Airtac MKD Multi-position Clamping Cylinder MKD25X25S
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD25X25S is a genuine MK multi-mount cylinder (double rod), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKD Multi-position Clamping Cylinder MKD25X25S
The MKD25X25S is a compact, square-bodied multi-mount cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. Magnetic-switch slots surround the body, guide precision is high and no added lubricant is needed. As a double rod (MKD) variant, it has a rod on both ends of the piston, so it can clamp, press or sense from either side of the body. This 25 mm bore with a 25 mm stroke produces 245.4 N of theoretical push thrust at 0.5 MPa (double-acting push figure for this bore), and the cushion is a bumper.
This is a genuine AirTAC part from the no-rotating MK family, where a fixed rod, plate and brass bushing prevent the rod from turning. The trailing S on this SKU means the magnet option is included, so switch detection is available in the body slots. We confirm exact dimensions 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
Match the bore to the thrust: this 25 mm bore provides 245.4 N theoretical push (206.2 N pull) at 0.5 MPa; verify another bore's figure in the datasheet before changing size. MKD gives you two working rod faces on a rotation-free body, standard MK one, and MD permits rotation. The 25 mm stroke is well within the 60 mm limit for 20/25/32 mm bores, but the short covers make very long strokes impractical; check the datasheet for your length.
This SKU includes the magnet (trailing S), so it pairs with the body's switch slots for end-position sensing. Ports are M5x0.8 on this bore, PT thread by default or G thread to order. Allowable side load is not quoted here; confirm it with us from the datasheet.
Applications
Gripping fixture for small housings
The double rod drives jaws from both sides of the fixture, the no-rotating plate keeps the grip square, and the magnet confirms clamp completion.
Pick-and-place end effector stop
Bolted from the top or bottom of a compact gripper plate, the cylinder retracts a stop pin; switch signals in the body slots time the handoff.
Slide-table locating pin
Mounted side by side on a slide table, the rotation-free rod retracts a locating pin into a bushing with no twisting, stroke after stroke.
FAQ
What does the S in MKD25X25S mean when selecting this cylinder?
The trailing S means this SKU is supplied with the magnet option, so magnetic switches can be fitted in the slots around the body to signal end positions. The identical cylinder without the S (MKD25X25) comes without a magnet; the magnet is optional on MD/MK, never standard on every unit.
Is a very long stroke possible on this short multi-mount body?
No. The short covers of the MD/MK compact body make over-long strokes impractical; for 25 mm bores the stroke table tops out at 60 mm. This model is 25 mm, safely inside the range. Confirm the exact stroke-length dimensions for your build from the datasheet.
