The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X100-10S is a genuine double-acting aluminum-barrel mini cylinder with a Ø20mm bore, a 100mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 90–100mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ20X100-10S is a compact double-acting mini cylinder featuring a single Ø8mm carbon-steel rod and a lightweight riveted aluminum barrel. It delivers 157N of push force and 132N of pull force at 0.5 MPa. The rear stroke adjuster allows you to trim up to 10mm of travel, providing a usable positioning window of 90-100mm. This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches to confirm rod position.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant incorporates a screw-tunable adjustable air cushion at both ends. This mechanism allows you to dial in the end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during faster cycling. The riveted rolling-packed barrel construction and heterogeneous two-way grease-retaining piston seal ensure consistent lubrication over the 30-800mm/s speed range, while the 20um hard-chrome plating resists wear in abrasive environments.

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.

Feeds a circular saw blade at a precise 95mm stroke using the 90-100mm adjustment window, relying on the 157N push force and tunable air cushion to halt the blade smoothly without stressing the aluminum frame.
Actuates a micro-dosing valve for adhesive application, using the built-in magnet with a DMSG electronic sensor to confirm the 100mm full extension, while the cushion screw prevents fluid splashing from sudden stops.
Ejects small plastic moldings from a press, utilizing the 132N pull force at 0.5 MPa to retract the Ø8mm rod, while the adjustable stroke allows a 5mm retraction trim to avoid striking the mold half.
The 20mm bore generates 157N push force at 0.5 MPa, making it ideal for light-duty positioning. If your application requires less force, there is no smaller standard MBL bore, so you would reduce operating pressure. If you need more power, stepping up to the 25mm bore yields 245N of push force at 0.5 MPa. Choose the MBLCJ over the MBLJ when your dynamic loads require tunable deceleration rather than a fixed impact stop, or over the MBLC when you need to fine-tune the end position by up to 10mm.
Remember that the rear adjuster acts purely as a mechanical travel stop, not a load-holding lock; the rod will drift if air pressure is removed, so an external guide or lock is required for position holding. Mounting is limited to Basic, FA flange, or LB foot styles, as this series omits the SDB pivot and back-cover options. The overall length equals A plus 2 times stroke plus the 10mm adjuster. This specific SKU uses a standard PT (tapered) port thread and G1/8 port size. Replacement matches: 20mm bore, 100mm stroke, 10mm adjust code, PT thread, Basic mounting, with an S magnet.
Quick checklist
At 0.5 MPa, this 20mm bore cylinder provides 157N of push force and 132N of pull force. At 0.7 MPa, the push force increases to 220N. The maximum theoretical force is 32 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The adjustable stroke is a rear mechanical stopper that trims the rod travel within a 90-100mm window, setting the exact end position. The adjustable air cushion is a separate screw-tunable valve that controls the rate of deceleration near the stroke ends to prevent harsh impacts. Neither mechanism locks or holds the load in place without continuous air pressure.
