<p>The submersible bath roller comprises a roller body (2), which extends along a longitudinal axis (A), and cylindrical bearing pins (3) for cooperating with bearing bushes for bearing the submersible bath roller. Each cylindrical bearing pin has grooves (4), which extend over the entire circumference of the bearing pins in a circumference direction and are filled by using a protective layer (41) produced by thermal injection. The adjacent grooves are separated by a web (5), which forms 30% of the surface of the bearing pins. Each web has a width (B1) of 3-15 mm, and a width (B2) of 3-20 mm.

Each groove has a depth (T) of 100-200 micrometer. The protective layer is provided in addition to the webs, where the protective layer on the surface of the web has a thickness of 50-100 micrometer. An independent claim is included for a method for producing a roller for a submersible bath with liquid metal.</p> |
