Needle Roller Bearing

Composition of KT Series Needle Roller Bearing

KT radial needle roller and cage assemblies bearing is a kind of independent bearing unit with high load capacity and rigidity especially applicable for the tray of shaft and seat holes with the unit which is limited in radical dimension. Each needle have excellent operative characteristic due to each needle exactly guided and kept by the retainer

Characteristic of KT Series Needle Roller Bearing

Needle retainer assembly bearing has to bear a large centrifugal force, impact and vibration, working under the complicated load and high-speed rotating condition, there is a large sliding friction between the needle retainer assembly bearing and the rolling element, and a large amount of thermal energy will be generated. In the case of interaction with heat and force, it will lead to the failure of the needle retainer assembly bearing, and also cause the burn and breakage. Therefore, the needle retainer assembly bearing needs to have better thermal conductivity, wear resistance, elasticity, steel and processing technology, smaller coefficient of friction, density, proper strength and toughness fit, and the coefficient of expansion of the rolling elements.

Application of KT Series Needle Roller Bearing

Due to its light weight, high rigidity, large oil capacity, and ability to withstand harsh conditions such as high-speed rotation and impact loads, it has a wide range of applications in industries such as engineering machinery, machine tools, automobiles, metallurgy, mining, petroleum, and more.
