About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-50S
The AirTAC MBLCJ25X100-50S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The 50 mm adjustment code lets you trim the rear travel, creating a usable stroke window of 50 to 100 mm. This tunable end-of-stroke cushioning absorbs kinetic energy to protect the end covers, a step up from the fixed rubber bumper found on the base MBLJ series.
This SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed switches or DMSG and EMSG solid-state electronic sensors. The Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring, while the heterogeneous two-way grease-retaining piston seal maintains lubrication for high cycle rates. The riveted rolling-packed aluminum barrel keeps the overall body compact for tight machinery spaces. Remember that the rear stopper sets the travel end; it does not hold the load, and the cushion only decelerates—neither acts as a mechanical lock.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 MBLCJ25X100-50S Is Used
PCB Routing Machine
Drives an X-axis router carriage across a 50-100 mm window, using the tunable air cushion to prevent end-impact vibration that could skew trace accuracy.
Bottle Capper Head
Lowers a spindle onto plastic caps; the 245 N push force seats caps firmly while the rear adjuster dials the exact 80 mm down-stroke for varied bottle heights.
Textile Yarn Guide
Shifts a yarn guide rapidly across a loom; the DMSG electronic sensor tracks the rod position while the cushion slows the traverse to protect the end caps.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-50S the Right Cylinder?
When sizing this 25 mm bore cylinder, compare its 245 N push force at 0.5 MPa with the 20 mm bore (157 N) if your payload is lighter, or step up to the 32 mm bore (402 N) for heavier loads. Choose the MBLCJ over the MBLJ when your application requires screw-tunable deceleration to handle faster cycling or heavier masses without slamming the covers. The rear adjuster is strictly a travel stop, not a lock; the rod will drift if air is removed. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option for this series. For an exact replacement, match the 25 mm bore, 100 mm stroke, 50 mm adjust code, G1/8 port, PT thread, and the -S magnet specification.
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 MBLCJ25X100-50S FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The 50 mm adjustable stroke is a rear travel stopper that sets your usable end position between 50 and 100 mm. The adjustable air cushion is a separate screw that tunes end-of-stroke deceleration. Neither holds the load if air pressure is lost.
