About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-75S
The AirTAC MBLCJ25X225-75S is a compact double-acting mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa. The 75 mm rear trimmer allows you to dial the usable stroke window down from 225 mm to a 150 mm minimum, providing flexibility for varying machine format changes without swapping the entire cylinder body.
This unit includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensors to track rod position. Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable air cushion on this SKU decelerates heavier loads at the stroke extremes, protecting the aluminum end covers. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod resist wear, though the 10 mm rod requires external guidance to prevent side-load bending over this 225 mm travel.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-75S Is Used
PCB Edge Conveyor Stopper
Dialing the 75 mm rear adjuster sets the stopper position for varying board widths on a conveyor line, while the cushion absorbs the 245 N impact to prevent fiberglass damage.
Packaging Flap Folder
Tunes the folding arm travel within the 150-225 mm window for different carton depths, using the DMSG electronic sensor to verify full fold completion before sealing.
Textile Fabric Guide
Positions fabric edge guides across a 225 mm span; the adjustable air cushion slows the rod before striking the end covers, preventing sudden jerks that would tear delicate woven materials.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-75S the Right Cylinder?
With a 245 N push force at 0.5 MPa, stepping down to the 20 mm bore drops output to 157 N, while moving up to the 32 mm bore increases thrust to 402 N. Choose this MBLCJ variant when your application demands precise end-position tuning alongside controlled deceleration; the fixed bumper MBLJ lacks cushion adjustment, and the MBLC type omits the rear travel stopper. Remember that the rear adjuster is a mechanical travel stop, not a lock, and the cushion only decelerates, so neither holds a load in place without live air pressure. Mounting is limited to Basic, FA flange, or LB foot brackets, as this series does not offer SDB pivot or back-cover options. For a direct replacement, match the 25 mm bore, 225 mm stroke, 75 mm adjust code, G1/8 PT port, 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 MBLCJ25X225-75S 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, with a maximum theoretical output of 50 kgf at 1.0 MPa.
The 75 mm rear adjuster is a mechanical travel stop that sets your usable stroke window between 150 and 225 mm. The adjustable air cushion is a separate screw that tunes end-of-stroke deceleration. Neither holds a load in place; they only control travel and speed.
