The AirTAC MBL Aluminum Alloy Mini Cylinder MBL20X100U is a genuine double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 100mm stroke, 1/8" air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL20X100U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 157 N of push force and 132 N of pull force over a 100 mm stroke, making it suitable for precise small-part actuation.
Unlike tie-rod bodies, this unit features a riveted rolling-packed barrel where the covers are crimped to the tube, creating an ultra-light, permanently sealed assembly that is not designed to be disassembled. This specific U-coded SKU has a rigid flat-end rear cover for fixed mounting, and because it lacks the -S suffix, it cannot accept a CMSG or DMSG position sensor.

Pushes finished printed circuit boards out of test fixtures using 157 N of force without stressing delicate traces.
Actuates a small paddle to sort lightweight cartons on a packaging line within a confined 100 mm stroke envelope.
Moves a rack of test tubes precisely 100 mm between analysis stations in compact diagnostic equipment.
If you need less force, stepping down is not an option as 20 mm is the smallest MBL bore; stepping up to the 32 mm bore yields 402 N of push force at 0.5 MPa. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts, so for faster cycling with heavier loads, consider the MBLC variant which adds an adjustable air cushion. Note that this cylinder cannot hold a load if air pressure is lost; the rod will drift, requiring an external pilot-operated check valve for position holding. At a 100 mm stroke, the Ø8 mm carbon-steel rod offers reasonable support, but always ensure the rigid U back cover is squarely mounted to avoid binding.
Quick checklist
At 0.5 MPa, the 20 mm bore provides 157 N push and 132 N pull force. At 0.7 MPa, push increases to 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It operates at 30-800 mm/s on filtered air with a G1/8 port.
This specific SKU lacks the -S magnet, so it cannot accept CMSG or DMSG electronic switches for position detection. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable air cushion; choose the MBLC variant if you need cushion adjustment.
