bearing 51308_Dimensions and Specifications of the 6202 2Z Bearing for Various Applications

Understanding the Dimensions of 6202 2Z Bearings Bearings are essential components in various mechanical systems, allowing for smooth rotational or linear movement between parts. One popular type of ball bearing is the 6202 2Z bearing, widely used in electric motors, machines, and automotive applications. Understanding its dimensions and specifications is critical for engineers, designers, and maintenance professionals. What is a 6202 2Z Bearing? The designation 6202 2Z specifies certain characteristics of the bearing. The 6202 refers to the series and size of the bearing, while 2Z indicates that the bearing is shielded on both sides with metal shields. This design helps to keep lubricant within the bearing while preventing dirt and debris from entering, thus enhancing its longevity and performance. Dimensions of the 6202 2Z Bearing The dimensions of a 6202 2Z bearing are defined by a standard set of specifications - Inner Diameter (ID) 15 mm - Outer Diameter (OD) 35 mm - Width (W) 11 mm These dimensions determine how the bearing will fit into different applications. The inner diameter must match the shaft diameter on which it will be mounted, while the outer diameter and width are crucial for ensuring compatibility with the housing. Types of Shields and Their Functions The 2Z in the bearing designation indicates that this model has metal shields on both sides . These shields serve several purposes 1. Protection against Contaminants The shields prevent dust, dirt, and other particles from infiltrating the bearing's internal components. This protection is vital for maintaining the integrity of the lubricant and the bearings themselves. 6202 2z bearing dimensions 2. Retention of Lubricant The metal shields help to retain the grease or oil used to lubricate the bearing, reducing the frequency of maintenance and replacement. 3. Reduced Friction While the shields provide protection, they also create a low-friction environment, allowing the bearings to operate more efficiently. Applications of 6202 2Z Bearings 6202 2Z bearings find extensive use across various industries due to their robust design and reliability. Common applications include - Electric Motors These bearings are often found in small electric motors where space constraints require compact solutions. - Pumps They help in the smooth operation of pumps by facilitating the movement of rotating shafts. - Industrial Machinery Machines that require precise movement and reliability frequently utilize 6202 2Z bearings. - Automotive Components They are commonly used in different car parts, such as wheels and transmission systems, where consistent performance is essential. Maintenance and Lifespan The lifespan of a 6202 2Z bearing can vary widely based on several factors, including operating conditions, load, and maintenance practices. Regular maintenance involves checking for signs of excessive wear or damage. Ensuring that the bearing is adequately lubricated and that shields remain intact is essential for prolonging its life. In cases where the bearing is exposed to harsh conditions, it may be beneficial to consider variations that offer enhanced sealing or specialized materials. This approach can provide additional protection against moisture and particles. Conclusion In conclusion, the 6202 2Z bearing is a versatile and dependable component within many mechanical systems. Its dimensions, combined with the protective features of dual metal shields, make it an ideal choice for applications requiring durability and reliability. For engineers and maintenance personnel, understanding the specifications and proper care of these bearings is critical for ensuring optimal performance and longevity in their respective applications. Whether in the heart of an electric motor or within an intricate automotive assembly, the 6202 2Z bearing plays a vital role in modern engineering and performance.
