Koyo NTA-4458 Needle Roller and Cage Thrust Assembly, Open, Steel Cage, Inch, 2-3/4" ID, 3-5/8" OD, 1/8" Width, 54.5lbf Static Load Capacity, 9.38lbf Dynamic Load Capacity

The steel cage on this Koyo thrust needle roller and cage assembly is ideal for applications with high dynamic axial loads. The cross-section is smaller. For use in tight spaces, this bearing has a smaller cross section than a standard thrust bearing. The cage is made of hardened steel for greater strength, rigidity, and heat resistance than nylon cages, and it provides guidance and even spacing of the rollers for reduced friction, vibration, and noise when operating at high speeds. The needle rollers are made of a material that is resistant to wear and tear. high-strength, hardened Carbon chromium steel is used for durability and heat tolerance under heavy loads, and the ends are contoured to distribute contact stress evenly. The American National Standards Institute/American Bearing Manufacturers Association standard ANSI/ABMA 21 is met by this thrust needle roller and cage assembly. It's used in a variety of applications, including automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-way radios. Among other things, there are cycle engines. br>br>Roller bearings use rolling elements to keep moving parts separated, reducing rotational friction and supporting radial and axial loads. These components can be any of the following: a ball, a cylindrical, a spherical, a barrel, a needle, a spindle, or a tapered spherical spherical spherical Roller bearings can have both ends open (allowing a shaft to pass through) or one end open and the other closed. To protect the bearing from solid contaminants and moisture that could shorten its lifespan, an open end can be sealed or shielded. An elastomer lip that contacts the shaft acts as a sealant if an end is sealed. If it's shielded, it's a non-removable shield. Metal contact lip is the most common type. Agricultural machinery, conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers are just a few of the applications for rolling bearings. br>br>For automotive and industrial applications, Koyo Bearings USA produces needle roller bearings, bearing assemblies, and needle rollers. The company, which was founded in 2009 and is based in Canton, Ohio, adheres to the ISO 14001 and TS 16949 quality assurance standards.
