminum barrel. Delivering 1558 N push and 1457 N pull at 0.5 MPa (2181 N push at 0.7 MPa), this 63 mm bore, 250 mm stroke unit handles heavy linear motion in tight spaces. The integrated -S magnet allows CMSG, DMSG, or EMSG sensor switches to track rod position, while the CA pivot back cover swings on a pin to accommodate arcing loads.
Unlike the fixed rubber bumper of the base MBL, this MBLC variant uses a screw-tunable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, protecting the end covers during high-frequency or heavy-mass cycles. The 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal for lasting friction control. Note that the cushion only slows the piston near the ends; it does not lock the rod if air pressure is lost.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SCA Is Used
Automotive Welding Clamp
Drives a heavy spot-welding gun over a 250 mm travel, using the tunable cushion to decelerate the 1558 N thrust before the end of stroke, preventing impact damage during high-frequency robotic welding.
Pallet Transfer Pivot
Uses the CA clevis back cover to swing a heavy diverter arm on a packaging conveyor, absorbing the arcing load while the -S magnet confirms retraction via a DMSG sensor.
Board Stacking Press
Pushes corrugated sheets in a 250 mm stacking cycle, relying on the riveted aluminum barrel and hard-chrome rod to deliver consistent 2181 N force at 0.7 MPa without lateral deflection.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250SCA the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1558 N of push force. If your load requires less force, stepping down to the 50 mm bore yields 981 N push and 881 N pull at the same pressure, offering a more compact footprint. If you need maximum thrust, this is the largest standard MBL/MBLC size available, so you cannot step up further within this series. The 250 mm stroke suits extended travel, but because the 16 mm rod has limited side-load tolerance at that length, you should use an external guide, the CA pivot mount, or an MBLD double-rod cylinder to prevent rod bending. The adjustable air cushion is preferable over the base MBL when moving heavy masses quickly, but for position holding without live air, add an external rod lock or pilot-operated check valve. Replacement match: 63 mm bore, 250 mm stroke, G1/4 port, PT thread, CA back cover, S magnet.

- ✓ 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 MBLC63X250SCA FAQ
This 63 mm bore cylinder delivers 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push and 2040 N pull at 0.7 MPa, with a maximum theoretical output of 318 kgf at 1.0 MPa.
The -S code indicates a built-in magnet compatible with CMSG reed and DMSG/EMSG electronic sensors for position detection. The cushion is a screw-tunable pneumatic needle at both ends that decelerates the piston near stroke limits to reduce impact; it is not a braking lock and cannot hold the rod if air supply is removed.
