About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250SCA
The AirTAC MBLC20X250SCA is a compact double-acting aluminum mini cylinder engineered for tight spaces. It delivers 157 N of push force at 0.5 MPa and features a 250 mm stroke, making it well-suited for lighter-duty positioning tasks. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø8 mm carbon-steel rod with 20 µm hard-chrome plating resists wear. The heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over long cycles.
This variant includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing loads. A built-in magnet (-S) allows CMSG (reed) or DMSG/EMSG (electronic) sensor switches to detect rod position. Unlike the base MBL, this MBLC model uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, cutting impact noise and vibration on faster moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250SCA Is Used
PCB Depaneling Saw Feed
Drives a light cutting blade carriage across 250 mm to singulate printed circuit boards, using the CA pivot to tolerate minor carriage arc while the cushion prevents end-jarring.
Pick-and-Place Z-Axis
Raises and lowers a small vacuum gripper for electronic chip placement, relying on the 157 N push force and the tunable cushion to stop smoothly at 250 mm.
Carton Flap Deflector
Pivots a light guide flap on packaging lines to redirect small cartons, using the CA clevis to absorb angular load while cycling at high frequency.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X250SCA the Right Cylinder?
At 0.5 MPa, this 20 mm bore generates 157 N push and 132 N pull. If your application requires less force, there is no smaller standard MBL bore, so you would look outside the mini-cylinder range. If you need more power, stepping up to the 25 mm bore yields 245 N push at 0.5 MPa. Choose this MBLC over the fixed-bumper MBL when your cycle speeds are high enough that the rubber bumper cannot adequately absorb the kinetic energy.
The 250 mm stroke on an Ø8 mm rod means side-load tolerance is low; for arcing or off-center loads, the CA pivot cover is essential to prevent rod bending. Note that the adjustable air cushion only decelerates the piston near the ends—it is not a lock. If you must hold position without live air, fit an external rod lock or pilot-operated check valve. This exact replacement match requires a 20 mm bore, 250 mm stroke, G1/8 port, PT thread, CA back cover, and the -S magnet.

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 MBLC20X250SCA FAQ
At 0.5 MPa, it provides 157 N push and 132 N pull force. At 0.7 MPa, it provides 220 N push and 185 N pull. The maximum theoretical force is 32 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
A screw-tunable needle at both stroke ends traps a pocket of air to decelerate the piston before it hits the cover. You adjust it to match the load and speed, which reduces impact, noise, and vibration. It functions purely as a deceleration device, not a load lock or brake.
