Understanding the 6208 Bearing Size A Comprehensive Overview

Bearings are essential components in various machines and mechanical systems, playing a vital role in reducing friction between moving parts. Among the many types of bearings available, the 6208 bearing size is notable for its widespread use in various applications due to its reliability and efficiency. This article provides an in-depth examination of the 6208 bearing, its specifications, applications, and maintenance tips.

What is a 6208 Bearing?

The 6208 bearing is classified as a deep groove ball bearing, which is one of the most common types used in industrial and commercial applications. The designation 6208 follows a standardized numbering system established by the International Organization for Standardization (ISO). The 6 indicates that this is a deep groove ball bearing, while 208 specifies the bearing’s series and dimensions.

Dimensions and Specifications

The 6208 bearing has specific dimensions that make it suitable for various applications. The key dimensions include

- Inner Diameter (ID) 40 mm - Outer Diameter (OD) 80 mm - Width (B) 18 mm

Additionally, the 6208 bearing typically has a dynamic load rating of approximately 16,000 N and a static load rating of around 8,300 N. The maximum speed of this bearing can vary based on the type of grease and operating conditions but generally can handle speeds up to 10,000 rpm.

The 6208 bearing is commonly made of high-quality steel, which provides durability and resistance to wear and tear. It is also available with different seals and shields to protect against dust and contaminants, which can enhance its performance and lifespan.
