First Claim
Patent Images
1. A linear motion device, comprising a rod, a traveler which is movably supported on said rod with at least one roller body circuit, said traveler including an electrically conductive carrier body;
- roller bodies braced on said electrically conductive carrier body in a load-transmitting fashion; and
at least one electrically nonconductive guidance component for unloaded roller bodies of said roller body circuit, said guidance component being provided with an RFID tag, said RFID tag being not accessible from outside, wherein said RFID tag is located between said guidance component and said carrier body.
