Bore type:Needle roller bearing
Radial needle roller bearing for applications with dynamic and static loads
High load capacity with a reduced cross section for use in restricted spaces
Reinforced polyimide nylon cage guides and evenly spaces rollers to reduce friction, vibration and noise
Hardened high carbon chromium steel rollers for heat tolerance and durability under heavy loads
Oil hole to apply lubrication in place
This Light series radial needle roller bearing has a nylon cage and an oil hole in the outer ring, and is suitable for applications with dynamic and static loads. It has a reduced cross section (no inner ring) for use in tight mounting spaces. Reinforced polyimide nylon cage provides uniform roller spacing and orientation to reduce friction, vibration and noise when operating at high speeds. The outer ring has an oil hole to apply lubrication in place. Needle rollers are made from high carbon, hardened chromium steel for durability and heat tolerance. This radial needle roller bearing 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 gap 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 at both ends (a shaft can pass through) or open at one end and closed at the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce bearing life. If one end is sealed, the sealing component is an elastomeric lip that contacts the shaft. If shielded, the shield is a non-contact lip, usually made of metal. Roller bearings are used in a range of applications, from agricultural machinery to transportation equipment, robotics, dental equipment, elevators, mills, ship rudder shafts, and aggregate crushers, among others
