About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-100S
The AirTAC MBLCJ50X500-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and dual adjustable air cushions. It delivers 981 N of push force at 0.5 MPa. The rear stopper trims up to 100 mm of travel, creating a precise 400-500 mm usable stroke window for long-range tasks. Tuning the end-of-stroke needle valves decelerates heavy loads smoothly, preventing end-cover damage that a fixed bumper cannot absorb.
This SKU includes a built-in magnet for CMSG, DMSG, or EMSG sensor switches. It uses a G1/4 port, a Ø16 hard-chrome plated carbon steel rod, and a grease-retaining piston seal. The overall length extends by the adjustment range. Because the rod is only 16 mm across a 500 mm span, external guiding is critical to prevent side-load bending and premature seal wear.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-100S Is Used
Pallet Transfer Pusher
Drives loaded pallets along a 450 mm conveyor section. The 981 N push force handles heavy timber pallets, while the air cushion decelerates the 500 mm stroke to prevent impact slamming.
Textile Beam Lifter
Raises heavy textile warp beams into a loom loading cradle. The 400-500 mm adjustable window allows exact height positioning without custom spacers, using the -S magnet to confirm placement.
Packaging Folder Arm
Actuates a large corrugated box folding arm. The 100 mm rear stroke adjustment fine-tunes the fold depth precisely, while the needle valves tune end-deceleration for fast cycling.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-100S the Right Cylinder?
Choose this 50 mm bore for 981 N push at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore (628 N push); for heavier drives, step up to the 63 mm bore (1558 N push). Unlike the MBLJ which relies on a fixed rubber bumper, this MBLCJ lets you screw-tune the end cushions for high-speed 500 mm moves. Unlike the MBLC, it adds the 400-500 mm rear stroke adjuster.
Remember the adjuster is a mechanical travel stop, not a lock; it will not hold a load without live air pressure. Mounting is limited to Basic, FA flange, or LB foot brackets—no SDB pivot or back-cover options exist. For a direct replacement, match the 50 mm bore, 500 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and the -S magnet. Always pair long strokes with an external guide to protect the 16 mm rod.
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 MBLCJ50X500-100S FAQ
At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force is 1374 N. The maximum theoretical force is 200 kgf at the 1.0 MPa operating pressure limit.
The 100 mm rear adjustment is a mechanical travel stop that sets your usable stroke window between 400 mm and 500 mm. The adjustable air cushion only controls end-of-stroke deceleration. Neither feature locks or holds the load in place without continuous air pressure.
