Single, non-contact, removable rubber shield for easy cleaning and less friction
High speed nylon ball retainer for greater strength and speed
Pre-lubricated with Speed Cream racing lubricant
Bones Bearings products have a lifetime warranty which protects them against manufacturing defects.
This unique design features six larger diameter balls instead of seven. The advantage is higher speed, quicker acceleration, greater strength and durability
Bones Super Swiss 6 bearings (SS6) are fundamentally different from our famous Bones Swiss. Super Swiss have 6, 3/16 inch balls instead of 7, 5/32 inch balls. Thus, the SS6 balls are 20% larger and roll fewer times to go the same distance. Like bigger wheels on a car, they create less rolling friction and have a higher top speed. SS6's special design and Swiss quality materials enable it to accelerate quicker, roll faster, and resist the impact of skate trick landings better than standard designs.

Thin-section crossed roller bearing ,because of its vertical arrangement of tapered roller with a 90°V in the deep groove roller surface ,compared to other kinds of bearings has increased rigidity to a large extent .A set of crossed roller bearing can support radial load, axial load and loading moment from all directions .At the same time, the inner and outer ring dimensions of the bearing were miniaturized as much as possible. Especially for the extremely thin is access to the limit. It can be used in, such as, the arthritis or the rotary location of the industry robots, rotary working table of the machine work center, revolution location of machine hand , accurate rotary working table , medical machinery , dispensing mechanism , and IC manufacturing installation
