The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X50-30 is a genuine double-acting aluminum-barrel mini cylinder with a Ø50mm bore, a 50mm nominal stroke and a rear adjustable-stroke stopper — trim up to 30mm for a usable window of 20–50mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ50X50-30 is a double-acting, single-rod mini cylinder featuring a riveted aluminum barrel and a robust Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. It delivers 981 N of push force at 0.5 MPa and uses a G1/4 port. A rear stopper allows you to trim up to 30 mm of travel, creating a usable stroke window of 20-50 mm for precise end-position tuning.
Unlike the fixed rubber bumper found on the MBLJ series, this model incorporates a screw-tunable adjustable air cushion at both ends to manage deceleration for heavier loads. The overall length follows the A + 2 x stroke + adjust formula, meaning the 30 mm trim adds to the total footprint. Because this specific SKU lacks the -S magnet code, it cannot support CMSG, DMSG, or EMSG position sensors.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.

Provides 981 N of push at 0.5 MPa to break heavy plastic parts loose from molds, using the 20-50 mm adjustable window to dial in the exact ejection height.
Uses the tunable air cushion to smoothly slow the 881 N pull force when seating copper windings, preventing wire deformation during the final 30 mm of travel.
Holds printed circuit boards firmly for routing operations, where the compact riveted body fits tight machine cavities and the stopper sets a precise 45 mm clamp depth.
For tasks needing less force, stepping down to the Ø40 bore yields 628 N of push at 0.5 MPa, whereas moving up to the Ø63 bore provides 1558 N. Choose the MBLCJ over the MBLJ when your moving mass requires regulated end-of-stroke deceleration to protect the end covers, or pick the MBLC if you need fixed standard stroke lengths. The rear adjuster sets the travel end, and the cushion only decelerates; neither component locks the load, so external holding mechanisms are required for position retention. Mounting is restricted to Basic, FA, or LB styles, as there is no back-cover or SDB pivot option. A direct replacement requires a 50 mm bore, 50 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and no magnet.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
This specific SKU lacks the -S code, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensors. The rear adjuster trims travel by up to 30 mm, giving a usable window of 20-50 mm. This mechanism acts only as a travel stop, while the separate adjustable air cushion handles end-of-stroke deceleration; neither holds the load.
