The AirTAC Airtac MK Series Multi-position Locking Cylinder MK16X25 is a genuine MK multi-mount cylinder (double acting), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 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.
The MK16X25 is an AirTAC MK series multi-mount cylinder with a 16 mm bore and 25 mm stroke. Its square body fixes from 6 directions (front, back, left, right, top and bottom) so units can be bolted side by side to save space, with magnetic-switch slots machined around the body. As a double acting MK cylinder it delivers about 100.5 N of theoretical push force at 0.5 MPa on this bore, and the built-in bumper cushions the stroke at each end.
This is a genuine AirTAC part. The MK family is the no-rotating version: a fixed rod and plate stop the piston rod from turning, unlike the standard MD series where the rod is free to rotate. This SKU is supplied without a magnet (no S suffix) and with PT thread ports (M5x0.8 on this bore). Dimensions and sizing for your fixture can be confirmed 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.
Choose the 16 mm bore when your clamp or positioner needs roughly 100.5 N theoretical push at 0.5 MPa (about 86.4 N on the pull side); step up to 20, 25 or 32 mm for more force. Pick MK over MD when rod rotation must be prevented; MD is the standard type when rotation is acceptable. This is a double acting unit, and the 25 mm stroke sits within the bore 16 table (up to 50 mm) - keep strokes modest, as the short covers do not suit over-long strokes. There is no magnet on this SKU (choose the S suffix for one), and thread is PT; G is available as an option. Confirm side-load limits from the datasheet or ask us.
Side-by-side MK16X25 cylinders grip small parts in a fixture, with the no-rotating rod keeping the clamp pad square to the workpiece.
Fixes from 6 directions so the body can be mounted vertically or laterally inside a welding or assembly jig to position parts precisely.
Extends and retracts a stopper or gate on a conveyor line, with the bumper cushioning each end of the 25 mm stroke.
MK is the no-rotating multi-mount family: a fixed rod and plate stop the piston rod from turning, which suits clamping and stopping where the pad must stay square. The MD series is the standard type and its rod is free to rotate. Both mount from 6 directions, and both are double acting in this bore.
The MK16X25 runs on filtered air at 0.15-1.0 MPa with a bumper cushion, but overall dimensions vary with the stroke and allowable side-load is not published as a simple figure. Confirm both from the datasheet before designing your fixture, or ask us and we will route the details to you.
