About the Airtac B52-MD Copper-Free Multi-Position Locking Cylinder B52-MD20X40S
The AirTAC MD20X40S is a compact multi-mount cylinder with a square body that can be fixed from 6 directions: front, back, left, right, top and bottom. Bodies can also be mounted side by side, so tight machine layouts waste less space, and magnetic-switch slots run around the body for easy switch placement. This version is double acting with a 20 mm bore and 40 mm stroke, giving about 157.1 N of theoretical push at 0.5 MPa, with a bumper providing the cushioning. Air filtered to 40 um is the working medium, proof pressure is 1.5 MPa (215 psi), and operating pressure is 0.15-1.0 MPa (22-145 psi).
This is a genuine AirTAC part in the standard MD family (rotation of the rod is not prevented; see the MK family for no-rotating versions). The trailing S in the code means this SKU carries a built-in magnet for magnetic switch detection. Operating temperature is -20 to 70 C, or up to 150 C only with the optional high-temperature seal material. We confirm dimensions, weight and sizing details from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Pick the bore for the force you need: at 0.5 MPa this 20 mm bore delivers about 157.1 N on the push side (the push side is higher than the pull side), and operating pressure spans 0.15-1.0 MPa. Choose MD if rod rotation is acceptable, or the MK family if the rod must not turn. Acting type options are double acting (MD), single-acting push (MSD), single-acting pull (MTD), double rod (MDD) and adjustable stroke (MDJ).
This SKU is 40 mm stroke, well within the 60 mm maximum for a 20 mm bore double-acting cylinder; note the short covers mean an over-long stroke is best avoided. The trailing S adds the magnet. Air ports are M5x0.8, with PT thread as standard on this SKU or G as an alternative (as on the MD20X40SH). If your application applies side loads, confirm allowable values with us from the datasheet.
Applications
Small-parts clamping
Bolt the square body top or bottom to a fixture and use the 20 mm bore, about 157.1 N of push at 0.5 MPa, to clamp small parts in place during assembly or machining.
Conveyor gate and stopper
Fix the body from the side of a conveyor line and extend the 40 mm stroke to stop or divert products between stations, with the bumper softening each stop.
Jig positioning
Mount several MD20X40S units side by side on a jig to position workpieces repeatably, with the built-in magnet (trailing S) carrying position switches around the body.
FAQ
What does the S at the end of MD20X40S mean?
The trailing S means this SKU includes a built-in magnet, so reed or solid-state magnetic switches can detect piston position in the slots around the body. The same cylinder without an S, such as MD20X40, has no magnet; it is an option, not a standard feature.
How many ways can I mount this cylinder?
The multi-mount body can be fixed from 6 directions: front, back, left, right, top and bottom. Units can also sit side by side to save space. Overall dimensions depend on the stroke, so confirm them from the datasheet before laying out your mounting.
