KOGEL BEARINGS bottom bracket BSA for SRAM DUB | Cross Seal's pottery
The people at Kogel Bearings believe that high-quality ceramic bearings are the benchmark for bicycle bearings.
Silicon nitride has a number of material properties that make it almost perfect for bicycle bearings.
The material is extremely hard, wear resistant, can be formed into perfectly round balls with minimal tolerances, and can be polished smoother than any metal. In addition, the material will not rust or corrode in any other way.
The bearing rings are made of hardened steel and polished. This is necessary to create a perfect, smooth running surface for the ceramic balls.
Kogel Bearings offers two different types of seals for different applications: Road Seals, a minimal contact seal designed to run as smoothly as possible.
The Cross Seals, on the other hand, are designed for extra protection against external elements: dust, water and mud. It is ideal for CX, MTB or road bike use if maximum service life is important.
Kogel Bearings is aware that ceramic bearings have a bad reputation for durability. This is mostly due to the suboptimal quality of the bearings being sold as a high one.
A bearing must be designed and manufactured in a balanced way: the degree of hardness of the balls must be combined with equally smooth and hard bearing tracks. Bearing cage, seals and grease must be matched to work perfectly.
If one of the components does not fit perfectly, it reduces the performance of the entire bearing. The result is increased resistance, reduced service life or even total bearing failure.
To prove that Kogel Bearings believe in their products, they guarantee that the bearings will run flawlessly for at least 2 years.
If something breaks in the first year, Kogel will repair or replace the product with no questions asked.
A service must be carried out after the first year. If the bearing is serviced by a qualified mechanic, i.e. cleaning, relubrication and replacement of the seals,
the guarantee is extended by another year.
