Product Description:

The Bosch Rexroth Indramat MCS015-3S-0066-NNNN is an ironless linear motor secondary part supplied within the MCS Linear Motors series. Built as the passive track for moving primary coils, it forms the stationary element that closes the magnetic circuit in high-precision positioning axes used throughout industrial automation. The unit follows frame size 015 and uses a U-shaped steel base plate with permanent magnets arranged along its length, a geometry that helps minimize cogging while keeping the profile low. Because it is the passive member of the axis, it does not require separate electrical wiring at the track itself. The secondary part remains fixed during operation while the matching primary element travels above it.

Dimensional data show how the secondary part fits beneath the moving slider. Its active length is 66 mm, while a face width of 66 mm creates a square footprint. With a thickness of only 14.8 mm, the track leaves space for auxiliary cabling inside compact gantries. The individual component weighs 0.2 kg, and the linear density of 3.0 kg/m allows longer assemblies to be estimated from the installed length. Classified as IP00, the element itself provides no ingress protection, so the surrounding machine structure must shield the magnets and mounting surface from contact and contamination. The square planform can also help align the magnet track with compact short-stroke primary elements.

Mechanical retention relies on screws inserted from above; guidance specifies an M4 thread in the mating surface and a property class of 8.8 for the bolts. Each fastener should be tightened to 3.1 Nm so the base plate seats correctly without distortion, while the 9 mm V2 screw-in depth helps prevent interference below the mounting plane. Because the fastening method uses screws, the secondary part can be removed from above when the machine layout is serviced. Top-access fastening is useful where the underside of the mounting plate is enclosed by the machine base. The clearance-hole arrangement also avoids additional machining on the mounting surface.
