A. Inner diameter of the 686 bearings
The inner diameter of the 686 bearing is 6 millimeters. It can accommodate shafts with a diameter of 6 millimeters.
B. Outer diameter of the 686 bearings
The outer diameter of the 686 bearing is 13 millimeters. This refers to the diameter of the outer ring of the bearing. Make sure that your application space can accommodate the outer diameter of the 686 bearings.
C. Width diameter of the 686 bearings
The width of the 686 bearing is 3.5 millimeters. This refers to the distance between the inner and outer rings of the bearing. Ensure that this dimension is suitable for your application to ensure proper installation and operation.
686 Detailed Dimension Information 
The 686 bearing is a common and widely used bearing model. Understanding its inner diameter, outer diameter, and width dimensions is crucial for selecting the appropriate bearing. Based on your application requirements, load, speed, temperature, and quality criteria, choose the suitable size of the 686 bearings for your application to ensure good performance and reliability.

Inner Ring: This is the inner part of the bearing, usually circular in shape, and it is placed on the shaft. The inner ring often features a hollow cylindrical shape to accommodate the shaft.
Outer Ring: The outer ring is a circular component that surrounds the inner ring. It's typically fixed to the bearing housing or external components. The outer surface of the outer ring is usually designed to withstand external loads.
Balls: Rolling balls are spherical components within the bearing that reduce friction between the inner and outer rings and support the load. These balls roll between the inner and outer rings to maintain smooth movement under load.
Cage: The cage is a component that supports the rolling balls. Its purpose is to maintain an even distribution of the balls, allowing them to roll smoothly while preventing collisions between the balls.
The sealing covers for the 686 bearing mainly come in two types: ZZ, and 2RS.

686 2RS refers to the 686 bearing with rubber seals as the outer cover. The rubber seals provide enhanced protection by effectively blocking moisture, dust, and other contaminants from entering. This sealing method is commonly used in harsh environments and applications that require stricter protection.
When choosing the appropriate bearing outer cover mode for your needs, consider the following factors
Application environment: Determine the potential sources of contamination and other external particles in your application environment. Based on the environmental conditions, choose between open type, metal shields, or rubber seals to provide the appropriate protection.
Precision and speed requirements: Consider the precision and speed requirements of your application. Open type bearings are typically suitable for low precision and lower speed applications, while metal shields and rubber seals offer higher protection and are suitable for medium and high precision requirements.
Maintenance requirements: Consider your maintenance needs for the bearings. Open type bearings require regular cleaning and lubrication, while metal shields and rubber seals can reduce maintenance requirements.
686 miniature bearings are also widely used in medical equipment, such as in dentistry. In this application, bearings are required to provide highly precise motion control and smooth operation to ensure accuracy and safety.
The 686 bearings is a crucial bearing model used in most pedal. This bearing has dimensions of 6mm inner diameter, 13mm outer diameter, and 3.5mm thickness. Its size design allows it to maintain low friction and high efficiency during high-speed rotation.
The 686 bearings are widely used in various mechanical equipment, such as small power tools, automation equipment, and more.
The 686 miniature bearing features compact dimensions and can be used in the wheels of remote-controlled cars, providing smooth motion and steering functionality, thereby enhancing the vehicle's control performance.
The 686 bearing is a key component widely used in various industries. From medical equipment and remote-controlled cars to the electric bicycle industry, this bearing plays an essential role in many critical devices. Its high-speed operation, durability, and reliability make it the preferred choice in these industries.
