About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SCA
The AirTAC MBLC20X150SCA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering 157 N of push force and 132 N of pull force at 0.5 MPa, it is designed for lighter payloads requiring smooth deceleration. The 150 mm stroke provides ample travel for small-part transfer, while the riveted rolling-packed aluminum barrel keeps the body light and compact for tight machinery envelopes.
This variant includes a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. The built-in magnet (-S) enables position detection using AirTAC CMSG, DMSG, or EMSG sensor switches. Inside, a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod ensure reliable friction control across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SCA Is Used
PCB Pick-and-Place Arcing
Ideal for electronics assembly arms where the CA pivot accommodates slight arcing during 150 mm travel, while the cushion softens rapid pick-and-place moves without jarring delicate boards.
Lightweight Divert Gate
Drives a small sorting flap on a packaging conveyor; the 157 N thrust at 0.5 MPa easily pushes light cartons, and the tunable needle prevents harsh slamming at high cycle rates.
Sensor Actuation Arm
Moves a testing probe into position using the -S magnet to trigger a DMSG electronic switch, ensuring precise 150 mm extension before the cushion gently decelerates the mechanism.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SCA the Right Cylinder?
Select this 20 mm bore when an application demands 157 N of thrust at 0.5 MPa alongside a 150 mm stroke with angular pivot capability. If your move is slow and light, the base MBL with its fixed rubber bumper is sufficient; choose the MBLC specifically when faster cycling or heavier masses require tunable end-of-stroke deceleration to prevent end-cover impact. Stepping up to the 25 mm bore increases thrust to 245 N at 0.5 MPa, while stepping down is not an option as 20 mm is the smallest available size. Note that the adjustable cushion only decelerates the piston near the stroke ends—it is not a brake and will not hold the load if air pressure is lost.
For replacement or system matching, verify the G1/8 port, M8x1.25 rod-end thread, PT thread form, CA pivot back cover, and the integrated -S magnet. Because the 150 mm stroke is relatively long for an Ø8 mm rod, side-load tolerance is low; ensure external guidance is used to prevent rod bending, or consider an MBLD double-rod cylinder if rotational stability is required.

- ✓ 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 MBLC20X150SCA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, push increases to 220 N and pull to 185 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It uses a G1/8 port and an M8x1.25 rod thread.
The cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover. You tune it to match the load and speed, which cuts noise and vibration on fast moves. It is strictly an end-of-stroke damper, not a load lock or brake.
