173110-2RS Detailed Dimension Information 
Inner and Outer Rings: The 173110 thin section bearing consists of inner and outer rings, which are the primary bearing rings. These rings are typically made from chrome steel material (material can be chosen based on requirements) and undergo precise machining and heat treatment to ensure their hardness and durability.
Steel Balls: The steel balls within the bearing are also usually made from chrome steel material (material can be chosen based on requirements). These balls are evenly distributed between the inner and outer rings, reducing friction through rolling motion and supporting axial and radial loads.
Cage: The cage is the component that supports the steel balls. It is usually made from plastic or metal and maintains the even distribution of the balls while minimizing collisions and friction between them.
Seals: Some 173110 thin section bearings may come equipped with seals to prevent dust, dirt, and other external objects from entering the bearing interior. This helps protect the lubricating grease and extends the bearing's lifespan.
The headset and bottom bracket of electric bicycles are more susceptible to water splashes or mud intrusion. Therefore, for the 173110 Thin Section Bearing, most of the bearing housings are equipped with rubber seals. The rubber seal provides enhanced protective performance by effectively preventing the entry of water, dust, and other contaminants. This sealing method is typically suitable for harsh environments and applications that require stricter protection.
When choosing the appropriate bearing seal pattern for your needs, the following factors should be considered:
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.
The 173110 bearing is an essential bearing model used in the headset and bottom bracket of most electric bicycles. This bearing has dimensions of 17mm inner diameter, 31mm outer diameter, and 10mm thickness. Its size design allows it to maintain low friction and high efficiency during high-speed rotation.
