About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160SCA
The AirTAC MBLC20X160SCA is a compact double-acting aluminum mini cylinder engineered for tight-assembly automated motion. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, making it well-suited for 160 mm travel tasks like indexing small electronic jigs or actuating lightweight gripper carriages. The riveted rolling-packed aluminum barrel keeps the body light and spatially efficient, fundamentally differing from bulky rebuildable tie-rod constructions.
Unlike the base MBL bumper design, this MBLC variant features a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, absorbing kinetic energy to protect the end covers on fast, repetitive cycles. The CA pivot back cover swings on a pin to accommodate arcing loads, while the built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensor switches for precise position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160SCA Is Used
PCB Router Transfer
Shifts populated PCB panels between conveyor lanes with 157 N of push force, relying on the adjustable air cushion to stop the 160 mm travel smoothly without jarring delicate solder joints.
Pick-and-Place Arm
Drives a small vacuum gripper carriage for SMD component handling, where the CA pivot absorbs angular misalignment and the -S magnet triggers a DMSG sensor for exact pick coordinates.
Lab Dispenser Indexing
Actuates a rotary indexing table for vial filling, using the tunable end-cushioning to decelerate the repetitive 160 mm stroke quietly without metal-on-metal impact.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160SCA the Right Cylinder?
When sizing this 20 mm bore, step down is not an option as it is the smallest available frame. If you need more force, the 25 mm bore provides 245 N of push at 0.5 MPa. Choose this MBLC over the standard MBL when your cycle speed or frequency exceeds what a fixed rubber bumper can safely absorb. The CA clevis mount is ideal here for arcing articulation, but note that a plain MBLC does not hold position if air pressure drops; the cushion only decelerates near the ends rather than locking the rod.
This replacement unit matches the following exact configuration: 20 mm bore, 160 mm stroke, G1/8 port, PT (tapered) thread, M8x1.25 rod-end thread, CA pivot back cover, and a built-in magnet for CMSG/DMSG/EMSG sensors. Because the stroke is 160 mm, the 8 mm rod has limited tolerance for side-loading; use an external guide rail to prevent rod bending and premature seal wear.
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 MBLC20X160SCA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, push increases to 220 N and pull to 185 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It uses an 8 mm carbon-steel rod with an M8x1.25 end thread.
The MBLC20X160SCA features a screw-tunable pneumatic cushion at both ends. You adjust the needle valve to trap a pocket of exhaust air, decelerating the piston smoothly before it hits the end cover. This is critical for high-frequency cycles, as it reduces impact noise and wear far better than a fixed rubber bumper, but it does not function as a load lock.
