About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-50
The AirTAC MBLCJ25X100-50 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a single Ø10 mm carbon-steel rod with 20 µm hard-chrome plating. It combines a rear travel stopper with a screw-tunable air cushion at both ends. The rear adjuster lets you trim up to 50 mm of travel, creating a usable end-position window of 50 to 100 mm. Delivering 245 N of push force at 0.5 MPa, it suits moderate pushing and pulling tasks in tight spaces.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses adjustable end-of-stroke cushioning to decelerate heavier or faster-moving loads smoothly, protecting the end covers. The cushion only controls deceleration and the rear stopper only sets the travel end; neither component acts as a lock to hold a load in place. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors. Mounting is limited to Basic, FA, or LB styles, as no back-cover or SDB pivot options exist for this series.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-50 Is Used
PCB Router Z-Axis
Governs the plunge depth of a compact PCB depaneling router, using the 245 N push force to drive the spindle while the 50-100 mm window allows precise depth trimming without changing mechanical stops.
Bottle Capper Head
Applies consistent downward pressure on plastic bottle caps, utilizing the tunable air cushion to soften the impact at the end of the 100 mm travel and prevent cap distortion.
Textile Y Guide
Positions a yarn tensioning guide in a narrow weaving frame, where the compact riveted barrel fits standard 25 mm bore brackets and the rear stopper sets the exact thread path distance.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-50 the Right Cylinder?
This 25 mm bore generates 245 N push and 206 N pull at 0.5 MPa. If your application needs less force, step down to the 20 mm bore (157 N push), or step up to the 32 mm bore (402 N push) for heavier loads. Choose the MBLCJ over the MBLJ when you need tunable end-deceleration instead of a fixed bumper, or over the MBLC when you require the 50 mm rear stroke adjustment rather than a fixed total travel.
When replacing this cylinder, match the 25 mm bore, 100 mm stroke, 50 mm adjust code, G1/8 port, PT thread, and Basic mounting. Remember that the adjuster is a travel stop, not a load-holding brake; a plain double-acting cylinder drifts under load without live air. An external guide is recommended for this 100 mm stroke to prevent rod bending, as the small 10 mm rod is vulnerable to side loads.
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 MBLCJ25X100-50 FAQ
At 0.5 MPa, this 25 mm 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.
The 50 mm adjuster is a rear travel stopper that lets you set the actual stroke within a 50 to 100 mm usable window. It only defines the travel end point; it does not lock or hold the load. The adjustable air cushion separately tunes the end-of-stroke deceleration rate.
