Understanding 695ZZ Bearing Dimensions

Bearings are crucial components in many machines and mechanical applications, providing support and reducing friction between moving parts. Among the multitude of bearing types, the 695ZZ bearing is widely recognized for its unique dimensions and versatile applications. This article will explore the dimensions of the 695ZZ bearing, its significance, and its applications across various industries.

What is a 695ZZ Bearing?

The 695ZZ bearing is a type of miniature deep groove ball bearing. The 695 designation indicates specific dimensional characteristics, while ZZ denotes that the bearing features metal shields on both sides for enhanced protection against contaminants and lubrication retention. Typically made from high-quality steel, this bearing type is designed to handle moderate radial loads while providing smooth rotation, making it suitable for various low to medium-load applications.

Dimensions of 695ZZ Bearings

Understanding the dimensions of the 695ZZ bearing is essential for engineers and technicians who select bearings for specific applications. The standard dimensions for a 695ZZ bearing are as follows

- Inner Diameter (ID) 5 mm - Outer Diameter (OD) 13 mm - Width (W) 4 mm

These measurements define the bearing's size and compatibility with other components in a mechanical assembly. The 5 mm inner diameter allows it to fit onto shafts with a matching diameter, while the 13 mm outer diameter and 4 mm width provide the necessary structural integrity to accommodate loads effectively.

Load Capacity and Performance

Like all bearings, the load capacity of the 695ZZ is an important factor when considering its application. The dynamic load rating (C) of a 695ZZ bearing typically ranges from around 1,100 to 1,400 N, depending on specific construction and materials used. The static load rating (C0), which refers to the maximum load the bearing can support while stationary, varies between 560 to 700 N. These ratings indicate that while the 695ZZ bearing is suitable for a range of applications, it is not designed for heavy-duty use.

The performance in operational conditions is also influenced by factors such as speed and lubrication. The 695ZZ bearing can operate effectively at speeds up to 30,000 RPM under optimal conditions, making it suitable for applications requiring high rotational speeds. Proper lubrication—whether through greasing or oiling—ensures longevity and efficiency in performance.

The versatility of the 695ZZ bearing allows it to be used in a variety of applications. Some common uses include

1. Electronics Due to their small size and ability to handle moderate loads, 695ZZ bearings are often found in small motors, fans, and other electronic devices. 2. Robotics In robotic applications, these bearings are commonly used in joint mechanisms and actuators where space is limited, but smooth movement is critical. 3. Modeling and Hobby Projects Hobbyists often utilize the 695ZZ bearing in remote-controlled cars, drones, and model trains, where low friction and weight savings are essential. 4. Automotive In certain automotive applications, 695ZZ bearings can support small rotating parts, contributing to the overall efficiency and performance of the vehicle.

5. Industrial Machinery In conveyor systems and lightweight industrial machine components, these bearings provide an effective solution for achieving rotational movement with minimal friction.

Conclusion

The 695ZZ bearing is a well-engineered component that plays a significant role in many mechanical systems. With its specific dimensions and versatile applications, it demonstrates the importance of selecting the right bearing for optimal performance. As industries continue to innovate and develop new technologies, the demand for reliable miniaturized components like the 695ZZ bearing will undoubtedly grow, making it an essential component in a range of modern applications. Understanding its dimensions, capacities, and applications allows engineers and users to make informed decisions, ensuring the reliability and efficiency of the systems they design and maintain.
