About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50SU
The AirTAC MBLC32X50SU is a double-acting mini cylinder engineered for compact actuation, delivering 402 N of push force at 0.5 MPa. It features a 50 mm stroke and a built-in magnet (-S) for compatibility with CMSG reed and DMSG or EMSG electronic sensor switches to track rod position. Unlike the base MBL, this variant utilizes a screw-adjustable pneumatic air cushion at both stroke ends to smoothly decelerate the piston, actively protecting the rigid U flat-end back cover from impact damage during rapid cycling.
Constructed with a riveted rolling-packed aluminum barrel, the body remains lightweight and suited for tight machinery spaces. The 12 mm carbon-steel rod features a 20 µm hard-chrome plating to resist wear, paired with a heterogeneous two-way grease-retaining piston seal that maintains lubrication over long service hours. The cushion needle is easily tuned to match the specific load and speed of your application, ensuring quiet, vibration-free stops without acting as a position lock.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50SU Is Used
PCB Depaneling Saw
Drives a circular blade at 402 N push force to singulate printed circuit boards, using the tuned air cushions to halt the 50 mm stroke gently and prevent micro-fractures in the substrate.
Carton Flap Folder
Folds minor flaps on high-speed packaging lines, relying on the 346 N pull force and U flat-end rigid mounting to maintain trajectory while avoiding harsh end-of-stroke jerks.
Connector Insertion Press
Pushes IC connectors into sockets with exact 50 mm travel, using the DMSG electronic sensor to confirm insertion while the adjustable cushion prevents crushing delicate pins.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the 25 mm model reduces push force to 245 N at 0.5 MPa, while stepping up to the 40 mm bore increases it to 628 N. Choose the MBLC over the standard MBL when operating at high cycling frequencies where a fixed rubber bumper cannot adequately absorb the kinetic energy of heavier loads. For replacement, match the 32 mm bore, 50 mm stroke, G1/8 port, M10x1.25 rod thread, PT thread form, U flat-end back cover, and the built-in magnet. Note that the 50 mm stroke is short enough to minimize rod bending, but the 12 mm rod still has low side-load tolerance, requiring external guides if pushing off-center loads.
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 MBLC32X50SU FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force reaches 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa operating pressure.
The cushion needle is screw-tunable at both ends to decelerate the piston smoothly near the 50 mm stroke limits. You adjust it to match the load and speed, which cuts impact noise and vibration on the end covers. It only decelerates near the ends and does not lock or hold the rod if air pressure is lost.
