About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175U
The AirTAC MBLC25X175U is a compact double-acting aluminum mini cylinder engineered for a 175 mm stroke. It utilizes a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating to deliver 245 N of push force and 206 N of pull force at 0.5 MPa. Because this configuration omits the -S magnet, it cannot host a CMSG, DMSG, or EMSG sensor switch for end-of-stroke detection.
Distinguishing it from the base MBL, this model incorporates a screw-adjustable pneumatic cushion at both ends rather than a fixed rubber bumper. This allows you to tune the end-of-stroke deceleration to match your load and speed, effectively absorbing impact energy on rapid traverses. The riveted rolling-packed aluminum barrel keeps the body light and tight for cramped machine spaces, while the U flat-end back cover provides a rigid rear mounting plane.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175U Is Used
PCB Depaneling Saw
Drives a circular saw blade to singulate printed circuit boards, using the tunable cushion to soften the 175 mm extension stop and prevent vibration from skewing the cut.
Wafer Cassette Elevator
Raises a semiconductor wafer cassette between process stations, relying on the 245 N push force and adjustable end-cushioning to halt the 175 mm lift without jarring the wafers.
Pharmaceutical Carton Flap Folder
Folds lower cardboard flaps on a packaging line, where the compact riveted barrel fits tight transfer-clearances and the cushion prevents cover impact on fast cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175U the Right Cylinder?
When sizing this 25 mm bore, you can step down to the 20 mm bore for lighter tasks (yielding 157 N push at 0.5 MPa) or step up to the 32 mm bore when more power is needed (providing 402 N push at 0.5 MPa). The MBLC is preferred over the MBL when cycle speeds are high and the fixed bumper cannot adequately absorb the kinetic energy of heavier masses. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake, and the rod will drift if air is lost. For this 175 mm stroke, the 10 mm rod has limited side-load tolerance, so guiding the load externally or using a pivot bracket is recommended to prevent rod bending. Your replacement match: 25 mm bore, 175 mm stroke, G1/8 port, PT thread, U back cover, no magnet.
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 MBLC25X175U FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It uses a G1/8 port, a Ø10 mm rod, and an M10x1.25 rod-end thread.
No, this specific SKU lacks the -S code, meaning no built-in magnet is fitted. To use AirTAC CMSG reed or DMSG/EMSG electronic sensor switches, you must select an MBLC25X175S variant instead.
