**Common Sense of Rolling Bearings** Home > Bearing Knowledge > Common Sense of Rolling Bearings Source: China Bearing Network | Time: 2014-08-15 Rolling bearings are a fundamental component in many mechanical systems, designed to reduce friction and support loads efficiently. Unlike sliding bearings, which rely on direct surface contact, rolling bearings use rolling elements—such as balls or rollers—to minimize friction and improve performance. These bearings consist of four main parts: the inner ring, outer ring, rolling elements (balls or rollers), and the cage that separates and guides the rolling elements. The inner ring typically fits onto the shaft, while the outer ring is mounted in a housing or bearing seat. The rolling elements move between the two rings, allowing smooth rotation. The cage ensures even spacing and prevents the rolling elements from colliding, contributing to the bearing’s durability and efficiency. Rolling bearings can be classified based on several factors, including the type of load they carry and their design. Radial bearings handle primarily radial loads, while thrust bearings manage axial forces. Bearings can also be categorized by the shape of their rolling elements—ball bearings or roller bearings. Roller bearings include cylindrical, tapered, and spherical types, each suited for different applications. In addition, bearings may be self-aligning, meaning they can accommodate misalignment, or non-aligning, which are rigid and used in precision applications. They can also vary in the number of rows of rolling elements, such as single-row, double-row, or multi-row bearings. The size of a rolling bearing is another important classification. Bearings are typically categorized into miniature, small, medium, large, and extra-large sizes based on their outer diameter. This helps engineers select the right bearing for specific machinery requirements. The manufacturing process of rolling bearings involves several stages, starting with the production of the inner and outer rings, followed by the creation of the rolling elements and the cage. Each part undergoes machining, heat treatment, and finishing processes to ensure high precision and durability. Once all components are ready, they are assembled in a controlled environment to maintain quality and performance. Compared to sliding bearings, rolling bearings offer several advantages. They have lower friction, higher efficiency, and are easier to maintain. Their standardized design allows for mass production, making them widely available and cost-effective. Additionally, rolling bearings can handle both radial and axial loads, simplifying machine designs. However, rolling bearings are not without limitations. They are more sensitive to contamination and can experience noise and vibration under certain conditions. In high-precision applications, sliding bearings might still be preferred. Despite these drawbacks, rolling bearings remain the dominant choice in most mechanical systems due to their reliability and versatility. In conclusion, understanding the basics of rolling bearings is essential for selecting the right type for any given application. Whether it's for industrial machinery, automotive systems, or precision equipment, rolling bearings play a critical role in ensuring smooth and efficient operation. As technology advances, the development of new materials and designs continues to enhance the performance and lifespan of these vital components.

Solenoid Armature Tube OD 8mm Below

BRANDO is a Solenoid Valve Armature Plunger manufacturer and exporter in Ningbo, China, which has more than 10 years experience.

The armature assembly or anchor system is the very important component of Solenoid Valve. An internal stainless steel plunger moves up and down to seal on the top and bottom valve seats. Brando provides armatures in multiple sizes depending on the application's flow requirement. Four common pneumatic functions are available which include:

1. 2/2 normally closed(NC),
2. 3/2 normally closed(NC),
3. 2/2 normally open(NO),
4. 3/2 normally open(NO).

The seals in the plunger are NBR (standard), but FKM, HNBR, PTFE, EPDM are available for different media and temperatures. Most of our armatures are designed to accept AC and DC voltages. Some armatures are DC only for low watt applications.

Brando offers flexibility as the connection to the seat cavity can be with a thread/o-ring seal style or o-ring flange style that requires a mounting plate.
