T-Blog, Your Bearing Wikipedia

Powder metallurgy (PM) is a technology that uses metal powder or nonmetal powder or its mixture as raw materials to manufacture metal materials, composite materials and various types of products through forming and sintering. Its three core elements are technology, materials and equipment, which are widely used in transportation, machinery, electronics, aerospace and other important industrial fields. It is the most potential and dynamic branch of new materials science.

Sealing devices can generally be divided into static seals (fixed seals) and dynamic seals (rotating seals).
The former is called gasket seal, and the latter is called gasket seal.

Sealing is indispensable for bearings. Sealing can not only prevent the leakage of lubricant, but also prevent the invasion of harmful foreign bodies. Otherwise, it will cause the abrasive wear of the bearing raceway, reduce the service life of the bearing, and make the bearing parts corroded by harmful gas and moisture, and accelerate the aging of the lubricant.

TBB can provide various types of maintenance-free spherical plain bearings.

“Maintenance-free” is an industry-wide term used to describe plain bearings and rod ends with self-lubricating sliding contact surface combinations.
These so-called maintenance-free bearings and rod ends offer a number of advantages for OEMs and end users alike. These advantages, which include minimal maintenance and reduced lubricant consumption, quickly compensate for the difference in the initial purchase price. And of course, the impact that maintenance-free bearings have on the environment is an added benefit.

Here are some examples of applications in which spherical roller bearings might be used: Vibration Screen Bearing, Wind turbine bearings, Papermaking mills bearings, Continuous Caster bearings & etc.

Here you can find some application cases for slewing bearings used in indoor EVs

Spherical Roller Bearings have many different structures, such as CC type, CA type, E type from SKF and MA type, MB type, E1 type from FAG. Now let me give you a detailed introduction of the difference between these designs.

Slewing bearings usually have a diameter ranging from 0.2 to 10 meters. They consist of mounting holes, internal or external ring gears, lubricating oil holes, and sealing devices. The mounting holes are divided into through holes and threaded holes. Different for different industries The slewing bearing has a variety of structural types to meet its requirements, and can meet the needs of the main engine function with different manufacturing accuracy levels. Therefore, the slewing bearing is an indispensable machine on the slewing device of medium and large construction machinery slewing bearing. component. It plays an important role in the machinery industry, construction industry, coal industry and shipbuilding industry. The slewing bearing has toothless type, external tooth type and internal tooth type. The structure types slewing bearing generally include single-volley, double-volley, cross-roller, three-row roller, ball-column combined and other forms, of which single-row ball The slewing bearing has a relatively low cost and excellent overall performance. The double volleyball slewing bearing has certain advantages in service life, strong bearing capacity, small swing resistance, large allowable wear, and strict requirements for the mounting base. Raceway rotation accuracy is low; Crossed roller slewing bearings have high accuracy, long life, and high dynamic load capacity, but have high…
