INA PNA25/47 Needle Roller Bearing, With Inner Ring, Self Aligning, Precision, Steel Cage, Open End, Metric, 25mm ID, 47mm OD, 20mm Width, 9000rpm Maximum Rotational Speed

Key features

• Radial needle roller bearing for applications with high dynamic and static loads
• Inner ring provides a hardened and ground raceway
• Compensates for static misalignments of up to 3 degrees between the shaft and housing
• Steel cage guides and evenly spaces rollers for reduced friction, vibration, and noise
• Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads

This INA self aligning radial needle roller bearing has an inner ring and a steel cage, and is suitable for applications with high dynamic and static loads. It has a spherical outer ring and a concave plastic support ring, which allow the bearing to compensate for static misalignments of up to 3 degrees between the shaft and housing. The inner ring provides a hardened and ground roller raceway for applications in which the shaft cannot be used as a raceway. 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. This self aligning radial needle roller bearing can be used at temperatures from -4 to 248 degrees F (-20 to 120 degrees C), 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 f
