Airtac MD Multi-Position Clamping Cylinder MD20X70
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD20X70 is a genuine MD multi-mount cylinder (double acting), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MD Multi-Position Clamping Cylinder MD20X70
The MD20X70 is an AirTAC MD-series multi-mount cylinder: a compact square-body, double acting actuator with a 20 mm bore and 70 mm stroke that fixes from six directions - front, back, left, right, top and bottom - so cylinders can be mounted side by side to save space. At a typical 0.5 MPa supply it produces about 157.1 N of theoretical push force for light clamping and positioning work, with a bumper cushioning the stroke, and magnetic-switch slots are provided around the body.
This is a genuine AirTAC part in the standard MD family, where limited rod rotation is acceptable. The model code carries no trailing S, so this SKU is supplied without the magnet. Note that 70 mm exceeds the standard double-acting stroke table for a 20 mm bore (up to 60 mm), so please confirm this stroke and all dimensions with us from the datasheet before ordering.

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
The 20 mm bore gives about 157.1 N of push (131.9 N pull) at 0.5 MPa; choose 25 or 32 mm bores for higher thrust or 6-16 mm for lighter loads. MD allows a little rod rotation - select the MK family when the rod must not turn. Acting choices span double acting (MD), single push (MSD), single pull (MTD), double rod (MDD) and adjustable stroke (MDJ). Standard double-acting strokes for bore 20 run to 60 mm; the 70 mm stroke on this SKU is beyond that table, so confirm availability with us rather than assuming, and remember the short covers caution against over-long strokes. Codes with S add the magnet; thread is PT as default, or G on request.
Applications
Press-fit light assembly
Bolt the cylinder through its side or base faces into a compact bench fixture to press small components together, relying on the 157.1 N push force available at 0.5 MPa.
Slide indexing on fixtures
Fix the square body from the top or rear of a machine plate so multiple units line up side by side, each advancing a slider through its 70 mm stroke between index positions.
Part push-off station
Use the six-way mounting to fit the cylinder at the end of a small parts track and push finished pieces off the line, with the bumper absorbing the end-of-stroke impact.
FAQ
Is a 70 mm stroke standard for a 20 mm bore MD cylinder?
The standard double-acting stroke table for the 20 mm bore runs up to 60 mm, so the 70 mm stroke on this model is above the listed range. Please contact us to confirm availability and dimensions from the datasheet before specifying it - the short covers of the multi-mount body also caution against stretching the stroke unnecessarily.
How does the six-direction mounting help in a tight machine?
The square MD body can be fixed from any of six faces - front, back, left, right, top and bottom - so the cylinder bolts into the orientation your layout needs, and several units can sit side by side to save space. Exact body dimensions and allowable side-load figures should be confirmed from the datasheet for your mounting case.
