KD120CPO Bearing Product Overview & Core Advantages
The KD120CPO is a high-performance thin-section bearing engineered for applications demanding space optimization without compromising load capacity. As a Reali-Slim Open Bearing with a single row construction, it delivers exceptional radial load handling in a remarkably compact cross-section. Manufactured to ABEC-1 precision tolerances, this bearing ensures reliable operation in precision assemblies. Its open design facilitates easy lubrication, while the chrome steel construction provides durability and consistent performance across a wide temperature range from -30°C to 110°C.

KD120CPO Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent 0.5" cross-section width relative to its large 12" bore diameter, this bearing enables significant weight reduction and space savings in machinery design while maintaining structural integrity.
High Load Capacity: The optimized single row ball bearing construction delivers a dynamic radial load rating of 3,148 lbf and an impressive static radial load rating of 8,550 lbf, providing reliable performance under demanding conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore/OD tolerance: -0.0014" to 0"), ensuring smooth operation and precise positioning in critical applications.
Premium Materials: Chrome steel rings and balls combined with a brass cage provide excellent wear resistance, corrosion protection, and stable operation across the specified temperature range.
