The Bionic Swiss bearings are made from high end materials exclusively. From the Delrin cage to the stainless steel inner and outer rings and on to the titanium balls. All materials chosen for their physical and mechanical abilities.
This means that you get a ball bearing that can stand the test of time, it is extremely easy to service and provide you with effortless roll speed.
The Swiss bearings are lubricated with speed oil eliminating the break-in period you might find with other bearing types.
