Miniature Extended Bearings

Miniature extended bearings are compact and specialized components used in precision applications. These bearings feature an extended inner ring, providing additional support and stability. They are designed to accommodate higher radial loads and provide improved load distribution. Miniature extended bearings are commonly used in industries such as robotics, medical equipment, and electronics, where space is limited and precise rotational support is crucial. With their compact size, extended inner ring, and high-quality construction, these bearings offer reliable performance, enhanced load capacity, and excellent axial retention in demanding and space-constrained environments.

Advantages

Compact Size: These bearings are specifically designed to be compact and small in size, making them ideal for applications where space is limited. Their miniature form factor allows for easy integration into tight spaces without compromising performance.
Extended Inner Ring: The extended inner ring design provides additional support and stability to the bearing assembly. This extended section increases the bearing’s contact area with the shaft, resulting in improved load distribution and reduced stress concentrations, enhancing the overall performance and lifespan of the bearing.
Enhanced Load Capacity: Miniature extended bearings are engineered to accommodate higher radial loads compared to standard miniature bearings. The extended inner ring design allows for a larger contact area with the load-bearing surface, enabling these bearings to handle increased loads without compromising performance.
Improved Axial Retention: The extended inner ring of these bearings also contributes to enhanced axial retention. It helps prevent axial movement of the bearing, ensuring secure positioning and minimizing the risk of misalignment or loss of performance in applications with axial loads or vibrations.
Precise Rotational Support: Miniature extended bearings are designed to provide precise rotational support in precision applications. The extended inner ring and high-quality construction ensure smooth and accurate rotational motion, contributing to overall system precision and reliability.
Versatile Applications: These bearings find applications in various industries, including robotics, medical equipment, electronics, and more. Their compact size, extended inner ring, and precise rotational support make them suitable for applications that require precise motion control and stability in limited spaces.
