A bearing 6300-2RS is a kind of deep groove ball bearing, which is one of the most common types of rolling bearings. It consists of an inner ring, an outer ring, a cage, and a set of balls that are held in place by the cage. The balls enable the bearing to rotate smoothly and reduce friction between the rotating parts. A bearing 6300-2RS has two rubber seals (RS) on both sides of the bearing, which prevent contaminants, such as dust and water, from entering the bearing and also retain the lubricant inside. The rubber seals also have a steel reinforcement to increase their durability. The size of a bearing 6300-2RS is measured by its inner diameter (d), outer diameter (D), and width (B). A bearing 6300-2RS has an inner diameter of 10 mm, an outer diameter of 35 mm, and a width of 11 mm. These dimensions are standardized according to the International Organization for Standardization (ISO) and are expressed as 10x35x11 mm or 35x10x11 mm. A bearing 6300-2RS can support both radial loads (perpendicular to the axis of rotation) and axial loads (parallel to the axis of rotation), but it is mainly designed for radial loads. The maximum speed that a bearing 6300-2RS can rotate depends on the type and amount of lubricant used, but it is generally around 32,000 revolutions per minute (RPM) with grease1. A bearing 6300-2RS is widely used in various applications that require low noise and high speed, such as skateboards, inline skates, scooters, electric motors, bicycles, motorcycles, power tools, and more234.
