About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X60-10S
The AirTAC MBLCJ20X60-10S is a compact double-acting mini cylinder featuring a riveted aluminum barrel and an Ø8mm hard-chrome plated carbon-steel rod. It delivers 157N of push force and 132N of pull force at 0.5 MPa. Equipped with a built-in magnet (-S), it supports CMSG reed switches alongside DMSG and EMSG solid-state electronic sensors for precise end-position detection.
This model integrates a rear travel stopper allowing you to trim up to 10mm, creating a usable stroke window of 50-60mm. Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant features a screw-tunable adjustable air cushion at both ends. This deceleration mechanism absorbs kinetic energy to prevent end-cover damage during fast cycling. The rear adjuster acts purely as a mechanical travel stop and does not lock or hold the load in place.

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.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X60-10S Is Used
PCB Depaneling Routing
Drives a routing blade with 157N push force at 0.5 MPa, using the 50-60mm stroke window to precisely set the cutting depth and the dual air cushions to halt the blade smoothly without jarring the board.
Micro-Dispense Valve
Actuates a dosing valve in a fluid filling line, relying on the -S magnet to trigger an EMSG solid-state sensor for exact shot timing while the adjustable cushion prevents liquid splashing at stroke ends.
Small Parts Ejector
Pushes lightweight plastic caps out of a molding press, utilizing the 132N pull force for retraction and the tunable end cushions to maintain high 30-800 mm/s cycling speeds without hammering the cylinder covers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X60-10S the Right Cylinder?
At 157N push force, stepping down is not an option as Ø20 is the smallest available bore. If your application requires greater thrust, consider moving up to the Ø25 bore, which provides 245N push and 206N pull at 0.5 MPa. The MBLCJ is ideal when you need both end-position tuning and shock absorption, whereas the MBLJ offers fixed bumper deceleration and the MBLC provides a fixed standard stroke without the rear adjuster.
When ordering a replacement, verify the Ø20 bore, 60mm nominal stroke, 10mm adjustable stroke code, G1/8 port, default PT thread form, and the -S magnet. Mounting is restricted to Basic, FA flange, or LB foot styles; SDB pivot and back-cover configurations are not available. Because the adjuster and air cushion only manage travel and deceleration, an external guide or locking mechanism is required for positive load holding.
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 MBLCJ20X60-10S FAQ
At 0.5 MPa, this Ø20mm double-acting 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 operating pressure.
The rear stroke adjuster is a mechanical travel stop that lets you trim up to 10mm of movement, creating a 50-60mm usable stroke window. The adjustable air cushion separately tunes end-of-stroke deceleration using trapped air. Neither system locks the rod or holds a load in place; live air pressure is required to maintain position.
