Genuine AirTAC magnetic rodless cylinder, order code RMH16X500S from the RMH range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The RMH16X500S reaches the 500 mm ceiling of the 16 mm RMH bore, the longest travel this size offers. Its slide rides on the built-in guide rail while a magnetic couple transfers piston force through the sealed tube wall, giving rodless motion in a body far more compact than an equivalent rod cylinder of the same stroke.
Because 500 mm is the longest lever in this bore, load derating matters most here: the coupling holds 140 N and the load table's 3 kg and 5 kg ratings apply to a 300 mm stroke, falling beyond that, so confirm the payload against the extended-stroke figures in the datasheet. Ports are M5x0.8 on one side, pressure is 0.2-0.7 MPa with 1.2 MPa (175 psi) proof, speed runs 50-400 mm/s, and the 251-800 mm tolerance band makes the stroke +1.5 / 0 mm.

No other 16 mm order code travels further than RMH16X500S; RMH16X450S and RMH16X400S shave 50 and 100 mm off the length. If the move must exceed 500 mm you change bore: RMH20 and RMH25 reach 800 mm with PT1/8 ports and 220 N or 345 N couplings. Within 16 mm, pick this code only when the full 500 mm envelope is genuinely needed and the derated load still clears your payload.
Moves a part or gripper across a 500 mm span on an assembly station, the maximum reach available in the 16 mm bore.
Raises and lowers a light load in a lift station, using the guide rail to resist rotation over the tall 500 mm travel.
Indexes a dispensing head across bins spaced along a 500 mm track, with EMSH or CMSH switches reading position from the built-in magnet.
16 mm bore, 500 mm stroke (the maximum for this bore, tolerance +1.5 / 0 mm), magnetic holding force 140 N, double acting with built-in guide rail and magnet, M5x0.8 ports, 0.2-0.7 MPa operating pressure, 1.2 MPa (175 psi) proof pressure, 50-400 mm/s speed, -20 to +70 C.
The load table gives 3 kg or 5 kg up to a 300 mm stroke and the allowed load falls on longer strokes, so at 500 mm the derating is at its strongest for this bore. Keep the applied force below the 140 N coupling limit, and if end-of-stroke impact is harsh, order the separately available hydraulic shock absorbers to replace the fixed cushions.
