The AirTAC Airtac MK Series Multi-position Locking Cylinder MK16X50S 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 MK16X50S is a compact square-body multi-mount cylinder from AirTAC's MK family: a double acting, no-rotating cylinder with a 16 mm bore and 50 mm stroke, fitted with a magnet as the S in the code shows. The body fixes from six directions (front, back, left, right, top and bottom) and mounts side by side to save space, with magnetic-switch slots around the body for position sensing. At 0.5 MPa this 16 mm bore gives about 100.5 N of theoretical push force, and the bumper cushions the piston at end of stroke.
This is a genuine AirTAC part. The MK family adds a no-rotating plate, brass bushing and fixed rod that stop the rod from turning, unlike the standard MD family where rotation is allowed, which matters when the rod carries an aligned tool or pin. The magnet in this SKU lets you detect piston position with suitable switches. We confirm exact dimensions, materials and sizing 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.
Bore drives thrust: the 16 mm bore delivers 100.5 N push (86.4 N pull) at 0.5 MPa in double acting format; choose 20 or 25 mm bores for more force. MK stops rod rotation while standard MD allows it. Acting options across the family are double (MK), single push (MSK), single pull (MTK), double rod (MKD) and adjustable stroke (MKJ). The 50 mm stroke is the maximum in the bore 16 table; the short cover cautions against going longer without checking with us first. The trailing S means this SKU includes the magnet; the version without S omits it. Thread is PT as standard, G as the alternative, with M5x0.8 ports on this bore. Side-load figures and dimensions come from the datasheet, so confirm those with us.
Index a workpiece fixture between stations where the pin must not twist. The magnet lets sensors confirm end-of-stroke position, while the six-direction body fixing suits cramped fixture plates.
Push parts off or stop them in a conveyor lane with a rod that stays rotation-free. Mounting cylinders side by side keeps the control footprint small along dense line sections.
Clamp small machined or electronic parts in a compact workholder. The no-rotating rod keeps clamp pads square to the part, and 100.5 N push at 0.5 MPa covers light holding jobs.
Yes. The trailing S in the code means this cylinder ships with a built-in magnet, so the piston position can be detected by suitable switches in the slots around the body. The otherwise identical MK16X50, without the S, comes without a magnet. Both are double acting, no-rotating cylinders with a 16 mm bore and 50 mm stroke.
A plate, brass bushing and fixed rod stop the rod from turning, so attached pins, gates or clamp pads keep their orientation through every cycle. That suits alignment-critical jobs on jigs, stoppers and pick-and-place heads. For stroke limits, side-load capacity and exact dimensions, confirm from the datasheet.
