KF040CP0 Bearing Product Overview & Core Advantages
The KF040CP0 is a thin-section open ball bearing designed for applications requiring compact design and high precision in inch-dimensioned machinery. As part of the Reali-Slim series, it features a single-row construction optimized for radial load applications while maintaining minimal cross-section. Manufactured to ABEC-1 precision with chrome steel components, this bearing delivers reliable performance in space-constrained assemblies where weight reduction and dimensional accuracy are critical.

KF040CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The KF040CP0 features a minimal cross-section (0.75" width) with 4" bore and 5.5" OD, enabling space-saving integration while maintaining structural integrity.
Premium Material Construction: Chrome steel rings and balls combined with a brass cage provide excellent wear resistance and dimensional stability under radial dynamic loads up to 3559 lbf.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore tolerance: -0.0008"–0", width tolerance: +.000 –.005") ensuring consistent performance in precision applications.
Optimized Internal Clearance: Radial internal clearance of 0.0000 – 0.0005" provides smooth operation while minimizing play in precision assemblies.
KF040CP0 Bearing Typical Application Areas
The KF040CP0 thin-section bearing is ideally suited for:
- Robotics and automation systems requiring compact, lightweight bearing solutions
- Aerospace components and aircraft control mechanisms
- Medical equipment including scanning devices and precision instruments
