On this application, the aim is to change from the left-hand side of a cast mold to the right-hand side with as little effort as possible. For this purpose, the two compartments on the mold must be rotated 180 degrees with the utmost precision. The bearings used must be lubricant-free, as quartz sand is used here, which would get stuck to the lubricant. The iglidur® PRT slewing ring bearing masters this job brilliantly, is lighter and in terms of purchasing is cheaper than a comparable metal rotary connector.
