Genuine AirTAC magnetic rodless cylinder, order code RMH16X300S from the RMH range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
AirTAC gives the RMH16X300S a Dia 16 mm bore, a 300 mm stroke and M5x0.8 ports. Magnetic coupling drives the slide with no rod, the piston chamber is isolated from the slide to keep dirt out, and the added guide rail raises running accuracy, anti-rotation accuracy and load capacity. Catalog holding force for Dia 16 is 140 N.
This stroke marks the end of the full-load case: the catalog allows 3 or 5 kg up to 300 mm, so at exactly 300 mm you still have the complete rated load. Above 250 mm the stroke tolerance widens to +1.5/0 mm. Operate it on air filtered to 40 um at 0.2-0.7 MPa and 50-400 mm/s from -20 to +70 C, with CMSH, DMSH or EMSH sensors in the groove.

At 300 mm this is the longest Dia 16 stroke that keeps the full 3/5 kg load rating. Choose RMH16X300S over RMH16X250S only when that extra 50 mm matters and the wider +1.5/0 mm tolerance is acceptable. Compared with RMH16X350S, this code avoids the load derating that begins past 300 mm; if you need more travel or higher force, step to the Dia 20 RMH20 series with its PT1/8 ports and 220 N holding force.
Pushing or shifting diverters and stops on conveyor lines, where a 300 mm throw covers the full divergence with 140 N of coupling force.
Feeding components into fixtures at up to 400 mm/s on air filtered to a 40 um element, with sensor switches confirming each position.
Carrying up to 5 kg across 300 mm where the slide must not rotate, staying inside the envelope where the full load case still applies.
Dia 16 mm bore, 300 mm stroke, 140 N magnetic holding force, M5x0.8 ports, double acting with guide rail, 0.2-0.7 MPa operating pressure, 50-400 mm/s speed, -20 to +70 C, stroke tolerance +1.5/0 mm above 250 mm, and the full 3/5 kg load case valid to exactly 300 mm.
The catalog permits 3 or 5 kg up to 300 mm for Dia 16, so this code sits at the last stroke with the full rating; beyond it the allowed load falls. Also keep the working force below the 140 N holding force, and check the 1.2 MPa (175 psi) proof pressure in the datasheet.
