Linear guide

A linear guide, comprising:

• a profiled body extending along an axis of movement;
• and
• a carriage which is mounted on the profiled body such that it can move linearly along the axis of movement,
• wherein the carriage has a rolling bearing unit, which bears with at least one rolling element against a guideway,
• wherein the guideway has two guide rails which are arranged in a row along the axis of movement and which are each positively received on the profiled body in spatial directions aligned transversely to the axis of movement,
• wherein mutually opposite end faces of the two guide rails delimit an abutment region, and
• wherein a material connection region is formed between the respective guide rail and the profiled body in each case adjacent to the abutment region, wherein the material connection region extends over a maximum of 10 percent of a total length of the respective guide rail along the axis of movement and in which a material connection is formed between the guide rail and the profiled body.
