KF045CP0 Bearing Structural Features & Performance Benefits
Thin Section Design: The KF045CP0 features an ultra-slim 0.75" width while maintaining a substantial 4.5" bore diameter, providing maximum space savings and weight reduction in compact assemblies. This thin section bearing design minimizes system envelope without compromising performance.
Premium Material Construction: Manufactured from high-grade chrome steel for both rings and balls, with a durable brass cage for optimal ball guidance and reduced friction. This material combination ensures excellent wear resistance and dimensional stability.
Precision Engineering: Built to ABEC-1 tolerance standards with tight dimensional controls, including bore and outside diameter tolerances of -0.0008" to 0". The radial internal clearance of 0.0000" to 0.0005" ensures precise operation and minimal vibration.
Load Capacity: With a dynamic radial load rating of 3750 lbf and an ISO radial rating of 6605 lbf, this bearing delivers reliable performance in demanding applications while maintaining the benefits of thin-section design.
