The Quadboss 414289 QBS Bearings are high-performance skate bearings designed for use in quad skates. These bearings are precision machined to ensure optimal balance, speed, and durability. The inner and outer races are made from hardened steel, providing a strong foundation for the bearing elements.
The ball retainer is a unique Quadboss design, called the Quad Ring, which is a flexible yet supportive cage that holds the balls in place while allowing for free movement. This design reduces the chance of ball contact with the raceways, leading to less friction and smoother rolling.
The Quadboss 414289 QBS Bearings feature ABEC-7 precision bearings, which means they meet or exceed the standards set by the Annular Bearing Engineers Committee. These bearings have a tighter tolerance for axial play and radial runout, resulting in less wobble and more accurate wheel alignment.
The bearings come with shields pre-installed, which protect the bearings from dirt and debris while still allowing for easy maintenance. The shields are also designed to minimize air resistance, helping to maintain optimal speed.
The Quadboss 414289 QBS Bearings are suitable for use in a variety of quad skate styles, including jam skates, roller derby skates, and recreational quad skates. They are also suitable for use in inline skates with the use of an adapter.
In summary, the Quadboss 414289 QBS Bearings are high-performance skate bearings designed for use in quad skates. They are precision machined for optimal balance, speed, and durability, and feature a unique Quad Ring retainer design for reduced friction and smoother rolling. They meet or exceed ABEC-7 precision standards and come with pre-installed shields for protection and easy maintenance.
