Rotating Die Holders

Rotating Die Holders – Rotating Die Box. Rotating die holders are a very easy way to increase productivity and reduce die wear on wire drawing lines. The rotating die holder itself is continuously being cooled by means of re-circulating water around the die seating surface as the die rotates around the wire during the wire drawing operation.

Bearings are used between the rotating and stationary parts of turbomachinery. Ball and roller bearings are commonly used in turbine engines. These bearings require an oil lubrication system that provides a thin film of oil between the moving parts of the bearing. Without oil, the metal-to-metal contact would cause the engine to grind to a halt.

Roll Coating

The simplest roll coating set-up uses a single rotating roller. The bottom half of the roller is immersed in a coating liquid bath and the upper part of the roller is in contact with the fabric substrate (Fig. 10.7).As it rotates, the coating liquid forms a film on the roller surface and part of the liquid film is transferred from the roller surface to a fabric substrate.

Your explanation about the flat spot is helpful, but let's imagine we have 2 steel wheels ( alone ) on the rail track for example . It's not made of rubber, so I think the flat spot may not take place here .
