Generally, "bearings" facilitate movement between two parts and reduce friction. A typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.
Bearing mounting methods depend on the bearing type and type of fit. As bearings are usually used on rotating shafts, the inner rings require a tight fit. Bearings with cylindrical bores are usually mounted by pressing them on the shafts (press fit) or heating them to expand their diameter (shrink fit).
The 6902 bearing is a common bearing model widely used in industries such as bicycles, electric bicycles, automobiles, and household appliances. It belongs to the most extensively used category of bearings in the mechanical industry. In this article, we will delve into the dimensions of the 6902 bearing.
In wet and muddy environments, selecting suitable bearings is critical for electric bike performance. Ceramic, stainless steel, and sealed bearings are viable options. Ceramic bearings offer strong corrosion resistance, while stainless steel bearings resist corrosion and sealed bearings prevent water and contaminants.
ISK Bearings participated in TAIPEI CYCLE 2025, showcasing a range of bicycle-specific bearings, including customizable solutions, hub bearings, and ceramic series. Through on-site demonstrations and customer interactions, we highlighted our stable supply capabilities and professional support. Missed the show? Feel free to reach out for an online consultation.
They possess characteristics such as magnetic insulation, resistance to wear, corrosion, and high temperatures, as well as the ability to operate without lubrication. These features make them particularly suitable for applications requiring high temperatures and corrosion resistance.
