About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-40S
The AirTAC MBLCJ50X225-40S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers a robust 981 N push force at 0.5 MPa. The rear stopper allows you to trim up to 40 mm of travel, creating a usable stroke window of 185-225 mm for precise end-positioning. An integrated magnet (-S) enables position detection.
Unlike the fixed rubber bumper found on an MBLJ, this model's screw-tunable air cushion decelerates heavy loads near the stroke ends, protecting the end covers from impact damage. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod withstand demanding cycles. Remember that the rear adjuster is a travel stop, not a mechanical lock; it sets the end point but does not hold the load in place without live air pressure.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-40S Is Used
Injection Mold Extraction
Provides the 981 N pull force needed to extract heavy plastic parts from injection molds, using the 185-225 mm adjustable window to time the exact handoff to the robot arm.
Woodworking Clamp Press
Tunes the end-of-stroke air cushion to decelerate a heavy woodworking clamp press, preventing sudden impact shocks from cracking the aluminum end covers.
Pallet Dispenser Feed
Pushes empty pallets into a packaging line, relying on the built-in magnet to trigger a DMSG solid-state sensor for a fast cycle signal at high speeds.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-40S the Right Cylinder?
Select this 50 mm bore when your application requires the 981 N push force at 0.5 MPa. If you need less force, step down to the 40 mm bore (628 N push); if you require more power, step up to the 63 mm bore (1558 N push). The 225 mm stroke is well within the 500 mm maximum standard stroke for this bore, keeping the unit compact. For exact replacements, match the 50 mm bore, 225 mm stroke, 40 mm adjust code, G1/4 port, PT thread, basic mounting, and the -S magnet.
Choose the MBLCJ over the MBLJ when your moving mass demands tunable end-of-stroke deceleration rather than a fixed rubber bumper. Choose it over the MBLC if your machine setup needs a variable travel endpoint. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; no SDB pivot or back-cover options exist. Because the stroke is 225 mm, the 16 mm rod is susceptible to side-load bending—use an external guide rail to prevent cylinder damage. Neither the cushion nor the adjuster acts as a brake to hold a suspended load.
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 MBLCJ50X225-40S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa operating pressure.
The rear adjuster is a mechanical travel stop that sets your usable stroke window between 185 and 225 mm. The air cushion is a screw-tunable valve that decelerates the piston near the end caps. Neither holds the load in place without continuous air pressure.
