About SKF NKIA 5906 Radial And Thrust Bearing, Needle

This SKF combined radial needle roller bearing and angular contact ball bearing is suitable for applications with high radial loads and low axial loads in one direction. The bearing has a reduced cross-section compared to separate radial and thrust bearings for use in restricted spaces. The steel needle roller cage and glass fiber reinforced polyamide nylon ball cage provide guidance and even spacing of the rolling elements for minimum vibration and noise when operated at high speeds. The needle rollers and balls are made of through-hardened, high-carbon chromium steel for durability and heat tolerance. The bearing can be used at operating temperatures from -4 to 248 degrees F (-20 to 120 degrees C). This combined radial needle and angular contact ball bearing meets International Organization for Standardization standards ISO 15 and ISO 492 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. SKF manufactures bearings, seals, mechatronics, and lubrication systems. The company, founded in 1907 and headquartered in Goteborg, Sweden, meets International Organization for Standardization (ISO) standards 9001, 14001, and TS 16949 for quality assurance.
