About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100S
The AirTAC MBLCJ25X100-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The 100mm adjustment code allows you to trim the full 100mm nominal stroke, yielding a usable travel window of 0-100mm. Delivering 245 N of push force at 0.5 MPa, this G1/8 ported bore is built for dynamic mid-range positioning tasks.
Unlike the base MBLJ which relies on a fixed rubber bumper, the screw-tunable air cushion on this unit allows you to regulate end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during faster moves. The built-in magnet (-S) enables compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensors for precise position feedback. Remember the rear stopper sets the travel end but does not lock the load; you will need an external guide to prevent rod bending on this Ø10 mm piston rod.

| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100S Is Used
PCB Drill Spindle Stop
Uses the 0-100mm window to set precise Z-axis drill depth on a PCB routing machine, relying on the 245 N push force and tunable air cushion to prevent hard cover impacts.
Textile Loom Tensioner
Adjusts the guide arm position dynamically on a textile loom, using the magnetic -S feedback and screw-tunable deceleration to handle rapid thread tensioning changes.
Bottle Capping Head
Drives a capping head in a beverage packaging line, trimming the stroke via the rear stopper to accommodate different bottle heights without changing the cylinder.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100S the Right Cylinder?
If your application requires less force, stepping down to the 20mm bore yields 157 N of push at 0.5 MPa, whereas stepping up to the 32mm bore provides 402 N. Choose this MBLCJ over the MBLJ when your cycle speeds demand tunable end-cushioning rather than a fixed rubber bumper, or over the MBLC when you need to restrict the travel window. The rear adjuster is a travel stop, not a mechanical lock, so the rod will drift if air is removed. Mounting is limited to Basic, FA (flange), or LB (foot) configurations as there is no back-cover or SDB pivot option. To match this exact replacement, verify: 25mm bore, 100mm stroke, 100mm adjust code, G1/8 port, PT thread, and the -S 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 MBLCJ25X100-100S FAQ
At 0.5 MPa, this 25mm bore 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, with an operating pressure range of 0.15-1.0 MPa.
The 100mm adjustable stroke uses a rear stopper to physically limit the travel window from 0 to 100mm, setting where the rod ends its movement. The adjustable air cushion uses a screw to tune the deceleration rate near the end of that stroke to absorb kinetic energy. Neither the stopper nor the cushion acts as a lock, so the rod will drift if air pressure is lost.
