Bones Labyrinth

This is a new bearing similar to the original Bones Swiss bearing, with a re-designed inner race and two labyrinth seals. These seals are non-contact and float in a groove machined in the inner race to ensure there is no added friction. Double labyrinth non-contact, removable rubber shields allow easy cleaning and ultra low friction. High speed nylon ball retainer provides added speed and strength. Skate Rated clearances, tolerances, materials and lubricant provide the best performance and durability possible.
