Product Description

The KOYO RNU070823-3SH3 is a single-row cylindrical roller bearing designed for high radial load capacity and low friction performance.
This bearing features no inner ring (commonly used when the shaft itself serves as the raceway surface), making it ideal for compact assemblies where space and stiffness are critical.

The RNU-type designation indicates:

• RNU: Cylindrical roller bearing without inner ring.
• 070823: Dimensional series designation (specific to KOYO’s internal code).
• 3SH3: Special clearance or heat-treatment specification, typically related to higher-speed or elevated-temperature performance.

Because of its design, this bearing allows for axial displacement between the shaft and housing, making it suitable for applications with thermal expansion or alignment variations.
