KD055CP0 Bearing Product Overview & Core Advantages
The KD055CP0 is a thin-section open bearing designed for applications requiring compact design and high precision in inch measurements. As a single-row ball bearing with an open construction, it excels in handling radial loads efficiently while maintaining minimal cross-section dimensions. Its ABEC-1 precision class ensures reliable performance in precision mechanisms, and the brass cage contributes to smooth operation and durability. This bearing is pre-lubricated for immediate use, offering a balanced solution for space-constrained, high-accuracy applications.

KD055CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With only 0.5" width and 1:1 ratio between bore and outside diameter, this bearing enables compact machinery design while maintaining structural integrity.
Precision Engineering: Manufactured to ABEC-1 standards with tight dimensional tolerances (±0.0010") ensuring high running accuracy and consistent performance.
Superior Load Capacity: The single-row deep groove raceway provides excellent radial load capacity (2064 lbf dynamic, 4100 lbf static) despite the thin cross-section.
Enhanced Durability: Chrome steel rings and balls combined with a brass cage deliver reliable operation, reduced friction, and extended service life.
Optimized Internal Clearance: Controlled radial internal clearance (0.0000 – 0.0005") ensures smooth operation and minimal vibration in precision applications.
