About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X15-10
The AirTAC MBLCJ20X15-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a screw-tunable air cushion at both ends. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The 10 mm rear adjuster allows you to trim the 15 mm nominal stroke down to a 5 mm usable window, providing exact end-position tuning for very tight travel spaces. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses adjustable air cushioning to decelerate the 8 mm chrome-plated carbon-steel rod at the stroke extremes, absorbing impact without bouncing. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure consistent lubrication across the 30-800 mm/s speed range. Remember that the rear stopper sets the travel end and the cushion only decelerates; neither component mechanically locks or holds the load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X15-10 Is Used
Micro-actuation in textile looms
The 157 N push force and 5-15 mm adjustable stroke window are ideal for guiding delicate yarn threads in compact weaving machinery where exact travel limits prevent fiber snagging.
Small parts ejection in PCB testers
Tunable air cushioning allows the 8 mm rod to retract smoothly without bouncing, protecting fragile printed circuit boards during automated functional test fixture cycling.
Wire cutting feed mechanisms
Operating at speeds up to 800 mm/s, the 220 N force at 0.7 MPa provides rapid, precise wire feeding adjustments in compact electronic cable cutting machines.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X15-10 the Right Cylinder?
With a 20 mm bore generating 157 N of push force at 0.5 MPa, stepping up to the 25 mm bore increases output to 245 N, while stepping down is not possible as this is the smallest available size. Choose this MBLCJ over the MBLJ when your application requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need the 10 mm rear travel adjustment to dial in the 5-15 mm stroke window. The overall length equals A + 2 x 15 + 10, and mounting is limited to Basic, FA flange, or LB foot styles as there is no back-cover or SDB pivot option.
For a direct replacement, match the 20 mm bore, 15 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and the absence of a magnet. Note that the rear adjuster is a travel stop, not a mechanical lock, so external load-holding mechanisms are required if position retention is needed when air pressure is removed.
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 MBLCJ20X15-10 FAQ
At 0.5 MPa, this 20 mm bore cylinder generates 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N, with a maximum theoretical output of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the -S designation, meaning it is manufactured without a built-in magnet and cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches for rod position detection.
