Dimensions and Specifications for 629zz Bearing Variants and Applications

Understanding the Dimensions of the 629ZZ Bearing


The 629ZZ bearing is a small-sized ball bearing widely used in various applications due to its compact nature and efficient performance. This article delves into the dimensions and technical specifications of the 629ZZ bearing, providing insights into its suitability for different mechanical applications.


Overview of the 629ZZ Bearing


The 629ZZ bearing is part of the deep groove ball bearing family, characterized by its ability to accommodate both radial and axial loads. This bearing type is particularly popular in applications requiring a reliable and smooth rotation under varying load conditions. The designation ZZ in the name indicates that this bearing comes with metal shields on both sides, providing enhanced protection against dust and debris, thereby extending its lifespan.


Dimensions of the 629ZZ Bearing


To understand the applications and utility of the 629ZZ bearing, it is crucial to recognize its dimensions


- Inner Diameter (ID) 9 mm - Outer Diameter (OD) 26 mm - Width (B) 8 mm


These dimensions categorize the bearing as a small-sized component, ideal for applications where space is a constraint. The small ID makes it suitable for shaft sizes that require tight tolerances while accommodating varying speeds and loads.


Load Ratings


The 629ZZ bearing is designed to handle specific loads effectively


- Dynamic Load Rating (C) Approximately 5.68 kN - Static Load Rating (C0) Approximately 2.5 kN

These ratings indicate the maximum loads the bearing can handle during operation. The dynamic load rating represents the maximum load the bearing can support while in motion, while the static load rating applies when the bearing is stationary. These figures are crucial for engineers when designing systems that utilize such bearings, ensuring optimal performance and longevity.


Speed Ratings


Another vital aspect of the 629ZZ bearing is its speed performance. The bearing can operate at relatively high speeds, typically up to 50,000 RPM under optimal conditions. However, this speed rating can vary based on factors such as lubrication, load conditions, and the presence of thermal management solutions. Proper selection and maintenance of the bearing in operation can optimize its speed capabilities.


Applications of the 629ZZ Bearing


The compact dimensions and robust performance of the 629ZZ bearing enable its use in a wide range of applications, including


1. Electric Motors Commonly found in miniature electric motors used in household appliances and toys. 2. Robotics Utilized in small robotic devices for smooth movement and precision. 3. Bicycles Employed in hubs and freewheels for efficient wheel rotation. 4. Home Appliances Present in fans, pumps, and other low-to-moderate rotary applications. 5. Small Engines Suitable for use in small engines where space and weight savings are critical.


Advantages of the 629ZZ Bearing


The benefits of the 629ZZ bearing extend beyond its dimensions. Some key advantages include


- Durability The ZZ shields protect against contaminants, enhancing the bearing's lifespan. - Versatility Its small size makes it compatible with various mechanical assemblies. - Low Friction The design of the bearing allows for minimal friction during operation, contributing to energy efficiency. - Ease of Installation Its standardized dimensions enable straightforward integration into existing systems.


Conclusion


In conclusion, the 629ZZ bearing serves as an excellent solution for numerous applications that require a compact, durable, and efficient ball bearing. Understanding its dimensions, load ratings, speed capabilities, and advantages allows engineers and designers to make informed decisions when selecting bearings for mechanical systems. As technology continues to advance, the demand for such small yet powerful components will only increase, underscoring the importance of the 629ZZ bearing in modern engineering applications.
