## Overview

The INARNA6903 Precision Needle Roller Bearing is designed for high-performance applications, featuring a robust steel cage, a compact design, and a maximum rotational speed of 19000rpm. Its lubrication groove and oil hole facilitate easy maintenance, making it an ideal choice for professionals seeking reliability and efficiency in their machinery.

## Description

This INA radial needle roller bearing has a steel cage and is suitable for applications with high dynamic and static loads. The steel cage provides guidance and even spacing of the rollers for reduced friction, vibration, and noise when operated at high speeds. The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance, and the outer ring has a lubrication groove and an oil hole for applying lubrication in place. The bearing is factory lubricated with lithium complex soap grease, and can be used at temperatures from -4 to 248 degrees F (-20 to 120 degrees C). This radial needle roller bearing meets Deutsches Institut für Normung standard DIN 617 and International Organization for Standardization standard ISO 1206 for quality assurance, and is used in various applications, such as automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.Roller bearings use rolling elements to maintain a separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.INA manufactures bearings for automotive and industrial applications. The company is part of the Schaeffler Group, founded in 1946 in Herzogenaurach, Germany, and meets International Organization for Standardization (ISO) standards 9001:2008 and TS 16949:2009 for quality assurance.
