About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175SU
The AirTAC MBLC20X175SU is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering a push force of 157 N and a pull force of 132 N at 0.5 MPa. Driven by a Ø8 mm carbon-steel rod with 20 um hard-chrome plating, this 175 mm stroke variant is ideal for lighter automation tasks requiring extended reach. The riveted rolling-packed aluminum barrel keeps the body light while maintaining structural integrity.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC model features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to decelerate the piston smoothly near each stroke end, cutting end-cover impact and vibration on faster cycles. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for rod position detection, while the U flat-end back cover provides a rigid rear mount.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175SU Is Used
PCB Depaneling Router
Extends 175 mm to position a routing bit over large circuit panels, using the adjustable air cushion to decelerate the approach smoothly and avoid jarring the delicate fiberglass substrate.
Small Parts Ejector
Pushes lightweight plastic caps off a conveyor line with 157 N of force, relying on the tunable cushion to minimize end-of-stroke impact noise during high-frequency cycling.
Test Socket Actuator
Moves 175 mm to lower an electronics test probe onto a chip, using the -S magnet with a DMSG solid-state sensor to confirm the extended position before high-voltage testing begins.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175SU the Right Cylinder?
Choose this 20 mm bore when you need 157 N of push force at 0.5 MPa in a compact footprint. If your application requires less force, there is no smaller standard MBL bore; however, if you need to step up, the 25 mm bore provides 245 N of push force. Select the MBLC over the standard MBL when your cycle speeds are high enough that the fixed rubber bumper would wear prematurely or cause excessive impact noise. Remember that the adjustable cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure is lost.
For replacement matching, verify the 175 mm stroke, G1/8 port, PT thread form, U flat-end back cover, and the built-in -S magnet. Because the stroke is 175 mm, the relatively small Ø8 mm rod has a higher susceptibility to side-loading and bending under off-center loads; using an external guide rail or ensuring perfectly axial load alignment is critical to prevent premature seal wear.
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 MBLC20X175SU FAQ
At 0.5 MPa, this 20 mm bore cylinder provides a push force of 157 N and a pull force of 132 N. At 0.7 MPa, the push increases to 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses an 8 mm diameter carbon-steel rod with an M8x1.25 rod-end thread and a G1/8 port.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston before it hits the end cover, reducing impact on fast moves; it does not lock the rod. Because this SKU includes the -S magnet, you can fit AirTAC CMSG reed switches or DMSG and EMSG electronic solid-state sensors for position detection.
