About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X10-10
The AirTAC MBLCJ25X10-10 is a compact, double-acting mini round cylinder with a 25 mm bore and 10 mm stroke. It features a rear travel stopper that allows you to trim up to 10 mm at the rear, creating a highly precise 0-10 mm usable stroke window. Driven by air on both sides of the single rod, it delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The riveted aluminum barrel keeps the body light for tight machine spaces.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant incorporates a screw-tunable adjustable air cushion at both ends. This lets you dial in end-of-stroke deceleration for faster cycling without slamming the end covers. Note that this specific SKU lacks a built-in magnet (-S), so it cannot host a CMSG, DMSG, or EMSG position sensor. The rear stopper sets the travel end and the cushion only decelerates; neither mechanism locks or holds the load in place without live air pressure.

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)

| 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 MBLCJ25X10-10 Is Used
PCB Edge Connector Seating
Provides 245 N of push force to gently press gold-fingers into backplane connectors, using the 0-10 mm stroke adjustment to perfectly set insertion depth without stressing the board.
Label Dispenser Tamp
Tunes the air cushion to softly tamp labels onto pharmaceutical cartons at high speed, preventing bounce while the narrow 10 mm stroke delivers rapid retraction.
Thin Sheet Metal Flange
Flattens thin stainless steel flanges on HVAC duct fittings, where the 206 N pull force retracts the rod cleanly through the 0-10 mm window without bowing the material.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X10-10 the Right Cylinder?
With a 245 N push force at 0.5 MPa, this 25 mm bore is a solid middle ground. If your payload is lighter, stepping down to the 20 mm bore drops the output to 157 N push. If you need more thrust, the 32 mm bore raises it to 402 N. Choose the MBLCJ over the MBLJ when your cycle speed demands tunable cushioning rather than a fixed bumper, or over the MBLC when you need that rear stroke adjustability to dial out a 0-10 mm over-travel.
For an exact replacement, match the 25 mm bore, 10 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and Basic mounting (no FA/LB). Remember the adjuster is a travel stop, not a brake, so external load-holding is required if power drops. Mounting is limited to Basic, FA, or LB; there is no SDB pivot or back-cover option on this chassis.
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 MBLCJ25X10-10 FAQ
At 0.5 MPa, this 25 mm bore cylinder outputs 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, with a proof pressure of 1.5 MPa.
This specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The 10 mm rear adjuster is a travel stop that sets the end position, and the adjustable air cushion only decelerates the piston; neither feature locks or holds the load without continuous air pressure.
