61820 High-Performance Thin-Wall Bearings 618 Series with Copper Cages for Industrial Applications

Product Description:

Thin-wall bearings are a special type of bearings, characterized by a ratio of the inner diameter to the outer diameter of the bearing that is less than a specified value (usually less than 1.25), so the bearing wall is relatively thin, hence the name thin-walled bearings. Thin-walled bearings are mainly composed of inner rings, outer rings, rolling elements, and cages. Among them, the inner ring and outer ring are the main parts of the thin-walled bearing, the rolling elements roll between the inner and outer rings, and the cage is used to keep the rolling elements in a stable position to prevent them from colliding with each other. The inner and outer rings of thin-walled bearings are usually made of high-strength materials, such as stainless steel, high-carbon steel, etc., to ensure their load-bearing capacity and stability. The rolling elements are made of spherical or cylindrical high-hardness materials, such as ceramic balls, carbide balls, etc., to improve the rotation accuracy and wear resistance of the bearings. The cages are mostly made of lightweight materials, such as aluminum alloys, polymers, etc., to reduce the overall weight of the bearing.

Features:

1. Lightweight and compactness: Since the inner and outer ring walls of thin-walled bearings are relatively thin, the overall weight is light and the structure is compact. This design makes thin-walled bearings particularly useful in applications where space is limited, and can reduce the size and weight of the overall equipment.
2. High precision: Thin-walled bearings generally have high dimensional accuracy and rotational accuracy. This makes them excel in applications that require precise control of rotational motion, such as precision machine tools, instrumentation, and medical equipment.
3. High load capacity: Although thin-walled bearings have thin walls, they can still withstand fairly high loads. This is due to the high-strength materials used and the optimized structural design, which ensures the stability and reliability of the bearings when subjected to heavy loads.
4. Good running smoothness: The rolling element and cage design of thin-walled bearings helps to reduce vibration and noise during operation and provide smooth rotational motion. This is especially important for applications that require low noise and high precision.
5. Easy to install and maintain: The compact design of thin-walled bearings makes them relatively easy to install into equipment. At the same time, due to their relatively simple structure, maintenance and replacement are also relatively convenient.
6. Wide range of applications: Due to the above advantages, thin-walled bearings are widely used in various fields, including aerospace, automotive industry, precision machinery, medical equipment and robotics. These applications have different performance requirements for bearings, but thin-walled bearings can provide reliable solutions.
7. High speed capability: Thin-walled bearings usually also have high speed capabilities and can maintain stable performance at high speeds. This makes them advantageous in applications that require high-speed rotation, such as motors, fans and pumps.
8. Good corrosion resistance: Some thin-walled bearings are made of corrosion-resistant materials such as stainless steel and can work in harsh environmental conditions, such as environments with moisture, corrosive gases or liquids.
