As we all know, roller gliders have a maximum weight limit, which, if it is exceeded, will cause them to quickly break. One day, CINO Ole Stilling was playing with his grandson’s Fidget Spinner. He got the idea to use the small steel ball bearing in the middle of the spinner in a roller glider. The result was our new 8020 roller glider, with two ball bearings fitted with a rubber ring. The steel ball bearings ensure that the 8020 can be subjected to an extreme amount of weight. The rubber fitting ensures that the wheel will always rotate and that the roller glider runs silently.
