About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75
The AirTAC MBLCJ25X175-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a screw-tunable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The 175 mm stroke combined with the 75 mm rear adjuster creates a usable travel window of 100 to 175 mm, allowing you to dial in the exact end position for variable-length ejection tasks.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model's adjustable air cushion lets you regulate end-of-stroke deceleration to absorb kinetic energy from faster cycling, protecting the end covers. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plated carbon-steel rod provide durable service in tight spaces. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75 Is Used
Textile Loom Let-Off
Regulates tensioning arms in weaving machines, using the 100-175 mm adjustable window to compensate for varying beam diameters while the air cushion softens high-frequency reversals.
Packaging Flap Folding
Drives mechanical flap folders on carton sealers where the 245 N push force securely creases corrugated board and the tunable cushion prevents hard stops that skew alignment.
PCB Conveyor Diverter
Actuates routing gates on SMT lines, using the rear stopper to set precise divert lengths without repositioning the cylinder body, ensuring smooth board transfer.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75 the Right Cylinder?
If you need less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa, whereas stepping up to the 32 mm bore provides 402 N for heavier payloads. Choose this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic damping rather than a fixed bumper, or over the MBLC when you need to trim the travel distance rather than using a fixed stroke. The 75 mm adjuster acts as a mechanical travel stop to set the endpoint, while the cushion only regulates deceleration speed; neither component locks the rod or holds the load, which requires an external guide or locking mechanism. Mounting is limited to Basic, FA, or LB styles, as the MBLCJ series does not offer SDB pivot or back-cover options. To match this exact replacement, specify bore 25, 175 mm stroke, 75 mm adjust, G1/8 port, PT thread, and no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75 FAQ
At 0.5 MPa, this double-acting cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa, operating within a pressure range of 0.15 to 1.0 MPa.
The 75 mm adjustable stroke is a rear mechanical stopper that physically limits the rod travel, creating a usable window of 100 to 175 mm. The adjustable air cushion is a screw-tunable valve that regulates deceleration at the stroke ends. The stopper sets the position, and the cushion controls the speed, but neither acts as a lock to hold the load.
