About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X350-50S
The AirTAC MBLCJ50X350-50S is a compact, double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 50 mm of travel, creating a usable stroke window of 300 to 350 mm for precise end-position tuning.
Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable air cushion on this model lets you regulate end-of-stroke deceleration, protecting the end covers during fast, heavy movements. The -S code indicates a built-in magnet for position detection using CMSG reed or DMSG and EMSG electronic sensors. The 20 um hard-chrome plated carbon-steel rod and grease-retaining piston seal ensure long service life, though the 350 mm stroke on a Ø16 mm rod means an external guide is recommended to prevent side-load bending.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X350-50S Is Used
Injection Mold Ejection
Handles the 350 mm extraction stroke for injection-molded automotive interior panels, using the 50 mm bore's 981 N push force and tunable cushion to prevent part scuffing during rapid ejection.
Textile Beam Lifting
Raises heavy textile warp beams into the creel window, utilizing the 300-350 mm adjustable stroke range to perfectly align the beam journals with the receiving brackets.
Palletizer Diverter
Actuates a diverter arm on a end-of-line palletizer, where the adjustable air cushion absorbs the rotational inertia of the 200 kgf maximum load class at cycle ends.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X350-50S the Right Cylinder?
If 881 N of pull force is insufficient, step up to the Ø63 bore, which provides 1457 N of pull force at 0.5 MPa; if you need less force, step down to the Ø40 bore, which offers 528 N of pull. Choose the MBLCJ over the MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper impact, or choose the MBLC if you require a fixed standard stroke without the rear adjuster. Remember that the rear adjuster is a mechanical travel stop, not a lock, and the air cushion only decelerates; neither will hold a load in place without live air pressure. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. For a direct replacement, match the 50 mm bore, 350 mm stroke, 50 mm adjust code, G1/4 port, PT thread, 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 MBLCJ50X350-50S FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The rear stroke adjuster physically limits the piston's travel, giving you a usable window of 300 to 350 mm. The adjustable air cushion is a separate screw-tunable valve that controls the rate of deceleration near the stroke end. The adjuster acts as a travel stop, not a lock, and the cushion only decelerates; neither mechanism will hold a load in place without continuous air pressure.
