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 make sure there is no added friction.

Features
-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.
