Product Description:

The MLS300S-3A-0150-HNNN secondary section is a component of the MLS Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. Serving as the passive track inside a linear drive, it carries laminated iron and permanent magnets that interact with a moving primary coil to create controlled linear thrust for industrial positioning stages. It forms part of modular segments that can be lined up to meet custom stroke requirements, allowing travel length to be scaled without redesign. Because the part remains stationary, it anchors directly to the machine bed and transmits reaction forces into the frame.

The mechanical design relies on screw mounting, and the secondary body has a width of 150 mm, which sets the rail footprint that must be kept clear inside the machine base. Its mounting stack reaches an installation height of 61.4 mm, so shims or spacers can align the magnetic centerline with the forcer. Front-to-back depth is 345 mm, including the cover sheet that protects the magnet surface. The 0150 code identifies the segment length, and the aluminum carrier uses M8 through-holes with a recommended tightening torque of 37 Nm. The screws use class 10.9 hardware and follow the DIN EN ISO 4762 socket-head standard, matching common plant assembly tools.

The assembly has a rating of IP65, and the optional cover sheet helps keep contaminants away from the magnet slots even though the unit is not magnetically shielded. Segment density is 70.0 kg/m, while the shipped piece weighs 10.5 kg because the effective length is 0.15 m. A distance plate thickness of 0.95 mm sets the required standoff so the moving forcer maintains an air gap of 1.0 mm (±0.4). Transport eyelets accept M10 threaded lifting bolts, and the S-type secondary classification refers to the 300-size magnet topology used across the series.
