NA4905 Needle Roller Bearings With Machined Rings

Needle roller bearings with machined rings are bearings with a low sectional height and large load ratings. The outer ring has a spherical raceway and its center is located on the bearing axis. Needle roller and cage assemblies are fitted within the inner ring. Cage types and designs are optimized to sustain high loads at high speeds and low friction. The bearings have very good radial load-carrying capacity and high axial stiffness. Additionally, they are easy to fit and disassemble.

NA4905 needle roller bearings are typically used in high load and high speed applications such as automotive and aerospace applications. There are available in a variety of sizes and configurations to meet the needs of different applications. They are usually made of high-quality materials such as steel or stainless steel, which are durable and have a long service life. Needle roller bearings NA4905 can operate at high speeds and can withstand high loads.
