About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160CA
The AirTAC MBLC20X160CA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable air cushion at both ends. Generating 157 N of push force at 0.5 MPa, this 20 mm bore unit is tailored for lighter loads that need smooth deceleration over a 160 mm stroke. The riveted rolling-packed aluminum barrel keeps the body light and tight for cramped machine layouts, while the 20 µm hard-chrome plating on the carbon-steel rod defends against wear.
Configured with a CA pivot back cover, this cylinder swings on a pin to accommodate arcing angular loads rather than binding rigidly. The heterogeneous two-way grease-retaining piston seal maintains lubrication for a long service life. Note that this specific SKU lacks a built-in magnet, meaning it cannot support a CMSG, DMSG, or EMSG sensor switch for position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160CA Is Used
PCB Shuttle Routing
Drives a 160 mm routing path for PCB panels in electronics assembly, using the tunable cushion to prevent jarring stops that could misalign delicate surface-mount components.
Pick-and-Place Arm
Actuates a lightweight vacuum pick-and-place arm for chip placement, where the CA pivot absorbs angular moments during rapid retraction over the 160 mm travel.
Pouch Diverter Gate
Pivots a small diverter gate on a packaging conveyor, using the 157 N push force at 0.5 MPa to redirect lightweight pouches smoothly without impact.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160CA the Right Cylinder?
When sizing this 20 mm bore model, stepping down is not an option as it is the smallest available size. If you need more force, step up to the 25 mm bore, which provides 245 N of push at 0.5 MPa. Choose this MBLC over the base MBL when your cycle speeds or moving masses outpace what a fixed rubber bumper can absorb. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a locking mechanism, so the rod will drift if air pressure is lost. The direct replacement match for this SKU requires a 20 mm bore, 160 mm stroke, G1/8 port, PT thread, CA pivot back cover, and no magnet. Because the stroke is 160 mm, the 8 mm rod has limited side-load tolerance, so utilizing the CA pivot is highly recommended to prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160CA FAQ
This 20 mm bore cylinder delivers a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, it provides 220 N of push and 185 N of pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
The MBLC20X160CA features a screw-tunable pneumatic cushion at both ends. You adjust the needle to match your load and speed, decelerating the piston smoothly near the stroke ends to cut impact noise and vibration, which is superior to a fixed rubber bumper on faster cycles.
