6200, 6300 & R Series Ball Bearing Dimensions & Sizes Chart


Bearing is a mechanical component that supports and guides the movement of a rotating shaft or other moving parts. It reduces friction between the moving parts and allows for smooth and efficient motion.

6200, 6300 & R Series Ball Bearing Dimensions & Sizes Chart

Ball bearings come in various sizes and configurations to accommodate different applications.The size of a ball bearing is determined by its dimensions, typically measured by the inner diameter (ID), outer diameter (OD), and width. These dimensions vary widely depending on the specific requirements of the application.Ball bearing sizes chart is a reference table that provides information about different ball bearing sizes, typically including their dimensions and load capacities. It helps users identify and select the appropriate ball bearings for specific applications based on their requirements.The chart typically includes information such as the inner diameter (ID), outer diameter (OD), and width of the bearing, which are important dimensions for determining compatibility and fit.

Additionally, load ratings may be included to indicate the maximum load that the bearing can withstand. while many manufacturers like BE-CU.COM also CNC machining process to produce non-standard bearings with unique characteristics. Here we post the commonly used ball bearing sizes chart and present how to define the ball bearings.

What is Ball Bearings?


Ball bearing is a type of rolling element bearing that uses balls to reduce friction between moving parts. It consists of an inner and outer ring with a set of balls in between, which are usually made of steel or ceramic. The balls roll along the raceways inside the rings, allowing smooth and efficient rotation of the bearing.

Ball bearings are commonly used in various applications, including machinery, automotive systems, aerospace equipment, and household appliances. They are designed to support radial and axial loads, providing high-speed and low-friction operation. The size and type of ball bearing required for a specific application depend on factors such as load capacity, speed, and environmental conditions.

6200 Series Ball Bearings


The 6200 series ball bearings are a specific type of ball bearing that belong to the deep groove ball bearing family. They are commonly used in various applications, including electric motors, machinery, appliances, and automotive components.The 6200 series bearings have the following characteristics:

  • Size: The 6200 series bearings typically have an inner diameter (ID) of 10 mm and an outer diameter (OD) of 30 mm. The width (W) of these bearings is typically 9 mm.
  • Load capacity: They are designed to handle moderate radial and axial loads.
  • Construction: These bearings consist of an inner and outer ring with a set of steel balls in between. They have a deep groove raceway, allowing the balls to rotate smoothly.
  • Material: The balls are usually made of steel, while the inner and outer rings are commonly made of chrome steel (sometimes stainless steel) to provide durability and corrosion resistance.
  • Lubrication: The 6200 series bearings often come pre-lubricated with grease to ensure smooth operation. Some bearings may also have shields or seals to protect against contamination.

Overall, the 6200 series ball bearings are versatile, widely available, and suitable for many general-purpose applications where moderate loads and high-speed operation are required.

6300 Series Ball Bearings


The 6300 series ball bearings are a specific type of deep groove ball bearings. These bearings are commonly used in various industrial applications, including machinery, motors, and equipment. The “6300 series” refers to a range of bearings with a specific size and design, typically with a bore diameter of 10 to 50 millimeters. These bearings have a single row of balls that run deep within the inner and outer raceways, allowing them to handle both radial and axial loads. The 6300 series bearings are known for their durability, high-speed capabilities, and versatility in different operating conditions.

R Series Ball Bearings


The R series ball bearings are a specific type of inch-sized deep groove ball bearings. The dimensions of R series ball bearings can vary depending on the specific bearing size within the series.

Generally, R series ball bearings have an outer diameter ranging from 0.375 inches (9.525 mm) to 2.625 inches (66.675 mm). The inner diameter (bore) can range from 0.125 inches (3.175 mm) to 1.375 inches (34.925 mm). The width or thickness of the bearing can vary as well, typically ranging from 0.156 inches (3.96 mm) to 0.5 inches (12.7 mm).

It’s important to note that the dimensions can differ for different sizes within the R series, so it’s always advisable to refer to specific bearing catalogs or manufacturers’ specifications for accurate dimensions of a particular R series ball bearing.
